Semi-detailed digital geological map data based on BGS's National Grid 1:25 000 scale mapping with updated nomenclature.

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.

Recently new mapping has been captured in the small areas where 1:50 000 BGS Geology is absent. This has been digitised and is available at 1:25 000 scale.

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.
