BGS Geology 10k - 25k (DiGMapGB-10 & DiGMapGB-25) Bedrock version 3
Data identifying landscape areas (shown as polygons) attributed with geological names and rock type descriptions. The scale of the data is 1:10 000 and 1:25 000 scale. Onshore coverage is partial with approximately 52% of England, Scotland, and Wales available in the version 3 data release. BGS intend to continue developing coverage at this scale; current focus is to include all large priority urban areas, along with road and rail transport corridors. Bedrock geology describes the main mass of s
