Hallo, I've got a point file and populated (v.what.rast) it with values from a flow direction raster (flow direction from r.watershed).
I want to use these values to rotate the symbol in ps.map but therefore I've to recalulcate the values in the direction-column of the point file (x*45+90 or so). How can that be done? I thought about v.reclass but don't really know how?! Another option would be to access the sqlite database and perform the calculation there (I am working in a python script) like: database = sqlite3.connect(os.path.join(gisdbase, location, mapset, 'sqlite.db')) db = database.cursor() db.execute .... but what is the correct command for calculation within a database?? Probably it is easier than I think... :) /j -- NEU: FreePhone - kostenlos mobil telefonieren und surfen!
