5 methods： osmnx.geometries.geometries_from_address(address, tags, dist=1000) osmnx.geometries.geometries_from_bbox(north, south, east, west, tags) osmnx.geometries.geometries_from_place(query, tags, which_result=None, buffer_dist=None) osmnx.geometries.geometries_from_point(center_point, tags, dist=1000) osmnx.geometries.geometries_from_polygon(polygon, tags) tags tags = {"building": True} would return all building footprints in the area tags = {"amenity":True, "landuse":["retail","commercial"], "highway":"bus_stop"} would return all amenities, landuse=retail, landuse=commercial, and highway=bus_stop.
