Hi, The problem was that I had to run the g.region first so that I would set up my raster resolution!!!
Then I imported my DSM, ran first r.slope.aspect to calculate slope and aspect and then I ran the r.sun algorithm and I had my first correct results!! Thank you very much everybody for your valuable help!! -- View this message in context: http://osgeo-org.1560.n6.nabble.com/Importing-ASCII-file-tp4984276p4997732.html Sent from the Grass - Users mailing list archive at Nabble.com. _______________________________________________ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
