Applied Imagery Quick Terrain Modeler 8.4.3.1.1 (82946)

Data Explorer – More Versatile Than Ever!
QTM’s Data Explorer is now the best option for online data discovery and retrieval. The evolution of Data Explorer began as a STAC-based solution, but now also interfaces seamlessly with EPT-based point cloud repositories, including USGS 3DEP and NGA’s GRID. Users can simply point to a repository from the QTM pulldown menu or from custom repository locations, all while using a friendly, map-based environment. Some distinctions between types of repositories:
- STAC: QTM’s existing implementation enables exploration of enormous repositories of a wide variety of data types (point clouds, DSM/DTM’s, imagery, etc.). Draw your Area of Interest (AOI) on the map, see what is available, and download as desired.
- EPT: Similar to STAC but focused exclusively on point cloud data. Users will discover entire collections, from which their AOI carves out a custom, single point cloud (see image below). If desired, this point cloud can be modified (e.g., downsampled, filtered) via QTM’s Point Cloud Toolkit prior to download, potentially saving valuable download time and bandwidth.
- WMS (Web Mapping Server): While technically unrelated to Data Explorer, don’t forget that newly downloaded 3D data can be supplemented with fresh 2D imagery and maps from a variety of public (e.g., Google Maps) and private (e.g., Maxar G-EGD/Digital Globe) sources, enabling rapid creation of integrated 3D scenes.


LAS/LAZ Support – Unlimited Nonstandard Attributes
QTM v8.4.3 adds support for custom, nonstandard LAS attributes. This means that QTM-created point attributes such as Above Ground Level (AGL) height can be retained upon export and reused and/or shared with other users. Users have full control of which attributes get included in the export files.


Export to ATAK – Support for COT2525 Markers
QTM now exports markers to ATAK as CoT 2525 icons. This means that QTM markers no longer appear as a pushpin. The default icon is the white Spotmap icon, but QTM will include a small library of other icons to choose from. All of this gets exported as part of the standard ATAK data package export.


Combine Routes (Right Click Routes Folder)
QTM v8.4.3 adds the ability to merge multiple routes together. This will make combined route time analysis possible. For example, an Infil route could be merged with an Exfil route to analyze total travel time. Users can choose to export the combined route or to only use the combination for time analysis.


Marker Rename/Resequence (Marker Manager or Right Click Marker subfolder)
QTM v8.4.3 adds a very flexible and fast tool to rename and resequence markers. This can be very helpful in GRG creation, or any task that requires many markers with a numeric or alphabetical sequence.
