BGS Geology: onshore Digital Geological Map of Great Britain data

BGS Datasets

The BGS Geology datasets are digital geological maps of Great Britain based on the different series of published BGS geological maps. We currently offer digital data at 4 key scales: 1:10 000, 1:50 000, 1:250 000 and 1:625 000.

The larger scale maps provide detail for site-specific use; the medium to small scale maps provide national coverage. Ongoing revisions from our survey activities are updated on a regular basis.

Datasets and scales

BGS Geology 10k

Our most detailed dataset is provided at 1:10 000 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 BGS’s 1:250 000 scale bedrock-only maps. Data and lithostratigraphic re-classification are derived from maps published between 1977 and 1993.

BGS Geology 625k

This generalised digital geological data is based on BGS’s 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 geology and is commonly used as a teaching resource.
