What's New for Quick Terrain Modeler Version 7.1.5

Universal Coordinate Support:

QTM v7.1.5 will now support data in any known coordinate system. Where previous versions of QT Modeler worked with UTM, Lat/Long, and a catch-all "Cartesian" system for everything else, the new release will recognize and interact with US State Planes and any other coordinate system natively - with no compromises. These enhancements will allow:

• Import/export of 3D, raster, and vector data in any known coordinate system.
• Manual override of coordinate geokeys during import and export.
• Synchronization with Google Earth, regardless of coordinate system loaded.
• Overlay of 2D imagery onto 3D models, even if the imagery is in a different coordinate system than the point cloud/DEM.
• Export of properly geotagged analysis products and annotations, regardless of coordinate system.
• Store frequently used coordinate systems as a "Custom" coordinate system to return to later in coordinate system specification interface,

You can begin using this capability by simply opening LAS files or importing data in any coordinate system. You will see the coordinate system in the import interfaces and in the status bar once your data is loaded.

2D Only Mode - No 3D Data Needed!

Load 2D imagery without 3D data loaded. This will enable the viewing and interaction with 2D imagery in locations where LiDAR and other 3D data may not be available. Almost all known imagery formats will be supported, including GeoTIFF, MRSID, ECW, NITF, and CIB. While you won't get the benefit of 3D analysis, you will still be able to measure distances, convert locations between UTM/LatLong/MGRS, create routes, synchronize Google Earth, annotate scenes, export directly to PowerPoint, and many more functions. To use this simply "Import Texture" rather than "Load Model" to load a specific image. To search for 2D imagery, go to the Model Search tool (File Menu) and select the Image Search (2D Data) radio button at the top of the window. Note: QT Modeler can search for both 2D imagery (GeoTIFF's, MRSID, NITF, etc.) and 3D data (LAS files, DEM's, etc.), but not at the same time.

Enhanced, Real-time LAS filtering:

Using QT Modeler's "QTA" structure and advances in graphics card capability, you will be able to interactively filter and recolor data in real time based on LAS attributes (e.g., intensity, classification, etc.) as well as attributes appended by QTM (e.g., height above ground level, point density, etc.), thus blending rigorous quantitative analysis (e.g., show me the points whose intensity is between 500 and 1500) and real time visualization. You will find both QTA continuous filtering (for continuously varying attributes such as intensity, Z, height AGL, etc.) and QTA discrete filtering (for attributes that have just a few possible values, such as classification or return number) in the Analysis menu... QTA Attribute Analysis. You will need to load attributed data (e.g., LAS file) for this functionality be available.

Model and Image Opacity Control:

Version 7.1.5 adds the ability to control opacity of models, vertex colors (e.g., intensity and/or analysis results), and textures (i.e., overlaid imagery), base model colors, and height coloration. This tool is accessed from the layer tree in the "Special Overlays" folder. It will only be available if your video card runs OpenGL version 2.1 or later. We have been working hard to take advantage of recent, and some not so recent, advances in video card and GPU technology. QTM will now poll your video card to see if it can support some advanced graphics tools and techniques and, if it can, enable new capabilities. The initial capabilities included in this build are much more flexibility in combining colors, more flexible filtering, and enhanced rendering techniques. Flexibility in combining colors will give the user the ability to set opacity levels in models and overlaid imagery and even determine which images should take priority when there is overlap. Flexible filtering means faster definition of filtering criteria (e.g., filter above a certain intensity value) and real time application of filtering actions (e.g., color all points greater than n intensity value red, using a slider bar). Enhanced rendering means taking advantage of GPU power to render faster and keep the 3D scene at a higher level of detail. There is more to come on this topic.

Dockable Minimap:

Users can now undock the minimap, make it very large, and use it as a context and annotation window when exploiting large, complex data sets and imagery. The minimap now supports functions that were previously only supported in the main model display window. Among the new features supported:

• Added button to minimap toolbar to "undock" minimap as a secondary window.
• Increased resolution of mini-map image to better support large, floating mini-map windows.
• Status bar coordinate readout should now track both mini-map and main display (i.e., coordinate readout in stats bar will work on minimap).
• Minimap should get cleared out when you remove models from the layer tree as well as from the "Clear All" button.
• Create markers (hold down 'M' and click)
• Place mensuration line (type S, E, C, and click)
• Place Vectors (Press V) now works on the minimap
• Coordinate Conversion: Pressing 'P' to call up coordinate converter now works on the Minimap.
• Create range rings (Press R)

Terrain Hugging Lines, Routes, and Selection Areas:

Users can now choose measurement lines and routes to hug the terrain, thus getting a more intuitive feel for the terrain - whether you are going to be analyzing it or walking through it. Selection areas also snap down to the terrain. To enable terrain hugging measurement lines, place a measurement line in the terrain, and then click "Options" in the mensuration window. You can choose "Floating" (the old way), "Terrain Hugging", or "Both".

Reversible Scroll Wheel:

Perhaps the most requested feature of all! This is simply a switch to make the zoom functionality on the scroll wheel behave as it does in other applications (e.g., Google Earth). Simply go to the Control Menu... Control Mode and Check "Google Earth Style Zoom". Now pulling the mouse wheel towards you zooms out, pushing the scroll wheel away from you zooms in. Note to QTM purists, please note that this is an option only. We have resisted this for a while, but finally caved in to user demand.

Flexibility for Sentinel Floating Licenses:

Sentinel-based floating licenses will be able to point to a specific IP address for the license server, making it easier to set up centralized licensing in more complex internal networks. There is no need to do anything to access this functionality. If QTM fails to finds a Sentinel dongle, it will prompt the user for an IP address. Users can also hard code an IP address in the INI file.

Tweaks and Enhancements

• Added a "LAS Open" configuration tool to permit setting user preferences when "opening" rather than "importing" LAS files. File->"Options/Settings"->"LAS Open Options"
• QT should no longer apply classification filters when "Open"ing LAS files. You have to do an import for the classification filter to be honored.
• Should now fully support LAS classification (withheld, synthetic, etc.)
• LAS Classification filter now includes a "include withheld points" checkbox to alleviate the need for large numbers of checkboxes.
• Tweaked OPEN behavior for LAS such that if RGB channel is all zeroes, QT switches over to using intensity.
• QT should now retain citation geokeys when exporting LAS.

• "Add Texture" from toolbar, left click simply opens, right click opens standard import interface.
• "Add Texture" from toolbar will allow you to select multiple textures.
• Tweaked determination of max textures/max texture size.
• Implemented 3D fit for unregistered imagery.
• Changed "Close" button in texture import texture user interface to "Cancel".
• Tweaked handling of border in Unregistered Image user interface.
• Unregistered Image user interface is now resizable.
• Updated to ECW v4.2

• Added optional toolbar button for Image Export to GPS. Now just click a button to export screen as a custom map to Garmin handheld GPS.
• Mission export to GPX now has dialog to determine what exactly gets exported to which layers.
• Added option to export missions, markers, mensuration, selection, and vectors to SHP (Geodetic Lat/Long). This format is compatible with Falcon View.
• Added "Import Mission" option to layer tree "routes" context menu.
• Added options for Routes and Mensuration Lines to display as either "Floating", "Terrain Hugging", or "Both".
• Added the ability to export markers in MGRS coordinates to text file.
• Added ability to import "Current.gpx" track file from Garmin GPS to a QT Modeler route with markers.

• Reworked QTT file format to permit storage of a wider variety of coordinate systems and other information. This format will be incompatible with past releases of QT Modeler.
• Added option to export QTT files as v7.1.4 format to enable compatibility with previous versions.
• Updated to GDAL v1.8.1
• Added RTXYZI support.
• Expanded support for Lockheed FXYZI files.
• Added support for Lockheed C3D Marker CSV files.
• Added *.ASC to ASCII file filters.
• Added "Extension" capability to QTT/QTC/QVC/MRK/QTA formats, so that additional information can be added to future releases/formats without breaking compatibility with existing QTM.
• QT should now retain citation geokeys when exporting LAS.
• Added QVC Models to "Import Vector" file filter.
• Added IMG to model search filter.

• The Help menu, "About OpenGL" dialog now contains options to affect the OpenGL implementation on a given computer. Right now "Use Antialiasing" and "Use Advanced GL Shaders" are both toggle-able.
• Optimized CPU usage during idle states.
• When you "Clear Black" in the texture editor, black is now set to "transparent" and treated accordingly by the Advanced GL renderer.
• Added startup warning for Intel Video. In many cases, Intel integrated graphics chips do not support OpenGL, thus making point cloud rendering painfully slow.
• Should now auto-detect if a video driver cannot support the new Annotation Layer.

• Added "Show as Mensuration" to context menu for vectors in the layer tree.
• Added "Show as Selection" to context menu for vectors in the layer tree.
• Real Time Contours will now also function somewhat on point clouds.
• QTT ray tracing code will now properly handle "partial cells" - i.e. grid cells in which only one triangle is present rather than two (one corner is NoData). Before these were treated as if completely filled.
• Added min/max/mean/stddev readouts to histogram display in Model Info panel.
• Helicopter Landing Zone (HLZ) analysis should now be both faster and more accurate.
• Reworked Selection Area display. The old "shower curtain" is gone and is replaced with a terrain-hugging highlighted area with a 3D "cage" around the top.

