Hello. I am trying to add some raster maps. I thought I could do this in r.mapcalc, but "new_map= old_1 + old_2" seems to produce a map where the maps overlap and ignoring areas where only on of the maps have values. I would like to do something similar to "v.overlay operator=or".
Anyone who knows how to do this? Martin Ytre-Eide_______________________________________________ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
