Generalised digital geological map data based on BGS’s Universal Transverse Mercator (UTM) series of 1:250 000-scale maps reclassified with lithostratigraphic nomenclature. These maps were mostly published between 1977 and 1993.
Many BGS geology maps are now available digitally. The Digital Geological Map of Great Britain project (formerly known as 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.

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 two themes: bedrock geology and faults.
Geological maps are the foundation for many other types of earth science-related maps and are of potential use to a wide range of customers.
