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 https://nominatim.openstreetmap.org. Nominatim is also used as one of the sources for the Search box on the OpenStreetMap home page.
The documentation of the latest development version is in the
docs/ subdirectory. A HTML version can be found at
Detailed installation instructions for the development version can be found at nominatim.org as well.
A quick summary of the necessary steps:
mkdir build cd build cmake .. make
Get OSM data and import:
./build/utils/setup.php --osm-file <your planet file> --all
Point your webserver to the ./build/website directory.
