Powerful 3D visualization

Quick Terrain Modeler is the world's premier 3D point cloud and terrain visualization software package. Designed for use with LiDAR, but flexible enough to accommodate other 3D data sources, Quick Terrain Modeler provides an easy to use software experience that allows users to work with significantly more data, render larger models, analyze data faster, and export a variety of products. These benefits enable very powerful, yet simple and intuitive, terrain exploitation.

Fast and easy

With each successive release, Applied Imagery makes using Quick Terrain Modeler easier and faster. Our latest release, v8.0.4, includes many new tools QTM users have been requesting. These tools will enable the exploitation of bigger data sets, accelerate frequently used tasks, and make our users' lives easier.  Feel free to give it a try!


Version 8.0.4 Is Now Available!

January 6, 2015:  Quick Terrain Modeler Version 8.0.4 is now Available!  With v8.0.4, Applied Imagery continues to enhance our users’ workflows by accelerating common tasks, adding analytical tools, and, in general, making life easier:
Digital Elevation Models (DEM’s, DSM’, etc.) will now consume 40% - 60% less memory, thus enabling analysis of even bigger areas.

We have achieved significant speed upgrades by implementing improved multithreading and other techniques.  You will see these improvements in in commonly used tasks such as point cloud loading, Helicopter Landing Zone (HLZ) calculation, Line of Sight (LOS) calculation, image (texture) import, cut/crop, area statistics calculation, and many other functions.

  • Interactive Vectors:  All vectors will now be interactive in the 3D scene.  This means selecting, dragging, rotating entire vectors and/or individual nodes. 
  • Flight Surfaces & Bounding Boxes:  Entirely new tools that will enable users to define rectangles and visualize “flight surfaces” for a more comprehensive HLZ/LZ flight planning experience, as well as easy identification of obstructions to aircraft approach.
  • Route Planning Revamped:  Route planning will be much simpler and will no longer display markers at every turn point.  Now you will simply create a measurement line, edit the line, then convert to a “QT Route” – no confusion about what markers belong to what route.
  • Distances in meters and heights in feet – at the same time!:  By user demand, measurements can now be made in separate units for vertical and horizontal objects.  For example, a route could be measured in the 3D scene and the distance would display in meters, but vertical change would display in feet.
Please read our "What's New in Quick Terrain Modeler" information sheet or Watch the What's New v8.0.4 Video for more details.  As always, we appreciate all of your feedback and suggestions.  Please keep the great ideas coming!

Point Cloud Cranes: High resolution point clouds deliver unparalleled understanding of potential vertical obstructions.

High Resolution Point Cloud: Easily visualize and analyze large, dense point clouds.

Colorized Point Cloud: Overlay GeoTIFF, MrSID, ECW, NITF, and other imagery. Sample colors into points/DEM's, export LAS 1.2 with RGB values.

Draping Imagery: Draping 2D imagery over a 3D DEM enhances realism and understanding of terrain.

Google Earth: Seamlessly integrate the view and export products to Google Earth.

USGS DEM: Not limited to LiDAR - Quick Terrain Modeler works with DTED's, USGS DEM's (shown), SAR, Sonar, and many other sources of 3D data.

Points-Dems: Display point clouds and DEM's simultaneously.

Grid Stats: Effortlessly perform QA/QC and other complex statistical analyses. (Shown: Statistical analysis of LiDAR point density - orange areas show flight line overlap).

Line of Sight: Line of Sight analysis quickly determines visibility within a terrain.
