If that's the real query you're needlessly requesting computation of the intersection space, which is having robustness issues. Maybe you want to use ST_Intersects(A, B), which doesn't have the robustness issue and is likely also faster. --strk; () Free GIS & Flash consultant/developer /\ http://strk.keybit.net/services.html _______________________________________________ postgis-users mailing list postgis-users@postgis.refractions.net http://postgis.refractions.net/mailman/listinfo/postgis-users
