BGS Geology - 250k (DiGMapGB-250) Linear version 4
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 1:250 000 scale providing a generalised set of linear features. Onshore coverage is provided for all of England, Wales, Scotland, and the Isle of Man. 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: contact and non-contact faults. Contact faults form a boundary between two different rock types whilst non-contact faults indicate a fault displacement within the same rock. The data has been generalised and shows only the location of major faults. All faults shown are inferred i.e. not exposed or seen at a locality, but derived from other evidence including linear depressions in the landscape, the truncation or displacement of topographical features. 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 available under BGS data licence.

Each DiGMapGB-250 digital tile is based on the latest BGS 1:250 000 scale UTM (Universal Transverse Mercator projection) bedrock or ‘solid’ geological map. This series was originally published between 1977 and 1993. Most of the onshore areas were compiled in the 1980s and are based, primarily, on earlier more detailed 1:50 000 (and one-inch to one-mile) geological maps published in the preceding decades and dating from the 1870s through to the 1980s. The source 1:250 000 published maps have a chronostratigraphical classification but were reclassified, as far as possible, with a lithostratigraphical nomenclature for the digital data. Some changes were made to the published lines to correct errors, improve the fit between maps, add formational boundaries or remove purely chronostratigraphical ones. The sources of information specific to each digital tile are available. The generalised geological lines were fitted to topographical bases compiled from Ordnance Survey 1:250 000 maps and Ministry of Defence, Joint Operations Graphic (JOG) sheets. The UTM series sheets were scanned and re-projected to OS British National Grid for digitising. The digital data were re-tiled in to 100 km squares and re-fitted to OS Strategi coastline and RCS codes added for version 4, released 2005.
