To learn more, see our tips on writing great answers. Okay, here I'm confused. Lastly, I use the Geopandas distance function to calculate the distance to the nearest restaurant for each Block centroid. This is a pretty good blog post showing how to use GeoPanda's sindex (spatial index), which is based on Rtree (which is an optional dependency for GeoPandas). One polygon is selected in ArcGIS but not in GeoPandas as the distance there is > 10 km. You need to feed a singular Point object to the distance method: from shapely.geometry import Point from geopandas import GeoDataFrame destination = Point (5, 5) geoms = map (lambda x: Point (*x), [ (0, 0), (3, 3), (4, 1), (8, 2), (1, 10)]) departures = GeoDataFrame ( {'city': list ('ABCDE'), 'geometry': geoms}) print (departures.assign We can also check two GeoSeries against each other, row by row.
