[Therion] therion and DEMs

[thierrygonon]

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)...
