WebI'm looking to find, for each Census Block centroid, the distance to it's closest restaurant. I'm going to be slightly more general (because I already have this code written down) and do a distance from points to lines, but the same code should work from points to points or from polygons to polygons. @E.Coms it seems to be a correction to the accepted answer - the accepted answer actually does not work for me and this one does. An object is said to intersect other if its boundary and interior intersects in any way with those of the other. equidistant (in this case zero because they intersect). gdf2['dist'] = [geom.distance(gdf.geometry[0].boundary) for geom in gdf2.geometry] # or gdf2['dist'] = gdf2.apply(lambda x: x.geometry.distance(gdf.geometry[0].boundary), axis=1) For the correct Euclidean distance value in meters, you need to change the projection of the GeoDataFrame ( EPSG:32643 5 Ways to Connect Wireless Headphones to TV.
