Hey PostGIS Friends, here's a problem that's stumping me, hoping you can help:
I have a bunch of polygons, many of which overlap with each other. I would like to trim down the set of polygons to only those that do not overlap. I'm not particular about which I delete, so long as they overlap by a certain %. Any thoughts on how to do this? I was trying for a self join but can't figure out how to not to delete all polygons that overlap. Cheers, dylan _______________________________________________ postgis-users mailing list [email protected] http://postgis.refractions.net/mailman/listinfo/postgis-users
