Ok, now it's clear. That's a good point... maybe one could write an algorithm similar to r.grow or r.lake: add pixels starting from a point until a pixel with the same category of the seed is found. A good exercise :-) _______________________________________________ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
