Hello Thank you both for those inputs.
I have finally decided to use a difference because in a second step the non-covered geometry interests me too. About my area solution, yes it worked because I am sure that my table contains only BBox and those are touching but never overlapping others. Thank you again. Nicolas. _______________________________________________ postgis-users mailing list [email protected] http://postgis.refractions.net/mailman/listinfo/postgis-users
