Datasets

The BGS corrosivity dataset is a GIS layer supporting the management of underground iron assets that has been created in response to the growing awareness of the cost of maintenance of structures such as pipelines and building foundations.

The BGS Geology datasets are digital geological maps of Great Britain based on the different series of published BGS geological maps.

The BGS GeoSure datasets identify areas of potential hazard and, therefore, potential natural ground movement, in Great Britain.

The Debris Flow landslide layer provides information on the potential of the ground, at a given location, to form a debris flow. It is based on a combination of digital geological, hydrogeological and topographic data.

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.

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.

The shrink–swell 3D data is a regional hazard susceptibility map that identifies areas of potential shrink–swell hazard in 3D at intervals down to 20 m in the London and Thames Valley area.

This is a single data layer that identifies areas of potential shrink–swell hazard that are underneath another solid formation and therefore hidden from the surface.

Ground dissolution occurs when water passing through soluble rocks produces underground cavities and cave systems. These cavities reduce support to the ground above and can cause localised collapse of the overlying rocks and deposits.
