shapely.get_coordinate_dimension

get_coordinate_dimension(geometry, **kwargs)

Returns the dimensionality of the coordinates in a geometry (2 or 3).

Returns -1 for missing geometries (None values).

Note that with GEOS < 3.12, if the first Z coordinate equals nan, this function will return 2.

Parameters:

geometryGeometry or array_like

**kwargs

See NumPy ufunc docs for other keyword arguments.

Examples

>>> from shapely import Point
>>> get_coordinate_dimension(Point(0, 0))
2
>>> get_coordinate_dimension(Point(0, 0, 1))
3
>>> get_coordinate_dimension(None)
-1
