Did you try the SQLite driver? Just create a new mapset, define the connection with "db.connect" (see manual for copy-paste command) and "g.copy" the map from the DBF mapset into the sqlite mapset. Then the joys of SQL are available. Markus _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
