The drawing is indeed a model of a building. My purpose is to make a calculation of solar irradiance and calculate the effect of shadow on an installation of PV-panels. So first step is to create a DEM of the buildings (and trees) of interest.
I managed to import the Google Sketchup collada file via Meshup (dxf). Small issue is that the model seems to be in inches now in Grass, but i will look into this. Biggest issue i have is to get from the 3d-vector (faces) to isolines. I'm happy to contribute to the wiki if i find a way to get this done! -- View this message in context: http://osgeo-org.1803224.n2.nabble.com/From-3d-vector-to-DEM-tp5967576p5974339.html Sent from the Grass - Users mailing list archive at Nabble.com. _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
