In 2000 BGS embarked on constructing a more comprehensive database of national karst information. The aim being to retrieve karst data from field slips and paper maps with additional fine-scale detail gathered during fieldwork, from remote sensing techniques such as LiDAR (light detection and ranging) and from existing documentary data sources such as historical and modern Ordnance Survey maps.
Glaciokarst is formed when karstification is affected by glacial processes, and usually occurs in areas with limestone. Nival karst is formed by the karstification in glacial and periglacial environments. Tropical karst occurs in warm climates, this type caused by great precipitation and evaporation.
