Hi Wolfgang,
I'm using the Nasa SRTM DEMs, with the 90m precision. I've also used the functions that allows the transformation of vector level lines in DEMs, so that I can visualize them through nviz (include in GRASS) or Paraview (own installation). To import therion datas, I export them from therion in SQL format, but it only delivers the axis points... I still didn't try the new feature (ESRI Shapefile export)...

for therion -> grass I'v used the dxf output which I then converted externally to shp which I've imported to grass, but I also have to test the new shp output of therion (is on my to do list) but I thought more on the link from grass to therion. Transformation of SRTM data to a rectangular grid and exporting to ascii file and finally importing that into therion. The new 3D viewer (loch) is much nicer than nviz in grass ;-) I also thought on how to get satellite images / airophotos and how to use them as overlays. For some European countries as well as for the US and Canada there are some nice server where you can download some data, but mostly you have to stitch many tiles together so that you finally have one big overlay for your region of interest. more ideas?
