Details

The Ordnance Survey's OpenData suite of digital products includes 1:250,000 scale raster mapping for all of Great Britain, and additional national mapping at higher resolution (OS StreetView and OS VectorMap District). These products are actively maintained. As Ordnance Survey is the national mapping agency for Great Britain only, the coverage excludes Northern Ireland, the Isle of Man and the Channel Islands. Open data mapping for those parts of the UK is not currently available at resolutions of 1:250,000 or better. The Ordnance Survey's OpenData product suite includes mapping with better than 1:250,000 resolution (OS Street View) and is released under the OS OpenData Licence, which complies with the Open Definition. The mapping is updated regularly (most recently in May 2012).
