Nominatim (from the Latin, 'by name') is a tool to search OpenStreetMap data by name and address (geocoding) and to generate synthetic addresses of OSM points (reverse geocoding). An instance with up-to-date data can be found at Nominatim is also used as one of the sources for the Search box on the OpenStreetMap home page and powers the search on the MapQuest Open Initiative websites.


More information about Nominatim, including usage and installation instructions, can be found in the docs/ subdirectory and in the OSM wiki at:


There are detailed installation instructions in the /docs directory. Here is a quick summary of the necessary steps.
