The BGS GeoSure 5 km hex grid datasets provide a generalised overview of the susceptibility to six naturally occurring geohazards in Great Britain. The hexagon grid provides a national-scale summary of the GeoSure data product. The detailed GeoSure dataset is also available to licence and provides further detail at a scale of 1:50 000.
The 5 km hex grid data has been generalised into a vector map of interlocking hexagon cells (a side length of 5 km), with an area approximately 65 km2. There are three classes included within the data: low, moderate and significant.
The six layers of data provided are as follows:
- BGS GeoSure: collapsible deposits
- BGS GeoSure: compressible ground
- BGS GeoSure: landslides
- BGS GeoSure: running sand
- BGS GeoSure: shrink–swell
- BGS GeoSure: soluble rocks

The potential for landsliding (slope instability) to be a hazard has been assessed using 1:50 000 scale digital maps of superficial and bedrock deposits. These have been combined with information from the BGS National Landslide Database and scientific and engineering reports.
