BGS Geology - 625k (DiGMapGB-625) Linear version 5

Data identifying linear features (shown as polylines) representing geological faults at the ground or bedrock surface (beneath superficial deposits). The scale of the data is 1:625 000 scale providing a simplified interpretation of the linear features and may be used as a guide at a regional or national level, but should not be relied on for local geology. Onshore coverage is provided for all of England, Wales, Scotland, the Isle of Man and Northern Ireland. Geological faults occur where a body of bedrock has been fractured and displaced by large scale processes affecting the earth's crust (tectonic forces). The digital data are attributed by fault type; two categories of fault are described in the data: fault at rockhead (representing normal dip-slip and strike-slip faults) and thrust fault (representing faults caused by compressive forces). The data has been generalised and shows only the location of major faults. The data are available in vector format (containing the geometry of each feature linked to a database record describing their attributes) as ESRI shapefiles and are delivered free of charge under the terms of the Open Government Licence.

Statement: The version 5 data of the 1: 625 000 linear features data was created primarily from the 1:50 000 scale Digital Geological Map of Great Britain (DiGMapGB-50) version 3 dataset (released in 2006) by generalisation involving cartographic selection, modification, simplification or exaggeration and matches that shown on the BGS poster maps of the UK (North and South) published in 2008. The attributes and nomenclature used follow those on the printed maps. The linear features were fitted to a relevant topographic base at the time of production.
