overlay(df1, df2, how='intersection', make_valid=True, use_sindex=None)¶
Perform spatial overlay between two polygons.
Currently only supports data GeoDataFrames with polygons. Implements several methods that are all effectively subsets of the union.
df1 : GeoDataFrame with MultiPolygon or Polygon geometry column
df2 : GeoDataFrame with MultiPolygon or Polygon geometry column
how : string
Method of spatial overlay: ‘intersection’, ‘union’, ‘identity’, ‘symmetric_difference’ or ‘difference’.
df : GeoDataFrame
GeoDataFrame with new set of polygons and attributes resulting from the overlay
