Geology 50K

The 1:50 000-scale geological maps for England, Wales and Scotland are available digitally as part of the digital geological map of Great Britain dataset (BGS Geology 50K) and are made available here to view as a WMS service.

Layers for bedrock, superficial deposits, artificial ground, mass movement and geological linear features are included in the service.

This service is also included in the OneGeology project’s data portal.
