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. It only takes a minute to sign up. It is also faster than using shapely's nearest_points with RTree (the spatial index method available via geopandas) because cKDTree allows you to vectorize your search whereas the other method does not.

One polygon is selected in ArcGIS but not in GeoPandas as the distance there is > 10 km. An object is said to intersect other if its boundary and interior intersects in any way with those of the other. To calculate a distance in meters, you would need to either use the Great-circle distance or project them in a local coordinate system to approximate the distance with a good precision. PyData Sphinx Theme Your points are in a lon, lat coordinate system (EPSG:4326 or WGS 84). We can either align both GeoSeriesbased on index values and use elements with the left_df geometry column.
