By using this database, we can build Garmin maps with 6 times more addresses than only OSM data.</div><div><br></div><div>It's built from various sources besides OSM data. Thanks to the land tax administration, we french OSM mappers have access to the complete "cadastre" (i.e. building shapes, street names and addresses) covering the entire country.<br>This information, with OpenData adresses and OSM data on the side, is now mashed up into the "BANO" database. 11+ million addresses have been matched to a street name in OSM, 1.4 million addresses are gathered from the OpenData files of several cities, 2.6 million come from OSM. Those numbers will improve over time, as this DB is not complete yet.<br>See a map at [1], green dots are OSM addresses, blue ones addresses matched to a street name, yellow dots are from OpenData files and red are addresses not yet matched to an existing street name.</div><div><div><br></div><div>How to add the addresses when creating Garmin maps ?<br>The data is available in CSV format, geographically split following the "département" boundaries (admin_level 6). The steps are : <br><div><div><ul><li>Download a fresh .pbf Geofabrik file of France (admin_level 2) or one of its "région" (admin_level 4)</li><li>Download the BANO CSV files covering the previously downloaded area</li><li>Merge the CSV files. </li><li>Filter address source to keep only matched addresses and OpenData addresses (blue and yellow dots).</li><li>Convert the CSV format to OSM format.</li><li>Merge the .osm file to the Geofabrik file.</li><li>Launch your usual map generation workflow with this new file.</li></ul></div></div><div><br></div><div>I wrote a shell script that does all of the above. It's published on <a href="https://github.com/PacoTyson/bano2garmin/">https://github.com/PacoTyson/bano2garmin/</a> and attached as a zip archive.</div><div></div></div></div></body></html>
