GeoDataFrame.union_all

Returns a geometry containing the union of all geometries in the GeoSeries. Sedona does not support the method or grid_size argument, so the user does not need to manually decide the algorithm being used.

Signature

union_all(method='unary', grid_size=None) -> BaseGeometry

Parameters

str (default ``'unary'``)

default:"'unary'"

Not supported in Sedona.

float

default:"None"

Not supported in Sedona.

Examples

>>> from sedona.spark.geopandas import GeoSeries
>>> from shapely.geometry import box
>>> s = GeoSeries([box(0, 0, 1, 1), box(0, 0, 2, 2)])
>>> s
0    POLYGON ((1 0, 1 1, 0 1, 0 0, 1 0))
1    POLYGON ((2 0, 2 2, 0 2, 0 0, 2 0))
dtype: geometry

>>> s.union_all()
<POLYGON ((0 1, 0 2, 2 2, 2 0, 1 0, 0 0, 0 1))>