• Added option to Modeler toolbar editor to load "Tactical Defaults". This will load the values from a "TacticalToolbar.qtb" file in the QT executable directory.
• Added the ability for QTM to guess units when reading Geodetic LAS with no units specified whatsoever (i.e., poorly written or missing geokeys in LAS file).
• Added means to turn off 2D scale in layer tree "Special Overlays".
• Added "Open File(s) as List" checkbox to "Open File" dialogs. This allows the user to select a file consisting of an ASCII list of file paths which QT will then treat as if you had selected all of those files through the dialog. This is a good tool to get around limitations in selecting multiple files from multiple directories, or to just compile a list of files externally to QTM.
• QTC/QVC/OGR/QTT models now calculate mean/std in the same manner as QTA.
• Where possible Merge Models now performs a QTA merge rather than exporting to FXYZ and reimporting. This is both much faster and preserves the QTA attributes. This can only be done if all the files match (i.e., same number and type of QTA attributes).
• Added checkbox to "Gridding Options" to "Explicitly use the tie point as the Grid Origin". This makes the lower-left corner of the grid be hard-coded as the tiepoint - regardless of all other considerations. This should be used with care, as if you provide a bad number you could easily end up cropping data or generating an empty grid.
• Tweaked status bar display of coordinate in point clouds to more reliably produce an answer other than "N/A".
• QT should do a better job of refreshing the search update popup. In some instances the "stop search" button was not visible, i.e., searches could not be stopped.
• Added some better import/export handlers for mismatched units (horiz in feet, vert in meters, etc.).
• Should now be able to successfully import a vector type with multiple data types (points, lines, etc.) and export to SHP (though it will be broken up into multiple files since SHP only supports one type per file).
• Added "Open QT Model" to Batch Scripting action list.
• "Set Screen Size" now incorporates the screen aspect ratio and lets the user set it to the aspect ratio of full-sized PowerPoint image export. I.e., if you want to create a PowerPoint presentation in which the whole slide is an image.
• "Clear All" will now clear Bookmarks and Minimap
• Tweaked number of decimal places displayed in some text readouts.
• Merge Models should now preserve added QTA features like AGL.
• Added option under "Control"->"Control Mode" to reverse mouse-wheel zoom to be like Google Earth.
• Added "Native" units to GridStats Batch Script setup and to Grid Lines. This is to support additional coordinate system functionality.
• Added QVC Models to "Import Vector" file filter.
• Merge Models should now preserve added QTA features like AGL.

What's New for Quick Terrain Modeler Version 7.1.4

Quick Terrain Modeler v7.1.4 adds the most comprehensive user interface overhaul in our product's history. The most obvious changes will be in the addition of a Layer Tree, an interactive Mini-Map, and new button icons on the button bar. These changes will make it much easier to interact with all the model, vector, texture, and marker layers and to intuitively understand what data is available in the workspace. In addition to these items, there are significant changes to Markers, enabling individual display options and the addition of imagery/user defined symbology to the marker display, tools to temporarily crop the view to a subset of the model, and bookmarks to let you return repeatedly to the same view. Here are the details:

Layer Tree

The purpose of the layer tree is to make it very clear what geospatial elements are loaded into the 3D scene, and to enable easy user operation on these elements. There are many options to left click and right click on each element to expose frequently used tools and actions and left/right click on section headers to expose other commonly used functions for the entire category. The categories are Special Overlays, Models, Textures, Vectors, Markers, Routes, and Bookmarks.

Interactive Mini-Map:

The Mini Map is a static image of the loaded models, vectors, and markers that dynamically displays the view extents as a white vector. Users can change the appearance and use it as a tool to interactively zoom to specific features by double clicking and/or right click/dragging a zoom polygon in the mini map.

Markers:

Markers have been radically upgraded. Users can now have individual markers displayed differently (in the past all markers had to be displayed in the same style). In addition, there are tools to add an image to the marker, enabling an infinite range of possibilities for adding symbology or any other raster effect.

New Point Size Options:

There are modifications available to smooth out the voxel point autosize rendering algorithm for point clouds. Checking the new "antialiasing" checkbox in the point size option window will do two things: 1.) Eliminate the visible "bands" between voxel points of different sizes and 2.) make the point cloud points round instead of square. This requires a moderately new graphics card to work efficiently. This will be the default point rendering mode unless QT Modeler detects the absence of suitable OpenGL version.

Temporary Cutting Cropping:

You can now right-click on the cut/crop buttons to generate cut/crop filters. These are texture layers that hide the points in questions without throwing away points. So visually it's like instant cut/crop/undo.

Buttons and Button Bar:

The Tool Bar has been completely revamped for Version 7.1.4. In addition to all new button icons, there are also new functions that have a button (e.g., HLZ map, slope analysis, grid lines, batch scripting, etc.), we have also added the ability to customize the tool bar in any way you choose. Go to the File Menu > Options and Settings > Configure Tool Bar.

Bookmarks:

Bookmarks take the place of the old Save/Load View/Position. Think of bookmarks in much the same way as you would bookmarks in your internet browser. Bookmarks will always take you back to the same camera position and view, regardless of what data is loaded (i.e., they are not model or data-dependent). Bookmarks will also appear on the Layer Tree to easily return to a given view. Bookmarks can be shared among users.

Scale Bar

Added scale bar when in 2D mode. Just toggle to 2D mode and the scale bar will appear in the lower right hand corner. It is almost impossible to make a meaningful scale bar in 3D mode, due to the perspective/parallax associated with 3D viewing, so a 2D scale bar acknowledges all the user requests we have received for this tool.

Status Bar Options

There is now a "Status Bar Options" dialog. Either in the "Display->Options" menu or by right-clicking on the status bar. Here you can select:

1) What coordinate system to use when displaying the cursor coordinate (e.g., display MGRS even if the data is in UTM)

2) Whether to show the range from the camera to the cursor position.

New Hot Keys/Shortcuts:

• "Q" Creates Bookmark
• Click "V" to start a vector line, then "V" to end it. The result will be a straight vector line in the default style.
• Click "S" to start a mensuration line, then "V" to end it. The result will be a permanent vector line in the "mensuration" style. Very useful for labeling HLZ's.

Tweaks

• If you open multiple files, and one causes an error, QT will now still open the rest and just tell you at the end which files it couldn't open.
• The "Add Models" function should now better respond to the "cancel" button.
• QTT Importer now scans and corrects for bad NAN values and out-of-range data ( > 1e20, < -1e20)
• GridStats GUI now has separate "OK" and "Cancel" buttons. The difference is that "Cancel" also removes the Texture Image.
• Tweaked "shift-select" point selection a bit. Now should do a better job of detecting which point is directly underneath the cursor.
• QTT Import has some sanity checking on NAN values - if no NAN is embedded in the import file, but the minimum Z comes in exactly equal to -32767.0, -9999.0, or -FLT_MAX then that value will be treated as "NODATA". This will be helpful in loading some DoD-generated DEM files.
• Route Editor can now remove last Route.
• Switched all models over to double precision view frustum
• Added "copy files" function to Model Search.
• Mensuration Export should default to "Mensuration style".
• Image search should now be able to find images that have "no data" fields defined (These were formerly mis-identified as DEMs).
• Image search will now find CADRG/CIB/RPF images during image search and image loading.
• Hidden models should no longer affect GUI responsiveness calculations.
• You can now turn on OpenGL Antialiasing ("Display->Options"). This engages OpenGL's native point/line/polygon anti-aliasing. The most immediately obvious effect is that point-cloud points appear as circles rather than squares. This may or may not have a meaningful performance impact depending upon your video hardware.
• If you draw a vector by starting and ending with 'v' it works like it always did. If you start with 's' like you were doing a mensuration line, and then end with 'v', you get a "permanent mensuration line" style vector.
• Added anti-aliasing check to point appearance dialog.
• LAS georegistration interpretation should be smarter when given ambiguous geokeys (e.g., geodetic data that was tagged as Geodetic with both GeoLinearMeters and GeoAngularDegrees).
• Water Level Contours now generated by same code as other Contours.
• Sentinel Builds should be more informative when failing.
  

Bug Fixes

• Fixed: Issue tallying return numbers when exporting LAS from QTA LAS.
• Fixed: Issue sampling height after loading vector file.
• Creating an LOS Map will no longer clear the colors of other loaded point clouds.
• Markers set to "Fixed Size in Pixels" will behave properly in 2D mode.
• Fixed some issues with RGB handling on LAS Open/Add
• Switching between 2D/3D will no longer reset which models are visible.
• Fixed issue with export of multiple files to LAS with RGB.
• Fixed issue with QT Reader importing multiple RGBLAS files.
• Fixed an issue with "Export Outline to GE"
• Fixed broken print button
• Fixed Issue reading LAS files where the first point starts with the 0xCCDD header end code.
• Fixed issue with resizing window resetting model visibility.
• Fixed code reading Geokeys from LAS so that it handles odd cases like my sample MD State Planes data while still properly handling custom data sets like our NJ State Planes data.
• Fixed "surface normals" check when importing XYZ Ascii/LAS/FXYZ->QTC/QTA.
• Fixed some issues with Minimap and certain ATI Mobility and Intel video cards.
• Fixed an issue where hidden models which were not drawn to full LOD the last frame before they were "hidden" prevent QT from fully resolving.
• Vector Models should no longer confuse Water/Volume calculations.
• Fixed another precision issue with INI files/Batch Scripts and data in Geodetic meters.
• Fixed bug where Marker editor could get confused about which marker it was editing if you pressed "enter" in the "rename" field.
• Fixed issue with reversed vector arrows.
• Fixed issue where render progress bar didn't always go away.
• Fixed memory leak in "Are you sure you want to close QT?" dialog.
• Fixed issue where last point in a point cloud row was not always rendered when zoomed in.
• Fixed issue with meter-scale import of geodetic data through batch scripting.
• Fixed some issues with direction of vector arrows.
• Fixed memory leak in "Are you sure you want to close QT?" dialog.
• Fixed memory overrun in water level contours.
• Fixed import of KML to Vector
• Fixed bug using legacy triangulation together with "smooth interpolation".
• Fixed hang bug doing "smooth interpolation", legacy triangulation with RGB.
• Fixed issue with QT not properly closing out Sentinel license on shutdown.

Quick Terrain Modeler v7.1.3 is Available

New v7.1.3 Features:
Quick Terrain Modeler adds significant new capabilities that range from a very fast indexing tool that allows users to quickly inventory and visually display their geospatial holdings, to an image registration tool that assists in accurately placing poorly registered (or unregistered) imagery on top of a 3D scene. Here is a summary of the new capabilities:

Indexing Tool
The purpose of the new indexing tool is to quickly catalog LiDAR and imagery holdings and export the catalog to KML, SHP, or CSV file. It can be found in the Export Menu. Simply open the index tool, specify a directory, drive, or external storage device, and let QTM do the rest. Export options include KML/KMZ, SHP, and/or CSV file and can be organized by existing directory structure or by file type. The resulting product is a group of vectors that represent the coverage of your LiDAR and imagery holdings. It is a very fast tool that lets you easily understand the extents and coverage of your holdings by visually interacting with them in Google Earth or ArcMap.

