GeoDataFrame.polygonize

Create polygons formed from the linework of a GeoSeries. Polygonizes the GeoSeries that contain linework which represents the edges of a planar graph. All geometries within the GeoSeries are considered together and the resulting polygons therefore do not map 1:1 to input geometries.

Signature

polygonize(node=True, full=False)

Parameters

bool

default:"True"

If True, the linework is noded together before polygonizing.

bool

default:"False"

If True, return the full polygonization result including cut edges, dangles, and invalid rings. Not supported in Sedona; passing True will raise NotImplementedError.

Returns

GeoSeries

Examples

>>> from sedona.spark.geopandas import GeoSeries
>>> from shapely.geometry import MultiLineString
>>> s = GeoSeries(
...     [
...         MultiLineString(
...             [[(0, 0), (0, 1), (1, 1)], [(1, 1), (1, 0), (0, 0)]]
...         ),
...     ]
... )
>>> s.polygonize()
0    POLYGON ((0 0, 0 1, 1 1, 1 0, 0 0))
