Generalised digital geological map data based on BGS's New Series 1:50 000 and 1:63 360 scale (one-inch to one-mile) maps with updated nomenclature. Includes a few 1:100 000 scale maps of Orkneys and Hebrides

Many BGS geology maps are now available digitally. The Digital Geological Map of Great Britain project (DiGMapGB) has prepared 1:625 000, 1:250 000, 1:50 000 and 1:10 000 scale datasets for England, Wales and Scotland. Work continues to upgrade these.

Many existing 'paper-only' maps have been digitised, and the nomenclature, particularly of older maps, updated to current usage.

The geological areas (or polygons) are labelled or attributed with a name (based on their lithostratographical, chronostratographical or lithodemic nomenclature) and their composition (rock type or lithology). This information is arranged in up to four themes as available: bedrock geology; superficial deposits; mass movement; and artificial ground. Faults and other linear features are available in a separate theme.

Geology maps are the foundation for many other types of earth science related maps and are of potential use to a wide range of customers.
