This service is an INSPIRE download WFS service, providing UK onshore bedrock geological data at 1:625 000 scale. This map data is collected as part of an ongoing BGS project: Digital Geological Map of Great Britain (DiGMapGB). GeoServer software is used to provide this WFS service. This service is delivering MappedFeatures specified by GeologicUnits, the geological history of which is recorded by GeologicEvents.
BGS offshore marine products are made available to view via this web map service. The 1:250 000 scale offshore geological maps in the UTM series (Universal Transverse Mercator projection) are available digitally as two themes: bedrock geology (DigRock250) and sea-bed sediments (DigSBS250). Marine Hard Substrate Dataset (DiGHardSubstrate250k) is also made available via this service.
Data from the British Geological Survey's GeoIndex Offshore (cultural data) theme are made available for viewing here. GeoIndex is a website that allows users to search for information about BGS data collections covering the UK and other areas world wide. Access is free, the interface is easy to use, and it has been developed to enable users to check coverage of different types of data and find out some background information about the data. More detailed information can be obtained by further enquiry via the web site: www.bgs.ac.uk/geoindex.
This service provides an Atom feed of datasets that are available for download.
Data from the DiGMap covering the whole of the United Kingdom at a scale of 1:625 000 is available in this OGC WMS service for personal, non-commercial use only. The service is a contribution to the OneGeology-Europe initiative. The layers can be displayed either by age or by lithology. For more information about the digital maps available from the British Geological Survey, please visit http://www.bgs.ac.uk/products/digitalmaps/digmapgb.html.
This national digital GIS product produced by the British Geological Survey indicates the potential for leakage to have a negative effect on ground stability. It is largely derived from the digital geological map and expert knowledge. The GIS dataset contains seven fields. The first field is a summary map that gives an overview of where leakage may affect ground stability. The other six fields indicate the properties of the ground with respect to the extent to which hazards associated with soluble rocks, landslides, compressible ground, collapsible ground, swelling clays and running sands will be increased due to leakage. The data is useful to asset managers in water companies, local authorities and utility companies who would like to understand where. and to what extent, leaking underground pipes or other structures may initate or worsen ground stability.
The data shows superficial polygons, bedrock polygons and fault linear geological information, sourced from published Geological Survey of Northern Ireland 1:250 000 scale maps - superficial (Quaternary 1991) and bedrock (Solid 1997). Full Northern Ireland coverage is available (Bedrock extends west into RI). The data is available in vector format. BGS licensing terms and conditions apply to external use of the data.
This layer of the map based index (GeoIndex) shows the availability of 1:63360 scale geological maps. The maps are available for most of England and Wales and show early geological mapping covering the OS Old Series one inch map sheet areas.
Data identifying landscape areas (shown as polygons) attributed with geological names. The scale of the data is 1:10 000 scale. Onshore coverage is partial with approximately 30% of England, Scotland and Wales available in this version 2 data release. BGS intend to continue developing coverage at this scale; current focus is to include all large priority urban areas, along with road and rail transport corridors. Data are supplied as five themes: bedrock, superficial deposits, mass movement, artificial ground and linear features. 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. The lithostratigraphic scheme arranges rock bodies 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. Superficial deposits are younger geological deposits formed during the most recent geological time; the Quaternary. These deposits rest on older rocks or deposits referred to as bedrock. The superficial deposits theme defines landscape areas (shown as polygons) attributed with a geological name and their deposit type or lithological composition. Mass movement describes areas where deposits have moved down slope under gravity to form landslips. These landslips can affect bedrock, superficial or artificial ground. Mass movement deposits are described in the BGS Rock Classification Scheme Volume 4. However the data also includes foundered strata, where ground has collapsed due to subsidence (this is not described in the Rock Classification Scheme). Caution should be exercised with this data; whilst mass movement events are recorded in this layer, due to the dynamic nature of occurrence significant changes may have occurred since the data was released, as such it should be viewed as a snapshot in time (data should be regarded as at 2008). Artificial (man-made) theme (shown as polygons) indicates areas where the ground surface has been significantly modified by human activity. Whilst artificial ground may not be considered as part of the 'real geology' of bedrock and superficial deposits it does affect them. Artificial ground impacts on the near surface ground conditions which are important to human activities and economic development. Due to the constantly changing nature of land use and re-use/redevelopment, caution must be exercised when using this data as it represents a snapshot in time rather than an evolving picture hence the data may become dated very rapidly. Linear features (shown as polylines) represent geological structural features e.g. faults, folds or landforms e.g. buried channels, glacial drainage channels at the ground or bedrock surface (beneath superficial deposits). Linear features are associated most closely with the bedrock theme either as an intrinsic part of it for example marine bands or affecting it in the case of faults. However landform elements are associated with both bedrock and superficial deposits. All five data themes 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.
An important paper archive of a wide variety of miscellaneous geological information organised on the basis of its location within 1:50 000 scale geological map sheet areas in Great Britain. The majority of the data has been produced or collected by BGS staff since 1835 as part of the mapping programme. The data may not fit into any of the main collections, but is valuable for future projects and answering enquiries.
