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.

BGS Geology 10K
Our most detailed dataset is provided at 1:10 000 and 1:25 000 scale. This digital geological data is based on BGS’s highest-resolution survey mapping. Many urban centres and transport routes are covered by this dataset. Lithostratigraphic nomenclature is updated to current usage.
BGS Geology 50K
This generalised digital geological data is based on BGS’s 1:50 000 and 1:63 360-scale maps. Covering almost all of Great Britain, it provides a detailed local to regional description of geology and underpins many of our national map services and products. Lithostratigraphic nomenclature is updated to current usage.
BGS Geology 625K
This generalised digital geological dataset is based on our published ‘poster’ maps of the UK (north and south). This dataset covers all of Great Britain and includes additional map data from Northern Ireland. It provides an excellent national overview of the UK’s geology and is commonly used as a teaching resource.
