geopandas.overlay

geopandas.overlay(df1, df2, how='intersection', make_valid=True, keep_geom_type=True)

Perform spatial overlay between two polygons.

Currently only supports data GeoDataFrames with polygons. Implements several methods that are all effectively subsets of the union.

Parameters

df1GeoDataFrame with MultiPolygon or Polygon geometry column

df2GeoDataFrame with MultiPolygon or Polygon geometry column

howstring

Method of spatial overlay: ‘intersection’, ‘union’, ‘identity’, ‘symmetric_difference’ or ‘difference’.

keep_geom_typebool

If True, return only geometries of the same geometry type as df1 has, if False, return all resulting gemetries.

Returns

dfGeoDataFrame

GeoDataFrame with new set of polygons and attributes resulting from the overlay
