FWIW, it works for me; sort of. However: I note that it generates a distinct category for each cell which is null in all inputs. If the number of cells is large and the inputs contain many null cells, this could result in memory exhaustion and/or extreme computation times. I believe that the problem is due to an incomplete conversion from the 4.x G_get_map_row() function (which maps null to zero) to the 7.0 Rast_get_c_row() function (which leaves null as-is, i.e. -2^31). I.e. it now reads nulls as nulls (instead of zeros) but doesn't actually make any attempt to deal with the nulls which it gets. -- Glynn Clements <[email protected]> _______________________________________________ grass-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-dev
