BGS Geology 10k - 25k (DiGMapGB-10 & DiGMapGB-25) version 3

The BGS GeologyGB10-25 datasets are a digital representation of the geological maps of Great Britain at 1:10 000 and 1:25 000 scale. This is the base scale at which BGS surveys, and the dataset covers up to 52% of Great Britain published at 1: 10 000 and 1:25 000 scale. The content is derived from the surveyed and published maps together with additional new survey at those scales. BGS Geology10-25 V3.25 dataset includes 4 geological themes and 1 map component (4 polygon and 1 linear), providing

Resolution docs-verified: Map scale 1:10 000 and 1:25 000 (vector)
Update frequency docs-verified: As needed (asNeeded); not on a fixed schedule
Formats docs-verified: ESRI Shapefile (vector)
Access docs-verified: Available under BGS data licence. Copyright vested in NERC; no part may be reproduced or transmitted without prior permission of the copyright holder (via BGS Intellectual Property Rights Manager).

Useful for

Use cases llm-inferred: Desk-study geology baseline for ground investigation scoping across GB at 1:10 000 / 1:25 000 · Screening for artificial ground and landslip (mass movement) constraints on development sites · Superficial deposit mapping to support infiltration / SuDS suitability screening · Geological input layer for geotechnical and foundation risk assessments in GIS
Audience llm-inferred: geotechnical engineers · civils engineers · hydrogeologists · environmental consultants · planners · GIS analysts

Limitations

Constraints llm-inferred: Snapshot in time; artificial ground and land use can change rapidly, so data may become dated quickly · Mass movement records reflect data regarded as at 2008; significant changes may have occurred since · Covers only up to 52% of Great Britain at these scales · Reproduction and redistribution restricted by NERC/BGS copyright; use is at the customer's own risk with no warranty of accuracy or suitability · Docs describe both 4 themes plus 1 map component and 'five data themes'; confirm the theme count against the shapefiles · Vector shapefile only; no API or MCP access described
