- minimum_clearance(geometry, **kwargs)#
Computes the Minimum Clearance distance.
‘minimum_clearance’ requires at least GEOS 3.6.0.
A geometry’s “minimum clearance” is the smallest distance by which a vertex of the geometry could be moved to produce an invalid geometry.
If no minimum clearance exists for a geometry (for example, a single point, or an empty geometry), infinity is returned.
- geometryGeometry or array_like
See NumPy ufunc docs for other keyword arguments.
>>> from shapely import Polygon >>> polygon = Polygon([(0, 0), (0, 10), (5, 6), (10, 10), (10, 0), (5, 4), (0, 0)]) >>> minimum_clearance(polygon) 2.0 >>> minimum_clearance(Polygon()) inf >>> minimum_clearance(None) nan
