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 http://nominatim.openstreetmap.org. 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 OSM wiki at:
The following instructions is a quick guide to installation. A more detailed guide
how to set up your own instance of Nominatim can be found in the wiki:
