A tool for building a database of OpenStreetMap for geocoding and for searching the database. Database backend.

Nominatim - DB Backend

Nominatim is a tool to search OpenStreetMap data by name and address (geocoding) and to generate synthetic addresses of OSM points (reverse geocoding).

This module implements the database backend for Nominatim and the command-line tool for importing and maintaining the database.

Installation

Prerequisites

Nominatim requires osm2pgsql (>=1.8) for reading OSM data and PostgreSQL (>=9.6) to store the data.

On Ubuntu (>=23.04) and Debian (when using backports), you can install them with:

sudo apt-get install osm2pgsql postgresql-postgis

Installation from pypi

To install Nominatim from pypi, run:

pip install nominatim-db

Quick start

First create a project directory for your new Nominatim database, which is the space for additional configuration and customization:

mkdir nominatim-project

Make sure you run all nominatim commands from within the project directory:

cd nominatim-project

Download an appropriate data extract, for example from Geofabrik and import the file:

nominatim import --osm-file <downlaoded-osm-data.pbf>

You will need to install the nominatim-api package to query the database.
