The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) relation 62149 is a country in Europe consisting the 'British Isles' (England, Scotland, and Wales), Northern Ireland, and British Crown Dependencies relation 9110397 (the Isle of Man relation 62269, Guernsey relation 270009 and Jersey relation 367988 'The Channel Islands') and British Overseas Territories relation 3969434.

The term Britain is confusing, even to those who live here, as it is often used as a synonym for the UK.

The UK has a very strong history in OSM: OpenStreetMap itself was born here in 2004; The very first mapping party was held in Limehouse, London 2005; and we have been host to 2 SotM conferences: State Of The Map 2007 and State Of The Map 2013.


At the national level OSMUK (osmuk.org) is a non-profit company and registered Local Chapter of the OpenStreetMap Foundation. OSMUK's roles are to act as a focus for community, be a financial entity, give the community representation at national level infrastructure meetings, run regional events, and provide advice and assistance to organisations and companies wishing to add to or use OpenStreetMap. They maintain a Talent Directory for professional and voluntary service providers.

There is an active online community participating in the Talk-GB mailing list (historic archive).

For geographically pragmatic reasons, Northern Ireland matters are mainly discussed on the Talk-IE mailing list (historic archive).


There are 4 regional groups with active online and regular monthly in-person meetups:

For East Midlands see the National Events list. For London see the OSM London page. For Scotland see the OSM Scotland page. For Birmingham area see the Mappa Mercia page and mailing list.

Third party data

In addition to the world-wide data sources, the following are available specifically for mapping in the UK. Please note that their accuracy varies and therefore where possible we prefer ground-truthed data (e.g. collected by GPS survey)

  • Ordnance Survey (Great Britain only)
    • Ordnance_Survey_Opendata - Ordnance Survey has released some data that can be used as an additional source of reference when mapping.
    • Old OS maps - Old maps that are out of copyright and have been scanned and rectified for tracing (work ongoing).
  • Natural England England only
    • OGL data for National Parks, Local and National Nature Reserves, Commons
