geopandas.GeoSeries.normalize#

GeoSeries.normalize()[source]#

Returns a GeoSeries of normalized geometries to normal form (or canonical form).

This method orders the coordinates, rings of a polygon and parts of multi geometries consistently. Typically useful for testing purposes (for example in combination with equals_exact).

Examples

>>> from shapely.geometry import Polygon, LineString, Point
>>> s = geopandas.GeoSeries(
...     [
...         Polygon([(0, 0), (1, 1), (0, 1)]),
...         LineString([(0, 0), (1, 1), (1, 0)]),
...         Point(0, 0),
...     ],
... )
>>> s
0    POLYGON ((0 0, 1 1, 0 1, 0 0))
1        LINESTRING (0 0, 1 1, 1 0)
2                       POINT (0 0)
dtype: geometry

>>> s.normalize()
0    POLYGON ((0 0, 0 1, 1 1, 0 0))
1        LINESTRING (0 0, 1 1, 1 0)
2                       POINT (0 0)
