Copyright and License OpenStreetMap is open data, licensed under the Creative Commons Attribution-ShareAlike 2.0 licence (CC BY-SA). You are free to copy, distribute, transmit and adapt our maps and data, as long as you credit OpenStreetMap and its contributors. If you alter or build upon our maps or data, you may distribute the result only under the same licence. The full legal code explains your rights and responsibilities.

How to credit OpenStreetMap If you are using OpenStreetMap map images, we request that your credit reads at least &ldquo;&copy; OpenStreetMap contributors, CC BY-SA&rdquo;. If you are using map data only, we request &ldquo;Map data &copy; OpenStreetMap contributors, CC BY-SA&rdquo;. Where possible, OpenStreetMap should be hyperlinked to http://www.openstreetmap.org/ and CC BY-SA to http://creativecommons.org/licenses/by-sa/2.0/. If you are using a medium where links are not possible (e.g. a  printed work), we suggest you direct your readers to  www.openstreetmap.org (perhaps by expanding  &lsquo;OpenStreetMap&rsquo; to this full address) and to  www.creativecommons.org.

Finding out more Read more about using our data at the Legal FAQ. OSM contributors are reminded never to add data from any copyrighted sources (e.g. Google Maps or printed maps) without explicit permission from the copyright holders. Although OpenStreetMap is open data, we cannot provide a free-of-charge map API for third-party developers.

See our API Usage Policy, Tile Usage Policy and Nominatim Usage Policy.

Our contributors Our CC BY-SA licence requires you to &ldquo;give the Original Author credit reasonable to the medium or means You are utilising&rdquo;. Individual OSM mappers do not request a credit over and above that to &ldquo;OpenStreetMap contributors&rdquo;, but where data from a national mapping agency or other major source has been included in OpenStreetMap, it may be reasonable to credit them by directly reproducing their credit or by linking to it on this page.
