I think this should work (but you should double check): if aspect <= 90, then azimuth = 90 - aspect else: azimuth = 450 - aspect i.e. r.mapcalc "azimuth_aspect = if(aspect <= 90, (90 - aspect), (450 - aspect))" Moritz _______________________________________________ grass-user mailing list [hidden email] http://lists.osgeo.org/mailman/listinfo/grass-user