Image Registration Tool:
The purpose of the image registration tool is to give users a powerful, interactive tool to register imagery to elevation data. The new interface is accessible from a button on the "Overlay Orthorectified Textures" interface, which is accessed either from the textures menu or from the "Overlay Orthorectified Textures" button. The steps are fairly simple: Load a model, select an unregistered (or poorly registered) image, create a few tie points, and snap the image into place.

Vector Annotation:
Vector annotation uses the existing measurement line tool to create vector lines which remain in the model to point out and delineate features and areas of interest. Annotation vectors can be created several ways:

• After placing a mensuration line, use the "Vector Export" pull-down to select either a point to point vector or a sampled vector.
• While placing a mensuration line, type "V" to end the line. This will create a sampled (i.e., terrain-hugging) vector.
• While placing a mensuration line, type "SHIFT-V" to end the line. This will create an unsampled (i.e., point to point) vector.
• Use the "Configure Vector Models" tool in the Display menu to change the color and thickness, changed to dashed/dotted, and/or add arrowheads.

Range Rings:
Range rings enable a very simple visualization of distances from a given point. Range rings are user-configurable, with choices that are optimized for both DEM's and point clouds.

New File Formats:
Open/Import: IMG DEM
Export: IMG/IGE (this will support export of DEM's greater than 4GB in size), USGS DEM

New Hot Keys:
• N: Move Model to a north-up, nadir view (i.e., viewing straight down the Z axis), centering the view on the location that was already in the center of the view.
• SHIFT-N: Holding down SHIFT causes a red box to appear. Typing "N" causes QTM to go to a north up nadir view as noted above, but with the red box at the center. Left clicking will pull up the point interrogation window.
• Double Click: Move cursor anywhere, double click to bring the point under the cursor to the center of the view. Orientation and zoom will be preserved (i.e., it will not necessarily be a north-up, nadir view.)
• K: Hold down "K", move cursor to the vicinity of an existing marker, then left click and drag to move the marker.
• V: Create a sampled (i.e., terrain hugging) vector by typing "V" to end a mensuration line. Remember to set default vector display properties in the Display > Configure Vector Models menu.
• SHIFT-V: Create an unsampled (i.e., point to point) vector by typing "SHIFT-V" a mensuration line. Remember to set default vector display properties in the Display > Configure Vector Models menu.

Route Editor/GPS Export Upgrades:
Version 7.1.3 adds significant capabilities in custom route creation/editing, exporting routes and waypoints to handheld GPS units, and exporting georegistered images as custom maps to Garmin GPS devices. Some of the highlights:
Route Editor:

• Added buttons to move all markers from the "Markers" list to the "Route" list and vice versa. You no longer need to double click each marker to add it to the route.
• Added a "Reverse Order" button to quickly flip the order of the markers in the route.
• Added a "Rename" button that quickly renames and renumbers all markers in a route. For example, a route marker list of Marker1 through Marker20 can be reversed in sequence and renamed CP20 through CP1 with 2 button clicks.
• Only visible markers will be exported as part of the route, so there is a new "Show/Hide Markers" button on the Route interface that allows quick access to that function.
• The ground distance of the route as well as the terrain profile of the route can be seen in the "View as Mensuration" window.

Exporting Georegistered Imagery to Garmin GPS: The "Render Screen to Registered Image" function in the Export menu now exports georegistered screen grabs as JPG/KMZ in exactly the format that Garmin GPS devices need to use the images as a "Custom Map". This will make chipping images and sending them to Garmin GPS very fast and simple. The Garmin is still subject to a maximum 3MB image size, but this can be achieved by reducing QT Modeler's window size.

New Triangulation Interpolation Methodologies for DEM Creation and Editing:
Version 7.1.3 adds significant new capability in DEM generation and editing. One of the most helpful new features is the implementation of a "Natural Neighbor" smoothing algorithm that can more gracefully and intelligently fill holes in coverage. This new fill method will be particularly useful in rugged terrain and could also be helpful in filling holes in existing surface models (e.g., DTED's).

• Added "Snap Increment" to Gridding Options. This sets the amount to which the grid edge is rounded off.
• Most fill methods make a final simple interpolation pass along the edges of the DEM to try to fill in single-bin-width empty edges.

Model/Image Search Upgrades:
In recognition of the fact that searching for LiDAR data and associated imagery takes an inordinately large amount of many users' time, QTM version 7.1.3 implements a search caching tool that can vastly accelerate searches.

• To create a cache, open a search window, select a directory, and press "generate cache". This establishes a baseline for data and imagery contained in that folder and all subfolders.
• To search from a cache, press "Select Cache", and select the cache file, then proceed as normal
• To search from a directory (i.e., the "old" way), press "Select Directory", and select the directory, then proceed as normal

Quick Terrain Reader Upgrades:

• Quick Terrain Reader v7.1.3 natively opens LAS files and NITF-wrapped LAS files (i.e., NGA's .ntf LAS files)
• Quick Terrain Reader will now display RGB values when opening LAS files that have RGB color values embedded.
  

Tweaks
• Added "Clear colors in area" to selection area context menu. This will assist in raster cleanup of analysis results.
• AGL Alpha Clipping shows scale in meters rather than in the 0-255 (8-bits) range.
• If you attempt to edit an attribute of a marker that does not have that attribute, the markers will be given default attributes to match the table.
• Tweaked folder selection dialog to fix Windows7 issue.
• Added a "Clear Black" button to texture editors, to enable users to make black border regions invisible.

• Moving speed in "flight mode" should no longer slow down nearly so much when close to the model.
• Closing "Edit Texture" window should no longer delete the texture.
• Added "GEOTIFF Export Option" for forcing noData colors to black and real data which is black (0,0,0) to (1,0,0).
• Flex version now falls back to Sentinel Floating
• File Preview window should show more info about GDAL files
• Models should be able to handle up to 100,000 point cut/crop/export selection operations

Quick Terrain Modeler v7.1.2 Released

What's New for v7.1.2:

Quick Terrain Modeler Version 7.1.2 makes DEM creation faster and more flexible, supports emerging DoD LAS file formats, greatly enhances Google Earth functionality (especially in QTM 64-bit), and adds tools to assist the tactical user workflow. Please see more detailed descriptions below or download the "What's New for QTM v7.1.2" PDF.

New v7.1.2 Features:

New Tools for QTT (DEM) Creation

QTM's new DEM creation tools not only accelerate the DEM creation process, but also provide significant additional flexibility in how these DEM's are created. The primary enhancements are support for non-triangulated methodologies. Non-triangulated methodologies essentially establish a grid first (e.g., a user-specified 1-meter grid), then uses a statistical choice (e.g., maximum Z-value in each grid cell) to establish the elevation for that cell. When this process is completed for all grid cells, QTM will assemble the resulting array of elevation values into a continuous 3D surface model in QTM's QTT format. Different methodologies will achieve different results.

New DEM Creation Methodologies:

• Non-triangulated with no "hole fill": Requires no triangulation (i.e., is faster) and does not fill in "holes" where data is missing.
• Non-triangulated with simple interpolation "hole fill": Requires no triangulation (i.e., is faster) and fills in "holes" that are one grid cell (aka "bin" or "pixel") in size.
• Adaptive Triangulation: Requires no triangulation where data is dense and continuous, but fills in holes based on user-set preferences where there is no data.
• Legacy Triangulation: The way QTM has always built DEM's remains unchanged.
• User-settable statistical basis for DEM creation based on Min Z, Max Z, Mean Z, or Max I of the LAS points in a given grid cell. This offers a great deal of flexibility to ignore "spikes" in data and to create a DEM that reflects the user's needs.

Data Previewer

When selecting files to import or open, QTM will now preview file header information and interactively display the footprint of the file in Google Earth. Supports both 3D and 2D file formats (i.e., DEM's and imagery).

• Preview 3D point and DEM formats: LAS, NITF/LAS, GeoTIFF DEM, BPF, QTT, QTC, and other 3D formats supported by GDAL.
• Preview 2D Raster formats: GeoTIFF, MRSID, NITF, IMG, ECW, and many other formats.
• Preview Vector Formats: SHP, KML, DXF, etc.

Route Editor

High resolution terrain data provides an unprecedented ability to understand terrain features and plan walking or driving routes accordingly. For example, 1 meter resolution DEM's permit users to see hazardous terrain (e.g., very steep terrain/cliffs) that may not be obvious on contour maps or in lower resolution 3D terrain models (e.g., DTED). Route editor permits users to string together Markers into a sequential route, look at route terrain profiles, and export routes/waypoints to GPX directly onto handheld GPS devices. Furthermore, routes can be complemented by using other existing analytical tools such as slope/mobility analysis, line of sight analysis, and/or HLZ analysis. This new tool is in the Markers Menu.

• Place markers normally. Use markers to indicate route around hazardous terrain, optimize visibility, and/or mark features of interest.
• Organize markers into sequential routes and/or waypoints.
• Save/load routes as a "Mission"
• Export routes to various vector formats - GPX, SHP, KML
• Save GPX files directly onto handheld GPS devices (e.g., Garmin Colorado, Garmin Foretrex 401, etc.)

Modified Helicopter Landing Zone Tool

Added a new category of result - "HLZ Fringe" that adds the HLZ radius back into the result. This will avoid "single pixel" results being displayed.

Set Obstruction ("Delta Z") tolerance default to one foot (rather than 1 meter). This value is still user settable, but the one meter default value proved to be too large.

Raster Editor (see below) can edit/customize HLZ results.

Real Time Contours

Visualizing contour lines on top of DEM's can be a very useful tool for gaining an intuitive understanding of the terrain, particularly if the user is accustomed to looking at 2D topo maps. Users can create and modify contours instantaneously for display purposes. Simply press the new "Real Time Contours" button to display contour lines. Right clicking on the button calls up the contour configuration interface. Use the slider bar to instantly reconfigure contour line spacing. This new tool works on surface models only (QTT, DEM, etc.).

