Reverse Geocode Coordinates to the Nearest Address or Place (Photon, OpenStreetMap)

photon/reverse-geocode

Turn a latitude and longitude into the nearest address or place with the Photon geocoder over OpenStreetMap: each match as a GeoJSON feature with its coordinates, name, street, house number, postcode, city, state, country and OSM type and id. Names in the local language by default, or English, German or French. Up to 20 results, nearest first; a point with nothing nearby, such as open ocean, returns an empty list. © OpenStreetMap contributors (ODbL); cached for one hour.
