Valid Terrain Formats
You can use an STK imagery or terrain converter to convert raw terrain and imagery to .pdtt and .pdttx file formats. You can use these files for 3D visualization in STK.
The following table contains the keywords and descriptions of the terrain types that can be imported using the stand-alone terrain converters. For more information on the terrain formats, see Terrain Sources.
