Digital Geological Map Data of Great Britain - 625k (DiGMapGB-625) 2008

Data identifying landscape areas (shown as polygons) attributed with geological names. The scale of the data is 1:625 000 providing a simplified interpretation of the geology. Onshore coverage is provided for all of England, Wales, Scotland, the Isle of Man and Northern Ireland. Data are supplied as four themes: bedrock, superficial deposits, dykes and linear features (faults). Bedrock geology describes the main mass of solid rocks forming the earth's crust. Bedrock is present everywhere, whethe

Useful for

Use cases llm-inferred
Desk study bedrock and superficial geology baseline for ground investigation scoping · Screening faults and dykes as regional geological constraints at early site appraisal · Regional geological context for drainage or groundwater risk assessments before site-scale data is available
Audience llm-inferred
geotechnical engineers · hydrogeologists · civils engineers · environmental consultants · GIS analysts · planners

Limitations

Constraints llm-inferred
1:625 000 scale is a simplified interpretation, so not suitable for site-scale detail · Reference date 2008 and update frequency is as needed, so may not reflect recent mapping · Licence metadata is 'otherRestrictions'; licence text notes third-party IPR may apply and advises consulting BGS
