Subsidence Maps & Data
There is a rise in the public’s knowledge and understanding of the affect of ground conditions on the safety of property and subsequent implications on value. Information about geological hazards is vital for the identification of areas with the potential for ground movement.
Today, a broad range of maps and data is available for the visualisation and analysis of ground movement risk. This is available as vector data, 25m grid data or as a postcode based database. A series of GIS (Geographical Information System) map layers show the most significant hazard areas. The subsidence related hazards include: landslides, shrink-swell clays, soluble rocks, running sands, compressible ground and collapsible deposits.
