示例

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

>>> s.extract_unique_points()
0    MULTIPOINT ((0 0), (1 1))
1    MULTIPOINT ((0 0), (1 1))
