Description
Splits parts of multipart polygons into separate polygons. The 'simple' method separates all parts of a multipart polygon no matter if it is an island (outer ring) or a lake (inner ring). The 'fast' method takes respect of lakes but might fail on complex nestings (islands in lakes in islands in lakes...). Default is the 'precise' method, which also takes respect of complex nestings but processing might take significantly more time on large and complex polygons.
