Hi all, Anybody know a well documented and efficient method to remove overlaps in a polygon table using PostGIS?
I can think of two cases: a) I may want to do it on a single table containing overlaps. b) I may want to do it because I want to update a clean (non-overlapping) table with a new one of smaller extent. In both cases I would like to be able to define/use a best polygon selection strategy (based on a year attribute for example). A small detail: I want to do this on a table containing 26 000 000 polygons... Thanks for any input, Pierre _______________________________________________ postgis-users mailing list postgis-users@postgis.refractions.net http://postgis.refractions.net/mailman/listinfo/postgis-users
