shapely.relate#

relate(a, b, **kwargs)#

Return a string representation of the DE-9IM intersection matrix.

If you need to test multiple geometries against the same geometry A, you can improve performance by preparing A in advance using prepare().

Parameters:
a, bGeometry or array_like

Geometry or geometries to check.

**kwargs

See NumPy ufunc docs for other keyword arguments.

See also

prepare

improve performance by preparing a (the first argument)

relate_pattern

check if the DE-9IM relationship code satisfies a pattern

Examples

>>> import shapely
>>> from shapely import LineString, Point
>>> point = Point(0, 0)
>>> line = LineString([(0, 0), (1, 1)])
>>> shapely.relate(point, line)