Google Earth Support

QTM has interacted with Google Earth in many ways - export of vectors, rasters, markers, model outlines, and synchronization of QTM views. Prior to version 7.1.2, however, QTM view synchronization was not possible in the 64-bit version. In this release, not only has X64 synchronization been added, but significant new tools using Google Earth capabilities have been added. The key v7.1.2 Google Earth enhancements:

• QTM X64 now synchronizes the view with Google Earth both on a one time basis (Type "G" on the keyboard) or on a continuous basis (Control Menu…Control Mode > Synchronize Google Earth). Synchronization has not functionally changed in the 32-bit version, but the v7.1.2 implementation may require the user to adjust the navigation speed in Google Earth (Tools...Options...Fly-to Speed)
• QTM can now export QTTs to KMZ SuperOverlay (Intensity, RGB, or Height). A Super Overlay is an image "pyramid" that makes it very easy for Google Earth to manage huge images. Because the Super Overlay is pre-processed, Google Earth will not need to perform downsampling of very large images and georegistration will be much more accurate.
• File Open and File Import windows now offer the option to display the file extents in Google Earth prior to opening the file. 

New LAS Import Tools
Since LAS has finally become the overwhelming file standard for storage and exchange of LiDAR point data, Applied Imagery's efforts to enhance import and analysis tools have become very focused on LAS. To this end, v7.1..2 offers new tools and capabilities associated with LAS files:

• LAS header preview in File Selection windows (i.e., see header information prior to loading and/or importing).
• New LAS import window that accelerates import of LAS data by choosing to "trust" that the LAS header information is correct (i.e., avoiding a verification step) and provides access to a LAS header preview window.
• Support for NGA's NITF LAS Files and LAS Variable Length Records (VLR's) in LAS Header. LAS files that are wrapped in NITF are now supported as follows:
• QT Modeler will import NITF LAS files the same way non-NITF LAS files are imported (i.e., it will be transparent to the user)
• QT Modeler will also be able to search NITF LAS files spatially, just as normal LAS files are searched.
• NGA VLR implementation will not impact import.
• Ability to override geokeys upon export to LAS files.

Override Geokeys Upon Export

If models were imported as "Cartesian" or if the georegistration values were incorrect, users now have a mechanism to override the existing geokey values. For example, if users imported LiDAR data in State Plane coordinate system as "Cartesian" in QTM, all exported products that use geokeys (LAS and GeoTIFF products) will now be correctly labeled. Users will have the flexibility to include coordinate system, vertical datum, horizontal units and vertical units in the exported geokeys.

Raster Editor:

Edit analysis results by using selection areas to manually recolor raster result displays. The primary use for this is for HLZ and Line of Sight analysis. Users can now manually remove results to bring additional focus into areas of interest or areas that may prove to be distractions. For example, performing HLZ analysis could generate 10 candidate HLZ's. The analyst may want to focus on only three of the HLZ's in an exported briefing, so the raster editor will enable recoloring all results except the three suitable HLZ's to avoid downstream user confusion.

Flex Licensing:

QT Modeler FlexNet licenses will now have the option to fall back to Sentinel floating licenses.

Multithreading:

Version 7.1.2 has implemented multithreading in several operations, thus taking advantage of multi-core processors to accelerate CPU-intensive operations.

• Routines to populate QTC from QTA are now threaded and better optimized.
• Threaded LOS Algorithm.
• Threaded QTT normal generation.
• Threaded building of point cloud LOD trees.
• Vector generation and consolidation.
• Explicit "Core Limiter" tool to control how many CPU cores are simultaneously working on QT Modeler processes. This will avoid having QTM multithreaded tasks consume an entire multicore CPU, preserving CPU cycyles for other tasks. (File Menu...Options/Settings...Memory Management Options)

Vector Support:

QT Modeler now does Vector Import through GDAL/OGR. This enables coordinate system recognition and support for any vector format understood by GDAL. Any Vector model in QT can now be exported to KML, DXF, or SHP. This will include georegistration tags where possible.

Support Enhancements

Once click access to log file and INI files (File Menu...Options/Settings...Open QT Files Directory)

Bug Fixes/Tweaks:

• Tweak: Export Markers to ASCII now includes UTM Zone.
• Tweak: Added 2D and 3D options for mensuration export to vector.
• Tweak: Export to PPT will use PNG instead of TIFF, making PPT presentations dramatically smaller in size versus the TIFF export of previous releases.

Quick Terrain Modeler v7.1.1 Released

What's New for v7.1.1:

Version 7.1.1 adds marker sorting and inspection tools that enable the import of multi-attributed markers, sorting/display by any marker attribute, and new ways to methodically visualize, inspect, edit, and export markers. These new marker enhancements will not only enable markers as a large scale QA/QC tool, but also enable more tactical users to methodically inspect their points of interest.

In addition to marker upgrades, v7.1.1 introduces tools to make Grid Referenced Graphic (GRG) creation extremely fast, easy, flexible, and intuitive. The new GRG tools include more precise label tagging/placement, more flexible display options for marker tags, generic MGRS grid labeling (e.g., A-Z alphabetic rows, 1- N numeric columns), limiting MGRS grid creation to the current view (i.e., ability to grid smaller areas of interest at a denser grid spacing), and the ability to export entire GRG's (GeoTIFF, TIFF, or PowerPoint) or components of the GRG (3D sampled grids as KML or SHP, tags as KML points or SHP). These tools enable a new world of 3D GRG's, in which user can create GRG's on 3D DEM's and point clouds, interact with them in 2D or 3D, perform analysis on the fly (line of sight, HLZ, mobility, etc), overlay imagery, and export georeferenced products to other applications.

Version 7.1.1 also introduces tools for indexing model and image search results in KML. After a user spatially searches (e.g., based on an MGRS or UTM coordinate) for data or imagery using the model or image search tools, QTM v7.1.1 will permit a quick KML index export. There are also a number of tweaks, optimizations, and bug fixes noted below.

New v7.1.1 Features:

Marker Upgrades:

The biggest new features for v7.1.1 are marker sorting/display/inspection tools. These new tools permit a wide variety of sorting, display, and editing of markers, either by their spatial properties or by their attribute values. They also enable using markers as a QA/QC workflow tool. The user will be able to import markers from a CSV file (at this time, an ASCII CSV file is the only way to import markers with attributes - more to come), along with an unlimited number of attributes per marker. The user can then sort the markers on any criteria, then progress through the list of sorted markers one by one to inspect the location around the marker. QT Modeler will advance the view to that area of the model, enabling a rapid QA process.

The marker Show/Hide interface now has a spreadsheet-style look that enables the following:

• Sort markers by any attribute.
• Edit marker attributes in a table.
• Right-click context menu on Show/Hide Markers to access editing and other functions.

Similar to the spreadsheet-style Show/Hide markers interface, there is a separate interface for "Inspect Markers" which enables:

• Methodical one-by-one inspection of markers, with a checkbox scheme to track markers that have been inspected already.
• Automatic advancing of the view to the next marker.
• Inspector initials to track the user who has inspected the markers.
• Google Earth Synchronization upon marker advance (i.e., use Google Earth as a complementary inspection tool).
• One-click saving of edited marker CSV file.

Other marker enhancements:

• Optimized rendering mode for markers to speed rendering of large numbers of markers.
• Added option to Hide marker Pins (just show text).
• Marker display options now display only markers that correspond (in X-Y) to loaded data.
• If "No Marker Pin" is selected, marker billboard will be centered on the pin position, making placement of tags and GRG creation much more user-friendly.
• Marker Export to KML will now include marker attributes (if marker attributes are attached to marker)
• Added Option for "Mouseover Billboards" - i.e., only show marker "Billboards" if your mouse hovers over it.

Indexing Tools:

When performing model or image search, users can now quickly export a KML index of the search results. Users can either export the entire list of search results, or select individual models/images to export as a KML index. This new capability enables quick cataloging of model/image search results in KML format:

• Added KML Export from Model Search.
• Added KML Export from Texture Search.
  

Mobility Analysis:

There is a new palette in the slope analysis tool (Analysis Menu...Analysis Tools...Slope Map) that makes basic mobility analysis very simple. The palette will color the terrain in three bands: 0-5 degrees green, 5-15 degrees yellow, over 15 degrees red. If different mobility/slope break points are required, the same palette customization tools exist to create and save custom palettes.

Grid Lines/GRG Creation:

Added new capabilities to the "Generate Grid Lines" tools. These tools will make the creation of Grid Reference Graphics ("GRG's") much more flexible and customizable.

• Generic Grid Creation (A-Z alphabetic rows, 1- N numeric columns)
• Limit Grid Creation to view area (i.e., create a "chip" of an MGRS grid over an area of interest).
• Export entire GRG as a TIFF, GeoTIFF, or PowerPoint Slide
• Export components of GRG's in a variety of georeferenced raster and vector formats.

Bug Fixes/Tweaks:

• Tweak: Added lighting "Default" button that resets lighting intensity/direction to default settings.
• Tweak: Raster LOS will set Vector LOS traveler/Observer heights to match.
• Tweak: Optimized image overlay for NITF. Added "Smart Contrast Enhancement" check to Image Importer. If >75% of the pixels are black (less than 20% intensity) after importing an image then QT will automatically enhance the image (if the Smart Contrast toggle is checked).
• Tweak: Optimized and sped up QTT rendering in "No Smoothing" mode.
• Tweak: Updated FlexNet licensing to support SPARC/Solaris servers.
• Tweak: Optimized polygon selection
• Tweak: Hitting "Escape" will now cancel a mensuration instead of popping an empty box.
• Tweak: Updated to latest PointSet code.
• Tweak: QTA "Quick Colors" menu options will now inform the user they do nothing if they are selected when no QTA models are loaded.
• Tweak: Export selection area to SHP now preserves Z values.
• Tweak: Loading a KML automatically loads points as Markers.
• Tweak: Profile Window no longer draws line-segment dividers if the line contains more than 30 segments.
• Tweak: Marker import from ASCII dialog should now remember "Interpolate from Z" setting.
• Fixed issue in which QT dropped into a less accurate floating point precision mode after doing anything involving triangulation (mensuration profiles or QTT generation). This was the most significant bug in v7.1.0.
• Fixed Model Search radius, which was always using "100" regardless of the value the user entered.
• Fixed import issue in which crop to area was being ignored.
• Fixed initial path for Model Search.
• Fixed progress bar in Model Search.
• Fixed issue setting AGL boundaries after AGL Analyst.
• Fixed issue with autoscaling intensity/rgb/alpha in QTA.
• Fixed crash bug in save models menu.
• Fixed issue where generating a QTC from a QTA could drop a few points near the edges due to roundoff error.
• Fixed some potential inconsistencies in the way QT remembers dialog settings.
• Fixed issue rendering QTT triangles near "No Data" areas with "Smoothing" off.
• Fixed: Removed non-compliant spaces from KML export.
• Fixed issue exporting Mensuration to SHP and converting coordinate system.
• Fixed issue where SHP files could interfere with proper rendering.
• Fixed export of Screen Selection to SHP and KML.
• Fixed a bug properly handling extremely large NAN values.
• Fixed odd issue where QTA Quick Color wouldn't run properly the very first time you ran it after closing the "About Models" window.
• Fixed issues with QTA positional stat queries (Area Stats and Grid Stats).
• Fixed small offset of crosshairs.
• Fixed issue where sometimes Marker Billboards turned gray.
• Fixed LAS 1.3 interpretation of Time codes.
• Fixed issue importing to UTM feet when UTM feet was specified in the LAS header.

