What file formats does TerraVision support?

This includes: USGS 7.5-minute DEMs, USGS DOQs, DTED Level 0, TIFF, GeoTIFF, JFIF/JPEG, GIF, PPM, PGM, and raw binary grids. In addition, the 8.1 release of the 3D Extension for ESRI’s ArcInfo product provides export support for GeoVRML. • How can I add support for another file format? The tsmApi tools are Open Source so you are welcome to add support for new file formats. The code for reading different image and elevation formats was written to allow new format support to be easily plugged into the existing architecture. Download the tsmApi source code and take a look in the tsm/tsmCreate.c file for details. • Why does TerraVision support GeoVRML? GeoVRML is an e
