Data identifying landscape areas (shown as polygons) attributed with geological names. The scale of the data is 1:250 000 scale providing a generalised geology. Onshore coverage is provided for all of England, Wales, Scotland and the Isle of Man. Data are supplied as two themes: bedrock and linear features (faults), there is no superficial, mass movement or artificial theme available onshore at this scale. Bedrock geology describes the main mass of solid rocks forming the earth's crust. Bedrock is present everywhere, whether exposed at surface in outcrops or concealed beneath superficial deposits or water bodies. Geological names are based on the lithostratigraphic or lithodemic hierarchy. This means rock bodies are arranged into units based on rock-type and geological time of formation. Where rock-types do not fit into the lithostratigraphic scheme, for example intrusive, deformed rocks subjected to heat and pressure resulting in new or changed rock types; then their classification is based on their rock-type or lithological composition. This assesses visible features such as texture, structure, mineralogy. Data identifying linear features (shown as polylines) represent geological faults at the ground or bedrock surface (beneath superficial deposits). 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 faults theme defines geological faults (shown as polylines) at the ground or bedrock surface (beneath superficial deposits). 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.