Quick Terrain Modeler v7.0.3 Released

What's New for Quick Terrain Modeler Version 7.0.3

Version 7.0.3 offers two significant new tools (direct export to PowerPoint and Model Finder), a significant reworking of the show/hide models interface, a fix for the v7.0.2 slow rendering problem (large point clouds), and a handful of optimizations for shortening production timelines and working with huge data sets. As always, we appreciate the feedback and insight you provide us.

New Features:

Model Finder:
Model Finder offers the user a very fast way to locate and load relevant data. Users simply input a coordinate, point to a directory, and QTM quickly finds and displays a list of models and data sets that contain that coordinate. The user then clicks on a list of data/models to begin using that data. Users can input UTM, MGRS, or Lat/Long coordinates to search for data, even if the data sets are in UTM. Coordinate conversion for model search does not apply to Cartesian/State Plane data. This tool will eliminate the time consuming task of manually searching for relevant data sets among long lists of ambiguously named tiles. Search applies not only to our native QTT and QTC files, but also to GeoTIFF DEM, LAS, DTED, SRTM, and shapefiles.

Direct Export to PowerPoint: Quickly build PowerPoint briefings by directly exporting QTM screen grabs, titles, captions, orientation axes (North arrow), and legends to PowerPoint slides. This tool also enables a "permanent burn" of classification level or other text into the exported images and the ability to save specific view parameters to return to later (i.e., a 3D bookmark).

Show/Hide Model and Flicker Tools: Version 7.0.3 adds an extremely flexible way to display subsets of models when multiple models are loaded. The new tools permits an automated "flicker" of models and a way to group models together while performing automated or manual flicker. The intent is to customize the flicker to any situation and enable model manipulation (rotate, zoom, etc.) while models flicker. This assists the human eye in discerning changes in terrain, differences between models, and anomalies in data. This tool will be very useful not only production environments for data Quality Assurance and Quality Control (QA/QC), but also in operational settings where noticing slight differences in point clouds or DEM's can be very useful.

Mensuration Line : After finishing placement of a mensuration line, the distance display now remains visible (in previous version it stopped being displayed when the mensuration window popped up). Because the mensuration line display will give a better sense of scale, this will be particularly useful in the export of unregistered imagery (i.e., oblique screen grabs). It will also be useful in conjunction with the PowerPoint Tool and briefing creation.

Quick Terrain Reader Upgrades: Per recommendations from our DoD customers, the free Quick Terrain Reader will now convert and display coordinates between UTM/MGRS/Geodetic. The primary purpose was to enable the display of MGRS position coordinates in the status bar when QT Reader users loaded UTM data (e.g., BuckEye). In addition, Quick Terrain Reader now has the ability to overlay MGRS grid lines on models.

Bug Fixes/Tweaks:

Quick Terrain Modeler v7.0.0 Released

QTA Attribute Tables - Working with Point-Level Attributes:
QTA is a new data structure that establishes an attribute table/index when importing QTC point clouds. These attributes are typically the point data record attributes of an LAS file, but can also be imported from attribute columns of an ASCII file. Because Quick Terrain Modeler can now access all attribute values on a per-point basis, the QTA structure enables the following functions:

• Query of all attribute values (e.g., intensity, return number, classification, etc.) for a single point.
• Custom coloration based on attribute values (e.g., color points by return number, classification value, scan angle, etc.)
• Filtering point clouds based on attribute values.
• Performing grid statistics on specific attribute values.
• Placing any attribute in the Z-axis, essentially replacing elevation with another property of the data.
• Writing LAS files with fully populated point data record values.

Proxy Mode: Working with Enormous Files:
Proxy mode is a new tool that enables working with data sets that, from a practical perspective, are unlimited in size. Proxy mode uses the QTA structure to create an index that connects a large source data file to a decimated point cloud. While only a portion of the points are being displayed, analysis functions are performed on the entire source data set.

Batch Scripting:
Batch scripting allows the user to create customized scripts to automate repetitive tasks. The initial functions that can be scripted are import, save, convert model to UTM, and a variety of export formats.

Point to Point Line of Sight:
This new Line of Sight (LOS) tool enables detailed terrain and visibility analysis between observers/targets in a terrain. It not only provides an instantaneous yes/no answer to visibility questions, but also provides a terrain profile, distances, changes in elevation, and angle of inclination between terrain positions. (USA Version Only)

Import Merged GeoTIFF DEM's:
This function was implemented for DoD users who wanted to load multiple large GeoTIFF DEM files, but were constrained by memory limitations. Importing merged and/or downsampled GeoTIFF DEM's enables users to work with significantly larger areas of interest.

Undo Function:
Added an "Undo" function that will undo the last cut or crop operation.

AGL Analyst:
AGL Analyst now works on QTT Models (DEM's).

Customized ASCII Export Configuration:
This tool allows users to set the number of decimal places as well as the column order for data exported as an ASCII text file. This will enable setting appropriate levels of precision, thus minimizing ASCII text file sizes by simply minimizing the number of ASCII characters written.

HTML Help:
QTM help files are now HTML help. This will enable using help files in Vista.

Sentinel Keys & Floating Licenses:
Quick Terrain Modeler will now be able to access multiple keys from the same Sentinel server, thus giving flexibility to the enterprise QTM deployment architecture.

AGL/Alpha Clipping:
Added ability to manually set slider range for GL Clip.
Added ability to copy intensity into alpha.

Revamped Clipping Planes:
Users can now implement six simultaneous clipping planes: above and below user specified X, Y, and Z values.

Markers:
Increased range of marker size slider as well as improved interactivity with shape files.

Mensuration/Profiles:
Added numerous tools to make measurements and profiles easier and more intuitive for both point clouds and DEM's,

Convert Model:
Added ability to convert QTC Models between Geodetic and UTM.

Quick Terrain Modeler v6.1.2 Released

Quick Terrain Modeler V6.1.2 adds several new tools that continue to make exploitation of point clouds easier, faster, and more intuitive. Between the existing grid statistics tool, the new AGL Analyst tool, and the new point cloud "slicing and stepping" capability, users can choose to visualize and isolate points spatially (by absolute elevation, by AGL height, by selection area, or by profile "slice") and/or statistically. These capabilities enhance the user's understanding of the point cloud data, regardless of whether the intended use is for Quality Assurance (QA), earth science, forestry, feature identification (on a surface or under the canopy), vertical object (VO) identification, or mission planning. Applied Imagery's goal is to make visualization, analysis, and exploitation of LiDAR data powerful, flexible, intuitive, and simple. Many of our tools are based on user feedback, so thank you and please continue to provide feedback and suggestions.

Also, please do not forget that, as of version 6.1.0, all of these tools are now available in both 32-bit and 64-bit versions.

Version 6.1.2 New Features:

AGL Analyst (Analysis Menu)

Because many users would rather work with relative, Above Ground Level (AGL) heights rather than absolute elevations, Quick Terrain Modeler Version 6.1.2 introduces a powerful tool called AGL (Above Ground Level) Analyst. Some of the most common reasons for wanting to work in AGL space are to measure tree and roof heights, to measure the height of potential vertical obstructions (VO's), and to selectively remove vegetation and canopy from a point cloud, thus enabling the user to see and identify objects under foliage or other obstructions. This tool calculates and assigns an AGL elevation value, in addition to an absolute elevation value, to every point in a point cloud or every vertex in a surface model. The simple steps of AGL Analyst are as follows:

• Calculate AGL heights of every point either by comparing to a bare earth model (if available) or by quickly estimating a ground surface.
• Once AGL Values are calculated, apply a color scheme based on AGL heights, rather than absolute heights.
• Exploit the AGL model by querying points for their AGL heights, clipping data based on height AGL (i.e., temporarily removing points based on their heights above ground), and swapping the AGL elevation values with the absolute elevation values, and displaying an AGL height legend.
• Since Alpha Filtering (Analysis Menu) is the mechanism for clipping by AGL, the alpha filtering interface has been modified to offer more options in filtering based on alpha (i.e., AGL heights). Users can now enter values manually or filter "equal to" specific values.
• Export products such as the 3D ground estimate, an ASCII file of the AGL points, and point clouds edited by AGL values.

Point Cloud Profiles – "Slicing and Stepping" (Mensuration Profile Window)

Version 6.1.2 adds the ability to quickly move a "scatter plot" profile area through a point cloud. This tool will aid in quickly identifying features and terrain characteristics in a point cloud that may be obscured by returns from foliage. The user simply takes a "slice" of the point cloud, views it in profile, and "steps" through the model based on that slice.

Markers (Marker Menu)

Based on user feedback, markers have been significantly enhanced in Version 6.1.2. The upgrades are as follows:

• Much more comprehensive "Marker Options" menu (Markers Menu) that enables the setting of most marker display options from a single interface.
• Marker "Billboards" which enable the display of a larger amount of text (i.e., more than the existing "Marker Name" text) on a white background. Billboards will enable detailed descriptions of features and locations.
• Marker position in label. Users can now choose to have the marker X-Y location displayed in the marker name or billboard. The display can be in coordinates of UTM, Geodetic, MGRS, or Cartesian.

