Nominatim

Open-source geocoding and reverse geocoding from OpenStreetMap data

About Nominatim

Nominatim uses OpenStreetMap data to find locations on Earth by name and address, and can also reverse the process, finding an address for any coordinate on the planet. It powers the search box on the official OpenStreetMap site, serving tens of millions of queries per day, and supports free-form queries in any language as well as structured queries for bulk geocoding. Installations scale from a laptop serving one city to a planet-wide server.
