#5434: Add preserve_topology option to GEOSGeometry.simplify -----------------------+---------------------------------------------------- Reporter: rcoup | Owner: nobody Status: new | Component: GIS Version: SVN | Keywords: sprint Stage: Unreviewed | Has_patch: 1 -----------------------+---------------------------------------------------- By default, simplify() does not preserve topology - e.g. polygons can be split, collapse to lines or disappear holes can be created or disappear, and lines can cross. The attached patch adds a `preserve_topology` parameter. If `True` (default is `False`), the result will have the same dimension and number of components as the input. This is significantly slower.
