BGS DiGMapGB - 250
The DiGMapGB - 250 data is 1:250,000 scale digital geological mapping. The data is available in the Geology maps service as the 40 x 40 km view with Ordnance Survey's Strategi® data as the backdrop and also in 16 x 16 km view with Ordnance Survey's Meridian TM data mapping. It is also available to download in ESRI Shapefile and MapInfo MID /MIF formats as standard 100 x 100km OS tiles (for example TQ). The data covers all of Scotland, England and Wales onshore areas.
The data comprises of polygons (or areas) and lines. Each polygon is attributed with information based on the name (often lithostratigraphical) of the unit and its lithology or composition. The polygons are arranged into a single layer of bedrock geology ('solid'). The linear features area also available as a single layer comprising of faults and the coastline.
Each DiGMapGB-250 digital data is based on the latest BGS 1:250 000 scale UTM (Universal Transverse Mercator projection) Bedrock or 'Solid' geological map. The digital data have a lithostratigraphic nomenclature rather than a chronostratigraphic classification usually found on the paper maps.
Further information on DiGMapGB - 250 is available to registered users within the Digimap service.