Grid Stats (Analysis Menu/Grid Stats Button)

• Grid stats now counts empty cells in the "Number of Points" and "Density" calculations and export products. This enables the use of "Number of Points" in Quality Assurance (QA) workflows.
• Added legend support for Grid Stat calculation displays. The legend will now display the statistic calculated, the color range, and the range values.
• Added the ability to export an ASCII file with the parameters X, Y, Z, "Stat", where stat is the numerical result of a statistical calculation. Every point in a point cloud will be exported with its associated statistical value.
• Added the ability to "force" grid stat results into vertex colors in cases where the resulting texture is too large for the user's video card. Forcing the results into vertex colors consumes RAM, not video memory.

Orbit Mode (Keyboard)

Users can make a model continuously orbit about its center by simply typing "O" (i.e., Orbit) on the keyboard. This is the only control mode in which the model continues to "move" without direct user intervention. It may be helpful for briefings as well as AVI movie creation.

TIFF Export Text Template (Export Menu)

TIFF Exports now have an export template that enables users to add standard text (e.g., name, date, etc.) to exported TIFF's. In addition, users can choose whether to include the legend and/or the XYZ axes (i.e., North Arrow) in TIFF Export. This is intended to improve non-georegistered exports to briefings and presentations that may not require georegistered products (e.g., PowerPoint).

Miscellaneous

• AVI movie creation from line now has choice of Above Ground Level (AGL) or Absolute (ABS) Altitude. Export...Movies Menu
• Added "Save Selection Area to ASCII". This will save the selection area polygon as a series of ASCII XYZ positions.

Bug Fixes/Optimizations

Applied Imagery has released Quick Terrain Modeler Version 6.1.0 and Quick Terrain Reader Version 6.1.0. Quick Terrain Modeler enhancements and bug fixes are as follows:

Quick Terrain Modeler x64: 64-Bit Support
In addition to the standard Quick Terrain Modeler, Applied Imagery has introduced Quick Terrain Modeler x64 (QTMx64). While functionally identical, the 64-bit version is written and optimized for 64-bit Windows architectures. Instead of 32-bit memory limitations (i.e., 4GB maximum loaded, normally 2GB maximum allocated to a process), QTMx64 can utilize the 8, 16, or 32GB of memory that are typically loaded on 64-bit workstations. This means that the maximum model size goes up dramatically. As a rule of thumb, QTMx64 can load 50 million points uncompressed or 100 million points compressed for every GB of memory allocated (E.g., a machine with 8GB of memory can load 350 million uncompressed or 700 million compressed points if 7GB is allocated to QTMx64).

Applied Imagery will support both 32-bit and 64-bit versions of Quick Terrain Modeler. They will be separate products. The 32-bit version will run in 32-bit emulation on 64-bit systems, but the 64-bit version will not run on 32-bit systems.

Grid Statistics:
Grid statistics is a powerful, fast, flexible, and visual tool that provides Quick Terrain Modeler users a way to statistically sort through their LiDAR or 3D data in almost any way imaginable. The user simply loads data, whether point cloud or gridded surface model, sets a grid size, selects a variable to investigate, a statistic to calculate, a way to display it, and (optionally) an action to perform on it. (Analysis Menu)

• Variables Supported: Z (Height), Intensity, Number of Points, Point Density, Alpha

• Statistics calculated for each grid cell: Minimum, Maximum, Mean, Range, Deviation, Slope, Aspect

• Statistical Display Options: Continuous Color Band (Blue to Red), Earth Tones (13 segments – no ramp), Color Wheel, User customizable

• Actions: Export, cut, or decimate by statistical bands. Save GeoTIFFs of either statistical values or color values. Save/load statistical profiles.

Statistical Model Comparison
Based on the grid statistics tool, the statistical model comparison tool allows a grid-based comparison of two models. The user loads two models, designates a baseline model, sets a grid size, and for each grid cell, Quick Terrain Modeler will calculate either RMSE or Difference in Z, Intensity, or Alpha. This is an excellent way to evaluate the impact of different gridding algorithms, surveying techniques, decimation/thinning methodologies, or before/after comparisons. (Analysis...Grid Statistics Menu)

Significant Line of Sight Upgrades
Added significant capability to Line of Sight analysis. New capabilities enable Basic, Interactivity, and Cumulative analysis for much more flexible and intuitive results.

HLZ Tool
This simplified tool will assist in identifying candidate locations for Helicopter Landing Zones (HLZ's) based on user specified parameters of slope and minimum radius. (Analysis...Add Vertex Colors to Model Menu)

Subtract Models
This tool allows users to subtract one entire model from another model on an elevation basis, leaving a "difference" model. (Edit Menu)

Markers

• Added marker "Quick Tags" that allow rapid tagging and counting of objects of interest. The user sets baseline parameters (color, marker name prefix, and count start point) and simply adds markers as normal. (Marker...Marker Options Menu)
• Added a marker keyboard shortcut. The user holds down "M", then left clicks to add markers.
• Added the ability to filter markers by attribute. (Markers Menu)
• New Markers add their names as an attribute upon creation.
• Added ability to save/load marker sensors. (Marker Sensor interface)

Grid Lines
Dramatically enhanced grid lines tool to support DoD needs for 3D MGRS map visualization. The user can now draw MGRS grid lines across 3D models, customize the display, and export the grid lines as sampled 3D shapefiles. (Analysis Menu)

Decimation/Thinning Enhancements

• Added spatial decimation capability that decimates selection areas. This is a "manual" decimation based on user defined or imported (from shapefile) areas. Accessed by "CTRL-Right Click" on a selection area.
• Statistical Decimation based on user defined statistical results (e.g., areas of low Z deviation) discovered in the Grid Statistics Tool. Accessed by right clicking on the display color scale in Grid Statistics.

Editing Enhancements

• Screen Select now allows users to select in "screen space" rather than down the Z axis. Accessed from the button bar.
• Context Menus for selection areas. Accessed by "CTRL-Right Click" on a selection area. This gives the user access to cutting, cropping, decimating, exporting, and area statistics.
• Sphere Select has been eliminated.
• "Flatten Area" now only applies to visible models.

Visualization Enhancements

• Voxel-based point auto sizing adds a new choice for point cloud visualization. Using this method makes "near" points large and "far" points small, thus lending an additional amount of realism to the display of points. Users can choose this method or the "traditional" auto sizing menu in the new Cloud Point Settings interface. (Display...Settings...Cloud Point Settings Menu)
• Added the ability to rotate in 2D mode.

LAS Support

• Added support for LAS Version 1.2. Users can now import/export XYZ-RGB (i.e. colorized) point clouds and surface models as LAS 1.2. (Import/Export Menus)
• Added the ability to import colorized point clouds from LAS 1.2 and export as LAS 1.1 by converting colors to grayscale "intensity" values. (Import/Export Menus)

Analysis Enhancements

• Enhanced Slope Analysis tools (Analysis...Add Vertex Colors to Model Menu)
• Area Stats now only lists models which intersect selection area.
• Added Z Mean and Z Standard Deviation to Area Statistics.

Model Compression/Memory Management

Added the ability to remove/add normals to point cloud (QTC) models on the fly. Removing normals significantly reduces model size, but can degrade the appearance of a point cloud. (Edit Menu)

Bug Fixes/Optimizations

• Added support for UNIX newline and Lockheed Martin "C3D" format to FXYZ Import widget.
• Fixed marker name sorting issue in dialog boxes when more than 10 markers were loaded.
• Fixed shadow map and terrain mask bugs.

Applied Imagery has released Quick Terrain Modeler Version 6.0.6 and Quick Terrain Reader Version 6.0.6. Quick Terrain Modeler enhancements and bug fixes are as follows:

• Google Earth synchronization.  This feature sends positional information in real time to Google Earth.  Users can now synchronize zooming, panning, rotation, and tilt with Google Earth.  This is found in the Control...Control Mode menu.  Simply check "Synchronize Google Earth"
• Import/Export markers to/from KML. (Marker Menu)
• Import/Export selection areas to/from KML. (Edit Menu)
• Import/Export mensuration lines to/from KML. (Analysis Menu)
• Export extents outline to KML.  This functions exports a single rectangle of area coverage to KML, even if multiple data files are loaded (Export menu)
• Drag and drop KML support.  This enables users to drag KML files from Windows menus and simply drop into the Quick Terrain Modeler environment.

LAS Support

• Added LAS "Quick Open" capability that opens LAS files without having to perform the "import" function.  When using LAS "Quick Open", LAS files will be opened as point clouds (.qtc) based on the most recent user-set import values in the LAS import options window.
• LAS Quick Open can be accessed by:
• "Open" file from the "File" menu or button bar.
• "Add" file from the "File" menu or the button bar.
• Windows "drag and drop" of a file into the Quick Terrain Modeler.
• DOS command line functionality using "qtmodeler.exe filename.las".  The command line functionality will enable passing LAS files to Quick Terrain Modeler from external applications.

Enhanced Slope Analysis
Version 6.0.6 significantly enhances the slope analysis and filtering tools.  New capabilities include:

• Customized slope banding.  Users can now set any number of slope bands and create customize palettes for coloration of the bands.
• Saving/loading of custom slope banding configuration and palette files.
• Slope area filtering is now integrated with slope banding in a single user interface.
• Added the ability to perform a continuous color coded slope model (from 0 to 90 degrees) over entire model.

  Model Compression/Memory Management

• Added the ability to compress QTT surface models.  QTT compression reduces QTT file size by approximately 20% on a model with no vertex colors.
• Added the ability to remove/add surface normals for QTT surface models.  Removing surface normals reduces QTT file size by approximately 45% on a model with no vertex colors.
• Added ability to select which model(s) to compress if multiple models are loaded.
• Added a Memory Management options interface that allows the user to set global preferences for compressing models and/or removing surface normals.  Both of these options can significantly impact the amount of memory used for a given model, thus impacting the maximum model size that can be loaded into memory. (File Menu)

Scatter Plot Profiles for Point Clouds

• Added the ability to visualize profiles of point clouds as "scatter plots" of points, rather than a single linear profile of the "surface" of the point cloud.  This feature is accessed from the normal height profile window.
• Users can visualize the scatter plot and/or the linear profile independently or together.
• Users can set the width of the scatter plot selection area.
  

