Dear All,is there a function to easily subtract a polygon from a polygon. Both are rectangles.
The scenario: Two overlapping polygons identified by ST_INTERSECTS. Creating a third one from the overlapping area via ST_INTERSECTION. Subtract the overlap from the two initial polygons. Which function? Any suggestions?
