The dataset describes the potential of bedrock aquifers across Scotland to sustain various levels of borehole water supply, and the dominant groundwater flow type in each aquifer. There are five aquifer productivity classes: very high, high, moderate, low and very low, and three groundwater flow categories: significant intergranular flow; mixed fracture/intergranular flow; and fracture flow. The dataset is a tool to indicate the location and productivity of bedrock aquifers across Scotland. It may have several uses, including in policy analysis and development; to prioritise aquifer and site investigations; to inform planning decisions; and to improve awareness of groundwater in general. The complexity and heterogeneity of geological formations means that the dataset is only a guide. It is designed to be used at a scale of 1:100,000, and not to assess aquifer conditions at a single point. Latest version: Bedrock aquifer productivity Scotland version 2

Radon is a natural radioactive gas, which enters buildings from the ground. The joint Public Health England (PHE) –British Geological Survey (BGS) digital dataset Radon Potential for Great Britain provides the current definitive map of radon Affected Areas in Great Britain. Exposure to high concentrations increases the risk of lung cancer. PHE (previously known as the Health Protection Agency or HPA) recommends that radon levels should be reduced in homes where the annual average is at or above 200 becquerels per cubic metre (200 Bq m-3). This is termed the Action Level. The PHE defines radon Affected Areas as those with 1% chance or more of a house having a radon concentration at or above the Action Level of 200 Bq m-3. The dataset allows an estimate to be made of the probability that an individual property is at or above the Action Level for radon. This information provides an answer to one of the standard legal enquiries on house purchase in England and Wales, known as CON29 standard Enquiry of Local Authority; 3.13 Radon Gas: Location of the Property in a Radon Affected Area. Radon Potential for Great Britain also provides information on the level of protection required for new buildings as described in the latest Building Research Establishment guidance on radon protective measures for new buildings (Radon: guidance on protective measures for new dwellings; BR 211, 2015 in Scotland, England, Wales and Northern Ireland). This radon potential hazard information for Great Britain is based on PHE indoor radon measurements and BGS digital geology information. This product was derived from BGS Geology 50 (formerly known as DigMap50 V3.14) and PHE in-house radon measurement data. The indoor radon data is used with the agreement of the PHE. Confidentiality of measurement locations is maintained through data management practices. Access to the data is under licence.

Radon is a natural radioactive gas, which enters buildings from the ground. The joint Public Health England (PHE) –British Geological Survey (BGS) digital Indicative Atlas of radon in Great Britain presents an overview of the results of detailed mapping of radon potential, defined as the estimated percentage of homes in an area above the radon Action Level. Exposure to high concentrations increases the risk of lung cancer. PHE (formerly the Health Protection Agency (HPA)) recommends that radon levels should be reduced in homes where the annual average is at or above 200 becquerels per cubic metre (200 Bq m-3). This is termed the Action Level. Public Health England defines radon Affected Areas as those with 1% chance or more of a house having a radon concentration at or above the Action Level of 200 Bq m-3. The Indicative Atlas of radon in Great Britain presents a simplified version of the radon potential for Great Britain with each 1-km grid square being classed according to the highest radon potential found within it, so is indicative rather than definitive. The joint PHE-BGS digital radon potential for Great Britain provides the current definitive map of radon Affected Areas in Great Britain. The Indicative Atlas of radon in Great Britain is published in two documents. The area of England and Wales is published in MILES J.C.H, APPLETON J.D, REES D.M, GREEN B.M.R, ADLAM K.A.M and MYERS, A.H., 2007. Indicative Atlas of Radon in England and Wales. ISBN: 978-0-85951-608-2. 29 pp). The corresponding publication for Scotland is MILES J.C.H, APPLETON J.D, REES D.M, ADLAM K.A.M, GREEN B.M.R, and SCHEIB, C., 2011.