North Arrow/3D Axes
Reworked the 3D Axes tool to make real world orientation more intuitive.  The axes now designate North, South, East, and West.  "Up" is also displayed.  ("Display" Menu...Options...Show Axes)

Bug Fixes/Optimizations

• Fixed issue of editing markers when more than 10 markers are loaded.
• Fixed issue of not exporting contours to shape file.
• Reversed order of Markers exported to shape files.
• Fixed point selection in Geodetic Models.
• Fixed issue with importing Intensity and Alpha to QTC.
• Fixed issue with losing contact with the Sentinel key (portable and floating licenses only).
• Increased the maximum number of vertices for selection polygons to 100,000.  (Note, this is the maximum number of vertices in selection the polygon, not the maximum number of vertices that can be selected in a QTT surface model.)
• Fixed issue with X position of contours being shifted (bug introduced after version 6.0.3).
• Fixed issue of area smoothing being applied to all loaded models.
• Fixed issue of failing to build QTT models from geodetic data if the user specifies a grid spacing less than one.
• Quick Terrain Modeler now assigns a file extension (.qtc or .qtt) as soon as a model is imported.
• Optimized ray tracing algorithms to enable more efficient point selection and rotation.
• Fixed issue with setting UTM Zone when loading Geodetic ESRI SHP Files and overlaying them on UTM Models.
• Fixed issue with profiling across models with differing UTM Zones.

Applied Imagery has released Quick Terrain Modeler Version 6.0.5 and Quick Terrain Reader Version 6.0.5. Quick Terrain Modeler enhancements and bug fixes are as follows:

Google Earth/KML Support :
Version 6.0.5 adds significant support for Google Earth.  This added support gives the Quick Terrain Modeler user a very fast and intuitive context capability.  At this time, these functions only support Vector and 2D products (e.g., model outlines, contours, 2D GeoTIFF's).  The specific upgrades are:

• Exporting model outlines and model information markers to Google Earth/KML:  With a simple button click, Quick Terrain Modeler will generate an outline of the loaded model, launch Google Earth, and export model information as a marker.  This function is accessed from the menu or the new "Export to Google Earth" button.
• KML Indexing Function:  This is identical to the Export model outline function, but it performs a batch process on an entire directory of QTT and QTC files at once.
• KML Options Setup:  Allows the user to define exactly what information should be exported to KML during the Export Model Outlines and KML Indexing functions
• Exporting Vector models to KML:  Vector models such as contour lines can be exported to KML.
• Exporting KML files along with 2D GeoTIFF Export:  When a user generates 2D GeoTIFF's, Quick Terrain Modeler will also generate an associated KML file to enable posting the image to Google Earth.

Coordinate Conversion/Go To Point:
The coordinate conversion tool is a new utility that provides the following set of functionality:

• Provides a simple way to convert a single point between five coordinate systems - UTM, Geodetic (decimal degrees), Geodetic (Degrees/minutes), Geodetic (degrees/minutes/seconds), and Military Grid Reference System (MGRS). 
• Allows the user to quickly zoom to the location specified in the interface or to pre-placed markers.
• Creates markers in specific locations.
• Converts existing marker positions between the five coordinate systems mentioned above.
• Determines elevation values for specific X-Y positions.
• This function is also accessed from the new "Go" button, right clicking on a point and typing "P", from the control menu, and from he marker menu.

Point to Point Viewing:
This new point to point viewing tool allows users to go to a specific marker, and direct the camera view to another marker.  It is a powerful tool for enhancing situational awareness and determining visibility between specific, known locations.  This can be found in the Control Menu, Point to Point Viewing.

Applied Imagery has released Quick Terrain Modeler Version 6.0.4 and Quick Terrain Reader Version 6.0.4. Quick Terrain Modeler enhancements and bug fixes are as follows:

Compressed Point Clouds:
Quick Terrain Modeler version 6.0.4 introduces compressed point clouds (.qtc). This significant enhancement will cut in half the amount of memory used by point clouds, essentially doubling the maximum point cloud size. There may be a slight tradeoff in precision, depending on the geographic extents of the model. Users can either import into the compressed format directly, or convert existing models to the compressed format.

Increased LAS Support:

• LAS Export: Quick Terrain Modeler now supports exporting to LAS version 1.1.
  
• LAS Pre-inspection: Filtering LAS files by classification upon import is now much more efficient.
  
• LAS Coordinate Assignment: Users can now assign a coordinate system/UTM Zone to LAS files that originally had no coordinate system.
  
• LAS Intensity Enhancement: Users can choose whether or not to scale intensity upon LAS import.

Marker Upgrades:

• Marker Information: Users can now import markers from a Comma Separated Variable (CSV) text file and attach an unlimited amount of information to each marker upon import. Users can then view this information in the context of point clouds and terrain models. With this enhancement, markers will not only call out a place in a terrain, but will deliver a significant amount of useful information to the user about objects in the terrain.
  
• Marker Import from Shapefile: Users can now import markers from a Point ZM shapefile.
  
• Real Time Coordinate Conversion: If a model is originally in UTM or geodetic coordinates, users can specify one of five coordinate systems (Geodetic in 3 formats, UTM, MGRS) to be displayed in the status bar as the cursor is moved through the model.

Mensuration/Profile Enhancements:

• Mensuration Line Enhancements: Users now have the option to display the length of the mensuration line as it is being placed. There are three options – 2D distance, 3D distance, and elevation change – that are available. In addition, the distance can be measured from the origin point or from the last vertex placed.
  
• Profile Zooming: Users can now zoom to a specific area in the terrain profile window by dragging a selection box. This will facilitate close inspection of sub areas of the terrain profile.
  
• " ALT": Press "ALT" key to suspend mouse controls while placing a mensuration line. This will permit users to reposition the display and facilitate placement of mensuration lines that were required to go beyond the extents of the current display.

Terrain Mask (USA Version Only):
Users can quickly simulate terrain visibility to an airborne sensor. Simply input graze angle and azimuth, and Quick Terrain Modeler will indicate which areas have visibility and which do not. There as also an "Obscuration Percentage" calculation that can be performed on the entire model or on a specific selection area.

Bug Fixes/Optimizations:

• All loaded markers are now saved with a tile set.
• Holding "CTRL" down while editing the visible model will now edit hidden models. This works on cut and crop only.
• Markers exported to shapefile now populate "Name" and "Altitude" attributes in the .dbf file.
• Fixed odd rendering issue for compressed DTED's.
• Fixed issue saving multiple files from multiple classification in LAS batch import mode.
• Fixed issue with non-visible marker disappearing during vector LOS analysis.

Applied Imagery has released Quick Terrain Modeler VErsion 6.0.3 and Quick Terrain Reader Version 6.0.3. Quick Terrain Modeler enhancements and bug fixes are as follows:

Marker Upgrades:

• Marker ID: In many cases, Quick Terrain Modeler users may have identical marker names, so Applied Imagery has added the ability to see a unique Marker ID associated with each marker. This will allow users to distinguish between individual markers during the edit, show/hide, and remove marker operations. Marker ID's will now be visible in the Edit Marker, Remove Marker, Show/Hide Marker, and (optionally) as part of the marker name in the main display window.
  
• Show/Hide Markers: Users can now select a subset of markers to be visible without removing any markers.
  
• Importing Markers: During Marker ASCII import, users can now select any column as the marker name. In addition, the text preview pane has been expanded to support ASCII file formats that have large amounts of metadata (header rows) at the top of the page.
  
• Autoscale Markers: Users can choose to autoscale the marker size. If this option is chosen, markers will get bigger when zoomed out and smaller when zoomed in, thus eliminating "giant" markers when zoomed in and "microscopic" markers when zoomed out.
  
• Marker "Point and Click": Version 6.0.3 enhances the ability to "point and click" on markers. In order to pull up the Edit Marker window for a specific marker, click the marker button, then right click on the desired marker. In order to move a marker, click the marker button, left click on a marker, and drag it to a new location.
  

Editing:
Cut and Crop now only apply to the visible model. In past versions, cutting and cropping would apply to all models, whether they were visible or not. To apply an editing function to a single model, simply show that model, hide all others (show/hide model window), perform the edit function, and continue with analysis.

Shapefile Overlay:
When importing 2D shapefiles, Quick Terrain Modeler assigns elevation values to the vertices of 2D shapefile polylines and polygons upon import. The result is that, in some cases, the vector lines will "pierce" the surface and become difficult to visualize. Version 6.0.3 adds the ability to permanently raise or lower imported 2D shapefiles. This will give users the ability to see shapefiles and GIS layers much better, particularly in highly varied terrain.

Density Calculation:
Point density is a basic statistic that users need to know. In past versions, users could get the average point spacing (i.e., "posting") of a point cloud by looking at the "Scale" number in the Model Statistics and Area Statistics windows. Version 6.0.3 adds a "Density" calculation that gives the same result (point density), but describes it differently. Density is measured in points per square unit. For example, a Density value of 1.4 means that, on average, there are 1.4 points in a square meter (assuming the model is measured in meters. This calculation is done for an entire model in the "Model Statistics" window and for a specific area in the "Area Statistics" window.

"ALT" Hot Key:
When selecting specific areas with the selection area or selection polygon tools, users may need to zoom out, pan, tilt, or rotate to be able to see areas just outside the current view. Users can now hold down the "ALT" key to manipulate models while in the process of creating a selection area. Simply release the "ALT" key and resume placing vertices in the selection polygon or stretching the selection rectangle. This improvement eliminates the need to close a partial polygon, zoom out, and start again.

New DEM Format Support:
• Support for USGS DEM format: Users can now import USGS DEMs. Please note to use the "Import Model" rather than the "Open Model" function.
• Support for InterMap DEM formats: Version 6.0.3 will open InterMap's 16-bit and 32-bit GeoTIFF DEM formats. In addition, users will have the choice to convert to UTM upon opening the models.

