Distance matrix seems only > use measuring between point object. probably the fastest way to obtain it is with postgis (a lot can be done from within of the postgis manager plugin) Example SELECT ST_Distance(ST_Transform(a.the_geom,your_srid), ST_Transform(b.the_geom,your_srid)) AS distance_between_geometries FROM pol1 a, pol1 b WHERE a."attribute_name" = 'attribute_value' AND b."attribute_name" = 'attribute_value' see http://postgis.org/documentation/manual-1.5/ST_Distance.html cheers -- Giovanni -- _______________________________________________ Qgis-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/qgis-user
