geopandas.GeoSeries.get_coordinates

GeoSeries.get_coordinates(include_z=False, ignore_index=False, index_parts=False)

Gets coordinates from a GeoSeries as a DataFrame of floats.

The shape of the returned DataFrame is (N, 2), with N being the number of coordinate pairs. With the default of include_z=False, three-dimensional data is ignored. When specifying include_z=True, the shape of the returned DataFrame is (N, 3).

Parameters:

include_zbool, default False

Include Z coordinates

ignore_indexbool, default False

If True, the resulting index will be labelled 0, 1, …, n - 1, ignoring index_parts.

index_partsbool, default False

If True, the resulting index will be a MultiIndex (original index with an additional level indicating the ordering of the coordinate pairs: a new zero-based index for each geometry in the original GeoSeries).

Returns:

pandas.DataFrame
