The above (being unable to include Egypt when island is added) still depends on the tolerance value, right ? There's probably a spatial configuration between those 2 polygons that triggers an excessive snapping with high tolerances. Keep your tolerances low! Or, insert the island in the topology as the last thing, and see where the error ends up being (the whole point of building the topology incrementally rather than in a single step is to be able to deal with each case separately, and spot what's special about it) --strk; _______________________________________________ postgis-users mailing list postgis-users@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/postgis-users