This mineral resource data was produced as part of the Mineral Resource Map of Northern Ireland via a commission from the Northern Ireland Department of the Environment. The work resulted in a series of 21 data layers which were used to generate a series of six digitally generated maps. This work was completed in 2012 with one map for each of the six counties (including county boroughs) of Northern Ireland at a scale of 1:100 000. This data and the accompanying maps are intended to assist strategic decision making in respect of mineral extraction and the protection of important mineral resources against sterilisation. They bring together a wide range of information, much of which is scattered and not always available in a convenient form. The data has been produced by the collation and interpretation of mineral resource data principally held by the Geological Survey of Northern Ireland and was funded via a commission from the Northern Ireland Department of the Environment. These layers display the spatial data of the mineral resources of Northern Ireland. There are a series of layers which consist of: Bedrock: Clay, Bauxitic clay, Coal & Lignite, Coal – lignite proven, Conglomerate, Dolomite, Igneous and meta-igneous rock, Limestone, a 100m buffer layer on the Ulster White Limestone, Meta-sedimentary rocks, Perlite, Salt, Sandstone and Silica Sand. Superficial (unconsolidated recent sediments) : Sand & gravel and Peat. The data except for the salt and proven lignite resource layers was derived from the 1:50 00 and 1:250 000 scale DigMap NI dataset. This version of the data retains the internal geological boundaries which are dissolved out in the accompanying dissolved version. A user guide 'The Mineral Resources of Northern Ireland digital dataset (version 1)' OR/12/039 describing the creation and use of the data is available.

This dataset has now been superseded, please see the Estimated Urban Soil Chemistry dataset. There are two themes to BGS urban soil chemistry, the point source dataset and the estimated dataset. The point source urban soil chemistry data comprises the locations and concentrations (mg kg-1) of Arsenic (As). Cadmium (Cd), Chromium (Cr), Nickel (Ni) and Lead (Pb) in urban topsoil samples. The Estimated Urban Soil Chemistry data indicates the estimated geometric mean concentrations (mg kg-1) of As, Cd, Cr, Ni and Pb in topsoil derived by spatial interpolation of the Point Source Urban Soil Chemistry data. Both urban soil chemistry datasets are derived from high resolution urban soil geochemical data from the BGS Geochemical Baseline Survey of the Environment (G-BASE) project. The Urban Soil Chemistry data can be used to assist Local Planning Authorities to identify those areas where a risk assessment may need to be carried out by developers. Comparison of this spatially referenced geochemical data with information on current or historic land use and geological information might help environmental professionals decide whether high PHE concentrations in topsoils can be attributed to geogenic or anthropogenic sources. The dataset is based on, and limited to, an interpretation of the records in the possession of the BGS at the time the dataset was created.

This national dataset brings together sixteen national datasets to create a GIS product that provides the information necessary to determine the extent to which the ground is suitable for infiltration sustainable drainage systems (SuDS). It includes derivations of the following datasets: soluble rocks, landslide hazards, groundwater flooding susceptibility, made ground, shallow mining hazards, geological indicators of flooding, depth to water table, superficial thickness, compressible ground, collapsible ground, swelling clays, running sands, predominant flow mechanism, permeability indices and the Environment Agencys source protection zone dataset. All datasets have been reclassified and reattributed (with text descriptions and a score field indicating the suitability of the ground for infiltration) and feature in the end product both as single entities, but also in derived 'screening' maps that combine numerous datasets.

The London Earth data is part of a nationwide project to determine the distribution of chemical elements in the surface environment, namely Geochemical Baseline Survey of the Environment (G-BASE). London Earth focuses on the soil of the capital city, the limits of the survey being defined by the Greater London Authority (GLA) administrative boundary. Chemical elements have been determined by X-ray fluorescence spectrometry (XRFS) at the laboratories of the British Geological Survey (BGS) in Keyworth, Nottingham. These results are presented as a MS Excel file.

The BGS 3D scans store holds digital 3-dimensional scans of BGS palaeontological and petrological specimens. The data include 3-dimensional meshes and 2-dimensional images exported by the scanning hardware and software. Data are stored in software-independent 3D modelling formats such as .OBJ and .PLY. These scans are useful for research purposes, for example allowing members of the broader geoscience community to interactively view a particular specimen, and for publicising BGS specimen holdings.

Data identifying landscape areas (shown as polygons) attributed with geological names and rock type descriptions. The scale of the data is 1:10 000 scale providing bedrock geology. 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. 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 7500 million years ago, to the relatively young Pliocene, 58 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.
