- API
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.

Generalised digital geological map data based on BGS’s published poster maps of the UK (north and south). Bedrock-related themes were created by generalisation of 1:50 000 data to make the 2007 fifth edition bedrock geology map. Superficial geology-related themes were digitised from the 1977 first edition Quaternary map (north and south).
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 superficial deposits. Faults and other linear features are available in a separate theme.

BGS Geology
The BGS Geology datasets are digital geological maps of Great Britain based on the different series of published BGS geological maps.
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 250K
This generalised digital geological data is based on our 1:250 000-scale, bedrock-only maps. Data and lithostratigraphic re-classifications are derived from maps published between 1977 and 1993.
