Webb10 nov. 2024 · Try doing gdf.explode() to convert any multipart geometries to single part before your for loop.. From the documentation: GeoDataFrame.explode(self) Explode muti-part geometries into multiple single geometries. Each row containing a multi-part geometry will be split into multiple rows with single geometries, thereby increasing the vertical size … WebbIn mathematics, the symmetric difference of two sets, also known as the disjunctive union, is the set of elements which are in either of the sets, but not in their intersection. For example, the symmetric difference of the sets and is . The symmetric difference of the sets A and B is commonly denoted by or [1] [2] [3]
