3DEM 20.7

3DEM is an application that creates three-dimensional terrain scenes and flyby animations from various freely available data sources. These data sources include USGS Digital Elevation Model (ASCII DEM) files, USGS Spatial Data Transfer Standard (SDTS DEM) files, NASA Shuttle Radar Topography Mission (SRTM) files, LIDAR Point Cloud (LAS) files, USGS Global 30 Arc Second Elevation Data Set (GTOPO30 DEM) files, NOAA Global Land One-km Base Elevation (GLOBE DEM) files, NASA Mars Orbiter Laser Altimeter (MOLA) files, and any topographic data file organized by rows and columns of elevation.

- NASA - Shuttle Radar Topography Mission (SRTM) files
- LIDAR - Point Cloud (LAS) files
- USGS - Global 30 Arc Second Elevation Data Set (GTOPO30 DEM) files
- NOAA - Global Land One-km Base Elevation (GLOBE DEM) files
- NASA - Mars Orbiter Laser Altimeter (MOLA) files
- Any - topographic data file organized by rows and columns of elevation data
- XYZ - scattered point topographic data files
