geopandas.GeoSeries.count_geometries#

GeoSeries.count_geometries()[source]#

Returns a Series containing the count of geometries in each multi-part geometry.

For single-part geometry objects, this is always 1. For multi-part geometries, like MultiPoint or MultiLineString, it is the number of parts in the geometry. For GeometryCollection, it is the number of geometries direct parts of the collection (the method does not recurse into collections within collections).

>>> s = geopandas.GeoSeries(
...     [
...         MultiPoint([(0, 0), (1, 1), (1, -1), (0, 1)]),
...         MultiLineString([((0, 0), (1, 1)), ((-1, 0), (1, 0))]),
...         LineString([(0, 0), (1, 1), (1, -1)]),
...         Point(0, 0),
