With g.region. With the "rast=" argument you can set it to match a raster - both the spatial extent and the resolution will be set to match.
r.mapcalc uses the regional settings for its calculations, so if the region is set at a low resolution, or the spatial extent is very small, it could explain why you're getting such a small raster as a result. -- View this message in context: http://osgeo-org.1803224.n2.nabble.com/r-mapcalculator-r-mapcalc-not-producing-raster-tp6041018p6041173.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
