Webbnearest(geometry) → Optional[Any] Return the index of the nearest geometry in the tree for each input geometry based on distance within two-dimensional Cartesian space. Note ‘nearest’ requires at least GEOS 3.6.0. This distance will be 0 when input geometries intersect tree geometries. Webb24 jan. 2024 · So the within method you are calling is the shapely's Point.within, which can only work with other scalar shapely geometries, and does not recognize a GeoSeries (and it is here that the error is coming from). The other way around, GeoSeries methods can work with both GeoSeries or shapely objects as argument. So you can invert the operation:
