A geospatial dataset from the British Geological Survey (BGS) provides a generalized assessment of potential ground movement due to soil shrink-swell behavior across Great Britain. The data is aggregated to a 5km hexagonal grid, with each cell rated Low (1), Moderate (2), or Significant (3) based on the highest susceptibility found within it. The dataset, version 8, was last updated on 2026-04 09.
Use Cases
- Regional hazard mapping for construction planning based on the aggregated susceptibility ratings.
- Prioritizing areas for detailed geotechnical investigation based on the 'Significant' rating flags.
- Informing sustainable land management solutions based on the underlying geological and clay mineral behavior research.
Strengths
- Provides complete national coverage for Great Britain.
- Ratings are derived from the BGS Digital Map (DiGMapGB-50) and expert knowledge of geological formations.
- Data is generalized to a user-friendly 5km hexagonal grid format for easier interpretation.
Limitations
- The summarising process via spatial statistics at this scale may lead to under or over estimation of the hazard extent.
- Column-level documentation is absent; field semantics must be inferred after download.
