Digital Geological Map Data of Great Britain - 25k (DiGMapGB-25) Mass Movement version 2
Data identifying landscape areas (shown as polygons) attributed with geological names. The scale of the data is 1:25 000 scale. Onshore coverage is partial and BGS has no intention to create a national coverage at this scale. Areas covered are essentially special areas of 'classic' geology and include Llandovery (central Wales), Coniston (Lake District) and Cuillan Hills (Isle of Skye). Mass movement describes areas where deposits have moved down slope under gravity to form landslips. These land

What's in it
- Data offered docs-verified
- mass movement (landslip) polygons attributed with geological names · foundered strata (ground collapse from subsidence) polygons · geological name attributes linked to each polygon
- Coverage docs-verified
- Great Britain, onshore partial coverage only; special areas of 'classic' geology (e.g. Llandovery, Coniston, Cuillan Hills); no national coverage planned at this scale · Snapshot as at 2008
- Resolution docs-verified
- 1:25 000 scale
- Update frequency docs-verified
- Not planned (no updates scheduled)
- Formats docs-verified
- ESRI shapefile
- Access docs-verified
- Available under BGS data licence; copyright vested in NERC, and reproduction or transmission requires prior permission from the BGS copyright holder. No API key or auth noted; pricing not stated.
Useful for
- Use cases llm-inferred
- Landslip and ground-collapse screening for site investigation scoping in classic geology areas · Desk study review of mapped mass movement and foundered strata near linear infrastructure route options · Geohazard context for flood and drainage assessments in covered areas (e.g. Llandovery, Lake District, Skye)
- Audience llm-inferred
- geotechnical engineers · engineering geologists · civils engineers · planners · GIS analysts
Limitations
- Constraints llm-inferred
- Onshore coverage is partial; not a national dataset · Snapshot as at 2008; landslip and subsidence conditions may have changed since · Map scale 1:25 000, so not suitable for site-specific detail without verification · Update frequency not planned · Licence restricts reproduction without BGS permission · Shapefile download only; no API or MCP access indicated
