geopandas.GeoSeries.explode

GeoSeries.explode(ignore_index=False, index_parts=None)

Explode multi-part geometries into multiple single geometries.

Single rows can become multiple rows. This is analogous to PostGIS’s ST_Dump(). The ‘path’ index is the second level of the returned MultiIndex

Parameters

ignore_indexbool, default False

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

index_partsboolean, default True

If True, the resulting index will be a multi-index (original index with an additional level indicating the multiple geometries: a new zero-based index for each single part geometry per multi-part geometry).

Returns

A GeoSeries with a MultiIndex. The levels of the MultiIndex are the

original index and a zero-based integer index that counts the

number of single geometries within a multi-part geometry.
