If the maps are integer-valued, use r.reclass to map the undesired categories to null. If the maps have floating-point values, use r.mapcalc instead. While the r.mapcalc approach will work for integer values, it copies the map data, while r.reclass only need to store the reclass rules. -- Glynn Clements <[EMAIL PROTECTED]> _______________________________________________ grassuser mailing list [email protected] http://grass.itc.it/mailman/listinfo/grassuser
