6 Nominatim (from the Latin, 'by name') is a tool to search OpenStreetMap data
7 by name and address (geocoding) and to generate synthetic addresses of
8 OSM points (reverse geocoding). An instance with up-to-date data can be found
9 at https://nominatim.openstreetmap.org. Nominatim is also used as one of the
10 sources for the Search box on the OpenStreetMap home page.
