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: landslides

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.

BGS GeoSure shrink–swell

Many soils contain clay minerals that absorb water when wet (making them swell), and lose water as they dry (making them shrink). Many of us see this in our gardens when the ground becomes cracked during the summer, yet becomes ‘heavy’ in the winter.

BGS GeoSure: collapsible deposits

The potential for collapsible ground to be a hazard has been assessed using 1:50 000 scale digital maps of superficial deposits.
