"as it is", http://marcocorvi.altervista.org/tbe.tgz it is good that thierry and wolfgang can work on the integration of therion with "geography". it is something i do not know much about. marco

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?

[Therion] therion and DEMs
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)... Thierry

Hi Thierry, I'm also using Grass for preparing my images and the DEM. So it would be nice to share experience.

[Therion] therion by examples
I've put in the *FRENCH* section of wiki (I'm planning a translation, one day !!) about integration of Therion datas in OpenSource GIS, in this case, GRASS, and DEM use... If Wolfgang want some help... I could help Marco, but don't have many time !!
