Fast Reverse Geocoder Lite - A simple but fast reverse geocoding API up to city granularity level. Convert a geographic coordinate (latitude and longitude) into city, neighborhood name, wikipedia, wikidata, geocode, elevation, timezone, country, region and OSM tags. This reverse geocoding API is ideal for applications which process location data (for example mobile GPS data) and need to correlate this quickly with real place names. It takes as input a Latitude, Longitude pair, and outputs either XML (default) or JSON text with the name of the nearest city/neighborhood and other regional information based on both Geonames.org and OpenStreetMap.org regional/city/neighborhood polygons. Send a reverse geocoding request as per API spec: /latitude,longitude e.g., http://13.235.89.72/51.4647,0.0079 (XML output - Default) or http://13.235.89.72/51.4647,0.0079.json (JSON output) Sample XML output: 51.4647 0.0079 33 Europe/London Blackheath Blackheath England Greater London UK 51.4647 0.0079 BLKHYTH-KHBKK 0.000 en:London Borough of Lewisham Q215030 https://www.lewisham.gov.uk/ OS_OpenData_CodePoint Codelist.txt London Borough of Lewisham 00AZ 8 inner_london_borough E09000023 GB-LEW administrative Lewisham Council boundary UK 51.50853 -0.12574 25 Europe/London London London England Greater London UK 51.4647 0.0079 10.458 LONDON-KHBKK 3154700123754 LONDON-MULUA-PAULENI Most columns are self explanatory.
