User guide : BGS Geology 10k-25k v3

BGS Geology 10k-25k v3 (formerly known as DiGMapGB -10) is the most detailed geological dataset produced by the British Geological Survey (BGS) and is based on our highest-resolution survey mapping. It is provided at 1:10 000 scale but contains a small proportion of 1:25 000 scale data in some upland areas (which was previously published as DiGMapGB-25). These digital geological maps are based on our previously published paper maps. BGS Geology 10k-25k v3 has an incomplete coverage but does include many urban centres and transport routes in Great Britain making it of potential use to a wide range of customers. Work is ongoing to digitise and publish our remaining paper map archive and ongoing survey programme. The maps are attributed with descriptions relating to geological age (lithostratigraphy), mode of emplacement (lithodemic origin), and composition (rock type or lithology). This information is arranged into five components that make up a typical geological map (as available): bedrock geology; superficial deposits; mass movement deposits, artificial ground, and linear features. The information provided in this User Guide is intended to give an overview to using and understanding this BGS Geology 10k-25k v3 data product.
