The 1:25,000 scale Raster mapping has been updated in Digimap Roam, Carto and Data Download. This new data is the latest release by Ordnance Survey from May 2012. There has been quite a few changes with just under a third of the country seeing updates with this release.
Some of the areas with the most changes have been in the Scottish Highlands and the main London 2012 Olympic site in East London.
It is great to see (what looks like) the mapping completed for the site, and to compare how it has taken shape over the last year. Download the maps from Data Download to view the changes for yourself.
