Use something like this: v.db.addcolumn map=sites column="sites_cost int" (or double precision depending on how your cost is defined) v.distance from=sites to=costs from_type=centroid upload=to_attr column=sites_cost to_column=cost_column_in_points_map Moritz _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
