BGS Geology 10k - 25k (DiGMapGB-10 & DiGMapGB-25) Superficial 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. Superficial deposits are the youngest geolog

Useful for

Use cases llm-inferred: Superficial geology baseline for desk studies and ground investigation scoping in covered areas · Infiltration and SuDS screening using superficial deposit types (gravel, sand, silt, clay) · Geotechnical desk study along road and rail corridors and in priority urban areas, where coverage is focused
Audience llm-inferred: geotechnical engineers · hydrogeologists · civils engineers · drainage engineers · GIS analysts · environmental consultants

Limitations

Constraints docs-verified: Onshore coverage is partial (about 52% of England, Scotland and Wales); BGS plans to extend it · Current focus is large priority urban areas and road and rail corridors · Distributed as shapefiles only; no API or tool access listed in docs · Reuse is restricted by BGS/NERC copyright and licence terms · NERC/BGS gives no warranty on quality or accuracy; use is at the customer's own risk
