  • All data dictionaries held in Oracle. They include both administrative (e.g. codes for companies), scientific (e.g. codes for deformation episodes) and geographic (e.g. codes for countries). Typically, they are used to constrain the allowable values held in other Oracle datasets. In some cases they are an implementation of the classifications that the BGS uses in its work.

  • The GeoSure data sets and reports from the British Geological Survey provide information about potential ground movement or subsidence in a helpful and user-friendly format. The reports can help inform planning decisions and indicate causes of subsidence. The methodology is based on BGS DiGMap (Digital Map) and expert knowledge of the behaviour of the formations so defined. This dataset provides an assessment of the potential for a geological deposit to shrink and swell. Many soils contain clay minerals that absorb water when wet (making them swell), and lose water as they dry (making them shrink). This shrink-swell behaviour is controlled by the type and amount of clay in the soil, and by seasonal changes in the soil moisture content (related to rainfall and local drainage). The rock formations most susceptible to shrink-swell behaviour are found mainly in the south-east of Britain. Clay rocks elsewhere in the country are older and have been hardened by burial deep in the earth and are less able to absorb water. The BGS has carried out detailed geotechnical and mineralogical investigations into rock types known to shrink, and are modelling their properties across the near surface. This research underpins guidance contained in the national GeoSure dataset, and is the basis for our responses to local authorities, companies and members of the public who require specific information on the hazard in their areas. The BGS is undertaking a wide-ranging research programme to investigate this phenomenon by identifying those areas most at risk and developing sustainable management solutions. Complete Great Britain national coverage is available. The storage formats of the data are ESRI and MapInfo but other formats can be supplied.

  • BGS holds a disaster recovery copy of the microfiche of the statutory mine abandonment plans for the Coal Authority. This collection is an incomplete copy of the mine plans deposited with the Coal Authority and held on behalf of the Health and Safety Executive under statutory legislation. Not for public use.

  • The map shows the localities where samples that form part of the BGS rock collections have been taken. Many of these samples are from surface exposure, and were collected by BGS geologists during the course of geological mapping programmes. Others are from onshore boreholes or from mine and quarry workings. The principal collections are the E (England and Wales), S (Scotland), N (continuation of the S collection) and the MR (miscellaneous). The collections, which are held at the BGS offices at Keyworth (Nottingham) and Edinburgh, comprise both hand specimens and thin sections, although in individual samples either may not be immediately available. Users may also note that the BGS holds major collections of borehole cores and hand specimens as well as over a million palaeontological samples. The Britrocks database provides an index to these collections. With over 120,000 records, it now holds data for some 70% of the entire collections, including the UK samples shown in this application as well as rocks from overseas locations and reference minerals. The collections are continuously being added to and sample records from archived registers are also being copied into the electronic database. Map coverage is thin in some areas where copying from original paper registers has not been completed. Further information on Britrocks samples in these and other areas can be obtained from the Chief Curator at the BGS Keyworth (Nottingham) office or from the rock curator at the BGS Murchison House (Edinburgh) office.

  • 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 SEA portal is managed by the BGS on behalf of DECC and provides free access to downloadable data, information and reports which have been produced through the SEA process. The Department of Trade and Industry (now DECC) began a sequence of sectoral SEAs of the implications of further licensing of the UK Continental Shelf (UKCS) for oil and gas exploration and production in 1999. The SEA Process subdivided the UKCS into eight areas shown; beginning in 2008, integrated Offshore Energy SEAs have been undertaken that cover the whole UKCS. An integral part of the SEA programme has been a series of research and monitoring surveys commissioned to acquire new data about the offshore environment and used to help inform the relevant SEAs. Many files can be downloaded directly from portal. Those that are too large to download can be ordered via the website for postal delivery from BGS.

  • The joint PHE-GSNI-BGS digital Indicative Atlas of Radon in Northern Ireland 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. The Indicative Atlas of Radon in Northern Ireland presents a simplified version of the Radon Potential Dataset for Northern Ireland, with each 1-km grid square being classed according to the highest radon potential found within it, so is indicative rather than definitive. The Radon Potential Dataset for Northern Ireland provides the current definitive map of radon Affected Areas in Northern Ireland. The Indicative Atlas of Radon in Northern Ireland is published in Z Daraktchieva, J D Appleton, D M Rees, K A M Adlam, A H Myers, S A Hodgson, N P McColl, G R Wasson and L J Peake, 2015. Indicative Atlas of Radon in Northern Ireland. PHE-CRCE-017, 22 pp. Radon is a natural radioactive gas, which enters buildings from the ground. Exposure to high concentrations increases the risk of lung cancer. Public Health England (PHE) recommends that radon levels should be reduced in homes where the annual average exceed 200 becquerels per cubic metre (200 Bq m-3), the radon Action Level. Public Health England defines radon Affected Areas as those with 1% chance or more of a house having a radon concentration exceeding the Action Level.

  • The BGS groundwater levels dataset is a gridded interpolation of depth to groundwater. The dataset is a raster grid, with 50 × 50 metre pixels holding values that represent the probable maximum depth, in metres, to the phreatic water table. This represents the likely lowest water level, under natural conditions, in an open well or borehole drilled into the uppermost parts of a rock unit. The dataset has been modelled from topography and hydrology, assuming that surface water and groundwater are hydraulically connected. It has not used observations of groundwater level in wells or boreholes directly, but they have been used to validate its performance.

  • These are the results obtained from an empirical test looking at the communicative effectiveness between two types of two dimensional (2D) map formats (Choropleth maps, and Cartograms) of the Greater London area of the United Kingdom. Participants were interviewed and observed individually during the procedure. The results contain the recorded measurements of spatial accuracy, and the time taken for each participant to answers 3 test questions. A post-test qualitative reaction of each participants' preference between the two map types is recorded, along with their gender, age, visual impediments, and self-assessed map reading ability.

  • The dataset consists of data for the UK for the Sustainable Development Goal 6.6.1: groundwater sub-indicator for the period 1990 to 2019. The dataset reports for the UK against Sub-Indicator 5 of Goal 6.6.1, following the recommended procedures in the UNEP report on monitoring methodologies for that sub-indicator. The sub-indicator is defined as the change in mean groundwater levels, averaged over a five-year period, from a mean in levels over a previous five-year reference period. Groundwater level data was obtained from BGS’ WellMaster database. 192 groundwater level monitoring stations were processed and, following quality control, 154 were used to provide estimates of regional variation in groundwater levels for 19 of the 34 HydroBASINS at Level 6 in Great Britain and Northern Ireland. As required by the guidance in the monitoring methodology, the sites chosen are representative of local and regional groundwater systems and are observation and monitoring boreholes where groundwater levels are not systematically affected by abstraction. All sites chosen have average monitoring frequencies of greater than one observation a month. The dataset is provided as a .csv file with the following headers: Column A: HYBAS_ID, HydroBASIN unique identification number. Column B: reference period (1990 to 1994). Columns C to AA: reporting periods (five-year periods starting in 1991) with data reported as percentage change (relative to reference period) in running mean five-year groundwater level by HydroBasin.
