Nominatim
=========

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.

        ./nominatim-venv/bin/pip install packaging/nominatim-{api,db}

3. Create a project directory, get OSM data and import:

        mkdir nominatim-project
        cd nominatim-project
        ../nominatim-venv/bin/nominatim import --osm-file <your planet file> 2>&1 | tee setup.log
