Hi, Attached is a python script and 2 AWT-files with a polygon and multipolygon.
The python script reproduces the following problem : p1.difference(p2) : shapely.geos.TopologicalError: This operation produced a null geometry. Reason: unknown I cannot see what causes this TopologicalError. A small change in our geometry makes this operation working fine again. Both polygons look perfectly correct. Can somebody with a more in-depth expertise in Shapely and GEOS take a look at this please? many thanks, Emmanuel
