shapely.intersects

intersects(a, b, **kwargs)

Return True if A and B share any portion of space.

Intersects implies that overlaps, touches, covers, or within are True.

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.

disjoint

intersects(A, B) == ~disjoint(A, B)

prepare

improve performance by preparing a (the first argument)

intersects_xy

variant for checking against a Point with x, y coordinates

Examples

>>> import shapely
>>> from shapely import LineString, Point
>>> line = LineString([(0, 0), (1, 1)])
>>> shapely.intersects(line, Point(0, 0))
True
>>> shapely.intersects(line, Point(0, 1))
False
>>> shapely.intersects(line, LineString([(0, 2), (2, 0)]))
True
>>> shapely.intersects(None, None)
False
