BGS Geology 50k Mass Movement version 9
Data identifying landscape areas (shown as polygons) attributed with type of mass movement e.g. landslip. The data is presented at 1:50 000 scale. Onshore coverage is provided for England, Scotland, Wales and the Isle of Man. Approximately 99% coverage is available and BGS is committed to completing the coverage, and ongoing updates as part of its ongoing national survey. Mass movement describes areas where deposits have moved down slope under gravity to form landslips. These landslips can affec

Useful for
- Use cases llm-inferred
- Desk-study landslip and subsidence screening across a development site or route corridor · Ground stability constraints mapping for linear infrastructure route options · Initial geohazard scoping to inform the scope of ground investigation
- Audience llm-inferred
- geotechnical engineers · engineering geologists · civil engineers · planners
Limitations
- Constraints docs-verified
- Not site-specific: mapped at 1:50 000 scale · Approximately 99% onshore coverage, not complete · Historically not all mass movement events were recorded; ground conditions may have changed since release · Reuse restricted by BGS data licence and NERC copyright · Distributed as ESRI shapefiles only; no API or MCP access listed
