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 and KML Support

Version 6.0.6 adds additional  support for Google Earth and KML.  These upgrades enhance the KML capabilities originally introduced in Version 6.0.5.  The specific upgrades are:

• 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.
• Fixed potential problem importing LAS over network.

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.

Vector Line Width
Added the ability to set the thickness of vector lines.  Found in the Display...Settings...Set Vector Line Size menu.

Bug Fixes and Optimizations

• Added the ability to select different colors for slope analysis.
• Enhanced clarification on LAS import when coordinate system is either unknown or absent.
• Modified the clipping plane tool to clip directly on elevation, rather than the proxy value of height coloration.
• Fixed issue of creating large rectangles in areas of no data.
• Fixed issue importing large (over 1024 characters per line) CSV files as markers.
• Fixed issue of checkmarks not showing up in the File...Options menu.
• Fixed issue importing ASCII data in geodetic coordinates to QTC point clouds.
• Fixed bug related to large numbers of small files.
• Fixed bug related to importing shape files as vector into UTM models.

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.

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.
