Ok, I'm wondering if using the notice message could be used in conjunction with linear referencing functions to add the missing point to the failing linestring(s): 1- identify failing linestrings (or offending coordinates, then finding the closest linestring to this point) 2- complete these linestrings with new points built from coordinates 3- relaunch the union procedure. Though I've never done this. Nicolas _______________________________________________ postgis-users mailing list [email protected] http://postgis.refractions.net/mailman/listinfo/postgis-users
