shapely.normalize

normalize(geometry, **kwargs)

Convert Geometry to strict normal form (or canonical form).

In strict canonical form, the coordinates, rings of a polygon and parts of multi geometries are ordered consistently. Typically useful for testing purposes (for example in combination with equals_exact).

Parameters:

geometryGeometry or array_like

Geometry or geometries to normalize.

**kwargs

See NumPy ufunc docs for other keyword arguments.

Examples

>>> from shapely import MultiLineString
>>> line = MultiLineString([[(0, 0), (1, 1)], [(2, 2), (3, 3)]])
>>> normalize(line)
<MULTILINESTRING ((2 2, 3 3), (0 0, 1 1))>
