Calculating distance from centre of polygon to point using ArcGIS Desktop? WebTo find all polygons within a given distance of a point, for example, one can first use the buffer () method to expand each point into a circle of appropriate radius, then intersect those buffered circles with the polygons in question. Some geographic operations return normal pandas object. 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 Distance between the point of touching in three touching circles.
