SlashGeo pointed me to LandSerf, an interesting bit of free GIS software (not open source) for viewing and analysis of DEMs, TINs, and other files in 3D. It uses OpenGL for the 3D graphics, and has a variety of features for lighting/shading, blending of multiple images, and supports a bunch of import and export file formats. It runs on PCs, Macs, and Linux/Unix as long as you have the Java Runtime Environment. I didn’t explore too far, but it appears that it also has some scripting/API support. (Image by LandSerf)
I introduced this ruggedized field tablet PC by Trimble here back in March, but there wasn’t any pricing information available at that time. To refresh, it has a military grade ruggedized design to keep out dirt and water, 32GB solid state drive (no moving parts), built in GPS, Wi-Fi, bluetooth 2.0, 2 integrated digital cameras with geotagging functionality (why 2?), Windows Vista Business, and a 7″ sunlight readable screen all in a 2.6-lb package. Read on for the $$.