Bug Fixes/Optimizations:

• Fixed intensity display on very old QTT and QTC models.
• Added filter to ignore errant data during Point ZM import.
• Changed LAS import function to ignore unit conversion upon importing to Cartesian coordinates.
• Fixed calculation of "Scale" value in "Area Statistics" window.
• Fixed issues merging DEM's with highly varied grid spacing.
• Enabled rotation/tilt of model after selection polygon is created.
• Created separate .ini files for all import interfaces. This will ensure that QT remembers all user settings uniquely for each type of import.
• Transposed X and Y values in "Edit Marker" window (Cartesian only).
• Added .txt and .xyzi as standard extensions for ASCII XYZ import.
• Added .txt as the standard ASCII Z-Grid import and export file extensions.
• Sensor model (Line of Sight) terminology has been modified to better reflect the perspective (i.e., from the sensor) from which the angles and distances are measured.

Windows Vista: With any new operating system, there are potential driver compatibility issues (e.g., graphics driver, etc.). While Vista/OpenGL driver compatibility issues have been resolved, there have also been issues with Vista and the Sentinel driver. With the release of Version 6.0.2, Applied Imagery has included the new Sentinel Driver, 7.4.0, which is Vista compliant. At this time, Applied Imagery does not certify the functionality of Quick Terrain Modeler on Vista OS.

2008/2009 Update: There are currently no known compatibility issues with Windows Vista and Vista X64. All the above issues are resolved.

If you are still experiencing compatibility problems with Vista and any other driver related to Applied Imagery's software, please contact support@appliedimagery.com.

Applied Imagery has released a new version of Quick Terrain Modeler and Quick Terrain Reader. Quick Terrain Modeler enhancements and bug fixes are as follows:

Line of Sight Enhancements (US Version Only):

• Vector Line of Sight: Users can determine whether Line Of Sight (LOS) exists between a traveler moving down a path and observers (markers) in the terrain. Results are displayed in real time as red or green vectors and will show both air and ground distances to the target.
• Sensor Model Line of Sight: Allows users to set sensor parameters (e.g., surveillance camera, microwave communication antenna, airborne sensor, etc.) to determine coverage areas in a terrain.
• Ability to Set Markers/Observers with a height Above Ground Level (AGL): Users can import markers/observers into a terrain and specify relative rather than absolute heights.
• Flexible Line of Sight Analysis Export Choices: Many more choices to adapt to downstream software applications that have specific import requirements.

Export Entire Point Clouds to PointZM Shapefile: Adds ability to export entire point clouds to PointZM shapefile format, thus enabling true 3D vector import of ungridded data into other applications (e.g., ESRI)

Expanded Search Radius and Speed for Quality Assurance and Ground Truthing Tools: Point Query Utility now will "look" much farther from ground truth points to find points in a QTC point cloud. Thus, in areas of sparse data, QT will be more effective in polling the point clouds, returning model elevation values, and creating QA reports that comply with FEMA specifications.

Spherical Selection/Editing Tool: Adds the ability to select groups of points with a resizable sphere selection tool.

Point Cloud Color Editing: Users can recolor points in a QTC point cloud. Requires that the point cloud already have RGB values for each point.

Flood Water Level Appears in Terrain Profiles: Allows users to see flood levels relative to specific profiles.

Remove Individual Anchors: Added the ability to remove individual anchor pairs in scan alignment module.

Georegistration Enhancement: Added the ability to use model origins as the basis for georegistration.

UTM Zone Handling: Now handles UTM Zone boundaries much better. QT will now attempt to avoid leaving the user-specified UTM zone unless multiple models in multiple zones are loaded.

Bug Fixes:

• Fixed bug that caused crash when looking at non 1m gridded data on edge.
• Fixed automatic scan alignment (ILRIS) bugs.
• Decoupled Az/El and time of day setting on lighting GUI.
• No longer resets lighting on model load.
• Fixed roundoff error in QTC draw routine (dropping points along a linear edge).
• Fixed conversion of geodetic QTC to QTT bug.
• Fixed issue on 90 degree azimuth shadow mapping results.
• Fixed bug interpreting certain GeoKey values, particularly noted on LAS import.

Quick Terrain Reader Version 6.0.2 Upgrades: Eliminated maximum model number limitation. Users can now view any number of models simultaneously (subject to normal memory constraints).

Applied Imagery has released a new version the QT Modeler and renamed it Quick Terrain Modeler. The new version adds the following features:

Point Query Utility (Quality Assurance Tools): The new point query utility makes ground truth reporting easy. The revised tool imports points from an ASCII file, compares them to the surface (or TIN created from a point cloud) and delivers a customized ASCII report to the user. The customized report can contain the original point ID, the original XYZ of the ground truth points, as well as the Z values of the model, the delta Z at each point, and/or classification and other values that were in the original data file. Users can also calculate RMSE for the entire data set.

Georegistration: Version 6 adds a powerful georegistration tool that attaches pre-saved georeference points to specific points/vertices of a model. This interactive process graphically places the georeference points in 3D, then computes X, Y, Z, pitch, roll, and heading offsets. If the RMS error is within tolerances, all model points will be translated to the new coordinate system. This tool will work on multiple models simultaneously.

ASCII Vector Import: This new tool, similar to existing tools to import vectors from Shapefiles, extends vector support to ASCII vectors. Users can import vectors in the format of "X, Y, Z, VectorID", such as the Landmark ASCII fault file format and other vector formats that are stored in this manner.

Find Highest Point: For applications such as vertical object detection, Quick Terrain Modeler can now find the highest point in a given selection area. Simply draw a selection polygon around an area, and choose "Find Highest Point In Area" from the analysis menu. Quick Terrain Modeler will find the highest point, open the point interrogation window, and allow users to create a marker at that precise point. Markers can be saved as markers (.mrk format) or exported to ASCII and/or shape files.

Rescale Heights Button: Users can now access the "Set Height Scale" functionality by clicking a button in the tool bar. Since many users frequently access height exaggeration (particularly in a Quality Assurance/Quality Control environment), the new button will make mundane tasks easier and quicker. Furthermore, the height scale, if it is set to anything other than "1", will appear in the updated status bar at the bottom of the screen.

Reconfigured Dynamic Status Bar: Quick Terrain Modeler now has a dynamic status bar at the bottom of the screen. New information is now available such as height exaggeration and model name. If multiple models are loaded, the status bar will display the model name of the model directly under the cursor. This makes navigating and zooming in to multiple tiles/models much easier and more intuitive.

Match Model Altitudes: The altitude matching tool uses an improved matching algorithm, has added choices in sampling level for faster calculation, and offers a choice in setting the reference model. In addition, the match altitude tool can now match point clouds (QTC's).

Faster ASCII Importing: Version 6 ASCII importing is much faster.

Support for DTED DTC format: Version 6 completes support for the DTED format known as DTC. DTC's are standard DTED models with sub-integer resolution in elevation. Quick Terrain Modeler automatically recognizes this format and can convert to UTM upon loading.

Point Interrogation – Create Markers: Quick Terrain Modeler's point interrogation tool lets users query any point/vertex in a model, then a open a window which displays the X, Y, Z, and color values of that point. Version 6 adds the ability to create a marker at that point

Binary Import: The binary import window now has an ASCII header preview window to allow users to inspect the data in the binary header (assuming this data is ASCII) prior to import. Version 6 also adds support for binary color (RGB), and Intensity/RGB scaling tools.

Binary Export Choices: Users can now choose between Binary XYZI and Binary XYZRGB upon export.

Quick Terrain Modeler Scan Alignment Upgrades:

Scanner Origin Tracking: Create and export the ILRIS origin point (0,0,0) for use later during the georegistration process. A new Quick Terrain Modeler display option setting will highlight the origin points when the scans are exported to QTC Point Clouds.

Georegistration: After performing scan alignment and exporting to QTC point clouds, users can import georeference points from an ASCII File and manually correlate them to points in the scans. Quick Terrain Modeler will transform the point clouds from project/plant coordinates to real world coordinates.

Stationary Scan Selection: Select a scan by name to hold stationary during the export process. Therefore, all aligned scans will be transformed to the scan coordinates of the stationary scan.

Merge Sessions: This feature links two or more sets of pre-aligned scans and only requires the user to manually align the overlap of these sessions. Users can align individual scans (e.g., automatic scan alignment from the ILRIS 36D Pan/Tilt Base), save as a session, then merge and import multiple sessions.

Auto Alignment for Multiple Regions of Interest: Users can now auto-align scans from multiple regions of interest, as long as they overlap and are contained in the same IXF file.

Resizable Preview Windows: Users can make preview windows much larger for easier and more precise anchor placement.

Quick Terrain Reader Upgrades:

More Models: Quick Terrain Reader Version 6 opens 2 models at the same time (Version 5.1.5 limited the total number of models to 1). This upgrade would enable the distribution of a point cloud and a surface model of the same region.

More Markers: Quick Terrain Reader Version 6 Creates and/or imports an unlimited number of markers (Version 5.1.5 limited the total number of markers to 4). Users can now create models with dozens of markers (points of interest, targets, etc.) and share them with downstream users for free.

Applied Imagery has released a new version the QT Modeler. The new version:

-- Adds a "Convert Models" function in the Edit menu that converts models (e.g., QTT from QTC) without having to reload and reimport data. This function also allows users to convert only a portion of the loaded model by cropping to a polygon selection.

- Exports QTC point clouds to ESRI point shape files.

- Exports markers to ESRI point shape files and to ASCII text files.

- Adds a button for Show/Hide Models. This makes isolating and comparing multiple models easier.

- Crops a data set to the X-Y extents of an external shape file upon import. This is a way to identify specific areas in GIS, then import only the necessary points from a large data set.

- Adds a feature to limit the distance on Line of Sight (e.g., perform line of sight out to 200 meters) as well as perform Line of Sight on multiple markers at once. (USA Version Only)

- Supports enhanced dynamic range DTEDs. These DTEDs are based on the MIL-PRF-89020A standard and support sub-integer level of detail for elevation values. Users will simply load these DTED's just as DTED's are normally loaded - no manual process is necessary.

- Adds a Sentinel restart button on all Floating and Portable licenses. This enables users to restart the Sentinel drivers in the event QT Modeler loses contact with the Sentinel key.

- Added GeoTIFF export option to comply with GDAL standard of the "No Data" value in the exported GeoTIFF DEM header.

- Various bug fixes and optimizations.
