WebWe can use geopandas’s R-tree spatial index to find which street intersections lie within the boundaries of the city: First we have our GeoDataFrame (called gdf) create an R-tree spatial index for its geometry. Then we intersect this index with the bounding box of our polygon. This returns a set of possible matches.
