The BGS Predictive Seabed Sediments UK v1 dataset includes digital maps of seabed sediment (SBS) composition across the UK Continental Shelf (UKCS). The dataset includes one classified SBS map (Folk sediment class; vector), and three percentage-sediment maps (rasters) giving the proportions of gravel, sand, and mud. The dataset is generated using a machine learning algorithm known as a Distributional Random Forest (DRF). The model uses input data to predictively classify what seabed sediments are most likely to be the dominant sediment present. It does so, using more than 38,000 seabed sediment samples (collated from various sources) with measurements of the proportion of mud, sand and gravel from locations across the study area. The predictions are constrained against covariate variables that are known to influence which sediment is most likely to occur. These include bathymetry data morphometric derivatives (at multiple spatial scales), as well as hydrodynamic data layers (currents and tidal). The dataset was reviewed via a qualitative assessment (QA) protocol by subject-area experts (e.g. contrasting with previous mapping, and local examples of higher-resolution data and mapping), and following methodological improvements based on this feedback, updated SBS map products were prepared. The dataset is presented at a national-scale, with a spatial resolution of approximately 110m, covering the UKCS (slightly modified UKCS area based on data availability).

Data identifies landscape areas (shown as polygons) attributed with type of artificial or man-made ground. It indicates areas where the ground surface has been significantly modified by human activity. The data is presented at 1:50 000 scale. Onshore coverage is provided for England, Scotland, Wales and the Isle of Man. Approximately 99% coverage is available and BGS is committed to completing the coverage, and ongoing updates as part of its ongoing national survey. Types of artificial ground include: Disturbed ground areas of ill-defined shallow or near surface mineral workings where distinction cannot be made between made and worked ground. Infilled ground areas where original geology has been removed and then wholly or partially back filled includes waste or landfill sites. Landscaped ground areas where surface has been reshaped includes former sand and gravel workings for recreation and amenity use. Made ground man made features including embankments and spoil heaps. Reclaimed ground are areas of land fill, where new ground is created, usually in coastal margins, may be for example a consequence of draining of submerged wetlands and beach rebuilding. Worked ground areas where ground has been removed including quarries and road cuttings. 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. 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.

The BGS Seabed Geology 10k: Bristol Channel v.2 digital map provides detailed and accurate characterisation of the seabed geology, based on seabed and shallow-subsurface data. This dataset incorporates three complementary map components (Substrate Geology, Structural Geology, and Geomorphology) presented at 1:10 000 scale, provided as discrete layers for viewing within a Geographic Information System (GIS). The bedrock geology is divided into 23 stratigraphical units: Aber Mawr Shale Formation (ABM); Avon Group (AVO); Bridport Sand Formation (BDS); Bishopston Mudstone Formation (BISHM); Charmouth Mudstone Formation (CHAM); Carboniferous Limestone Supergroup (CL); Devonian And Carboniferous Rocks (Undifferentiated) (DEVC); Devonian Rocks (Undifferentiated) (DEV); Dyrham Formation And Beacon Limestone Formation (Undifferentiated) (DYBN); Hangman Sandstone Formation (HASA); Inferior Oolite Group (INO); Lias Group (LI); Ludlow Rocks (Undifferentiated) (LUDL); Lavernock Shale Member (LVN); Milford Haven Subgroup (MIH); Mercia Mudstone Group (MMG); Pembroke Limestone Group (PEMB); Penarth Group (PNG); Porthkerry Member (PO); Skrinkle Sandstones Subgroup (SES); St Mary's Well Bay Member (STM); South Wales Lower Coal Measures Group (SWLCM); Triassic Rocks (Undifferentiated) (TRIA). The Lexicon code of the stratigraphical units is provided in parentheses, as defined in the ‘BGS Lexicon of Named Rock Units’. The superficial deposits mapped are comprised of only marine sediments (Marine Deposits Undifferentiated (MDU)) that were classified based on their grain size. The sediments are divided into Gravel (V): Sand (S); Mud (M); Sand and Gravel (XSV); Sand and Mud (XSM); and Gravel, Sand and Mud (XVSM). The RCS code of the stratigraphical units is provided in parentheses, as defined in the ‘BGS Rock Classification Scheme’.

