shapely.within#
- within(a, b, **kwargs)#
Return True if geometry A is completely inside geometry B.
A is within B if no points of A lie in the exterior of B and at least one point of the interior of A lies in the interior of B.
- Parameters:
- a, bGeometry or array_like
Geometry or geometries to check.
- **kwargs
See NumPy ufunc docs for other keyword arguments.
