shapely.dwithin#
- dwithin(a, b, distance, **kwargs)#
Returns True if the geometries are within a given distance.
Note
‘dwithin’ requires at least GEOS 3.10.0.
Using this function is more efficient than computing the distance and comparing the result.
- Parameters:
- a, bGeometry or array_like
- distancefloat
Negative distances always return False.
- **kwargs
See NumPy ufunc docs for other keyword arguments.