Data identifying landscape areas (shown as polygons) attributed with geological descriptions and thermal properties of geological materials. The scale of the data is 1:250 000 scale for the Thermal Properties V1 dataset. Onshore coverage is for Great Britain and the Isle of Man. This dataset shows thermal properties relating to bedrock beneath our feet. The information can be used to assess the potential for closed and open loop ground source heat pumps across, or deeper geothermal assessments, across the United Kingdom. The attribution and spatial data underpinning the model are that which is described and shown by Rollin (1987) and Gale (2004, 2005). The information is presented vector-based, irregular polygon coverage at 1:250 000 scale Each polygon is attributed with a range of geological properties including modelled values for Thermal conductivity, thermal diffusivity, specific heat capacity and density. 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.

Data identifying landscape areas (shown as polygons) attributed with geological names and rock type descriptions. The data is presented at 1:50 000 scale. Onshore coverage is provided for England, Scotland, Wales and the Isle of Man. Approximately 99% coverage is available and BGS is committed to completing the coverage, and ongoing updates as part of its ongoing national survey. Superficial deposits are the youngest geological deposits formed during the most recent period of geological time, the Quaternary, which extends back about 2.58 million years from the present. They lie on top of older deposits or rocks referred to as bedrock. Superficial deposits were laid down by various natural processes such as action by ice, water, wind, and weathering. As such, the deposits are denoted by their BGS lexicon name, which classifies them the basis of their mode of origin (lithogenesis) with names such as, 'glacial deposits', 'river terrace deposits' or 'blown sand'; or the basis of their composition such as 'peat'. Most of these superficial deposits are unconsolidated sediments such as gravel, sand, silt, and clay. The digital data includes attribution to identify each deposit type (in varying levels of detail) as described in the BGS Rock Classification Scheme (volume 4). 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.

The BGS Geology 50k datasets are a digital representation of the geological maps of Great Britain at 1:50 000 scale. The data is presented at 1:50 000 scale. Onshore coverage is provided for England, Scotland, Wales and the Isle of Man. Approximately 99% coverage is available and BGS is committed to completing the coverage, and ongoing updates as part of its national survey activities. BGS Geology 50k V9 dataset includes 4 geological themes: bedrock, superficial deposits, mass movement and artificial ground. An additional map component detailing Linear features is also provided. The Bedrock theme 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 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. The Superficial theme describes the youngest geological deposits formed during the Quaternary period. They lie on top of older deposits or rocks referred to as bedrock. Superficial deposits were laid down by various natural processes and as such, the deposits are denoted by their BGS lexicon name, which classifies them based on mode of origin (lithogenesis) i.e., 'glacial deposits', 'river terrace deposits' or based on their composition i.e., 'peat'. Most are unconsolidated sediments. The Mass movement theme 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 (the time frame being defined by the date of survey, not the date of digital map publication). The Artificial theme describes 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. 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 (the time frame being defined by the date of survey, not the date of digital map publication). The Linear map layer describes linear features that are associated most closely with the bedrock theme, either as an intrinsic part of it (for example, depiction of marine bands) or affecting it (for example depiction of faults between bedrock object). However, landform elements are associated with both bedrock and superficial deposits. The linear features are organised into seven main categories i.e., Alteration Area”, “Bedrock”, “Faults”, “Fold Axis”, “Fossil Horizon”, “Landform”, and “Mineral Vein”, some having additional applicable attribution, for example a LEX-RCS code, or a fault name. All 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.

The BGS BritPits v3 is derived from a BGS database, which contains records of mineral workings covering the Great Britain, Northern Ireland, Isle of Man and Channel Islands. The coverage includes active, inactive, dormant and ceased sites and a range of mineral operations, including mines, quarries, onshore oil and gas fields, together with wharfs and rail depots handling mineral products and industrial processes which produce a mineral product. The information on currently active sites is continually updated with the cooperation of both local authorities and the minerals industry.

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. The bedrock geology of Great Britain is very diverse and includes three broad classes based on their mode of origin: igneous, metamorphic, and sedimentary. The data includes attribution to identify each rock type (in varying levels of detail) as described in the BGS Rock Classification Scheme (volumes 1-3). The bedrock has formed over long periods of geological time, from the Archean eon some 4000 million years ago, to the relatively young Pliocene, 5.33 million years ago. The age of the rocks is identified in the data through their BGS lexicon name (published for each deposit at the time of the original survey or subsequent digital data creation). For stratified rocks i.e., arranged in sequence, this will usually be of a lithostratigraphic type. Other rock types for example intrusive igneous bodies will be of a lithodemic type. More information on the formal naming of UK rocks is available in the BGS Lexicon of Named Rock Units. 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. 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.
