Note: Upgrading to Quick Terrain Modeler Version 6.1.2 does not require a new key. Simply download the appropriate version below, install, and run. If your new version asks for a new key, you have probably downloaded the wrong version. If you are unsure whether to download 64-bit or 32-bit, you most likely are running a 32-bit operating system and 32-bit Quick Terrain Modeler.

Quick Terrain Modeler Version 6.1.2:  What’s New?

Release Date:  March, 2009

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:

1.       Calculate AGL heights of every point either by comparing to a bare earth model (if available) or by quickly estimating a ground surface.

2.       Once AGL Values are calculated, apply a color scheme based on AGL heights, rather than absolute heights.

3.       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.

4.       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.

5.       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:

1.       Much more comprehensive “Marker Options” menu (Markers Menu) that enables the setting of most marker display options from a single interface.

2.       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.

3.       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)

1.       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.

2.       Added legend support for Grid Stat calculation displays.  The legend will now display the statistic calculated, the color range, and the range values.

3.       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.

4.       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., Power Point).

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.
