  • Digitised versions of a set of 1:100,000 scale maps of aquifer vulnerability for England and Wales. The dataset identifies the vulnerability to pollution of major and minor aquifers as defined by the Environment Agency, utilising a combination of geological, hydrogeological and soils data. The maps are designed to be used by planners, developers, consultants and regulatory bodies to ensure that developments conform to the Policy and Practice of the Environment Agency for the protection of Groundwater. Please note that these maps are based on data from the late 1980's and early 1990's, more up-to-date digital data may now be available from the Environment Agency. Flat maps may be purchased from the BGS, some sheets are now out of print.

  • These maps provide an overview, at the national scale, of the spatial relationships between principal aquifers and some of the major shale and clay units in England and Wales. The data comprises a series of occurrence maps shows the distribution of rock units that form the principal aquifers and some major shale and clay units in England and Wales. In addition, a series of separation maps show the vertical separation between pairs of shales or clays and overlying aquifers. If shale gas resources are to be developed in the UK, the implications for groundwater will need to be considered as part of any risk assessment. A step in such an assessment will be to understand and quantify the spatial relationships between the potential shale gas source rocks (including both shales and some clay units) and overlying aquifers. The datasets used to produce the aquifer maps, the shale and clay occurrence maps and the separation maps are available to download for your own use. As with other BGS data sets available for download, this will enable you to work offline to develop your own systems and methodologies using BGS data. The data used to produce the aquifer, shale and clay maps are available below as ESRI GIS and KML files.

  • 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 layer of the GeoIndex shows the localities for which details of identified fossil specimens in the BGS Biostratigraphy Museum are databased. Only Ordovician and Silurian specimens listed currently. Samples and taxonomic identifications will be listed and will in future be able to be queried using the query-by-attribute tool to the right of the map. See also Fossil Localities. Material is available for inspection on application by e-mail; it is free for academic research but is charged for commercial work. Specimens are sometimes available for loan to bona fide academics.

  • The map shows the localities of significant fossil samples, either collected by BGS Staff, or donated by individuals and institutions. The BGS fossil collections contain over 2 million specimens, including a sizeable quantity of type, figured and cited material. Since a small number of fossil locations are confidential, you are unable to view this dataset at large scales. However, if you send a data enquiry, such information may be made available. Enquiries are normally free, but a charge may be levied depending upon the time taken; users will be notified in advance. Material is available for inspection on application by e-mail. Specimens are sometimes available for loan to bona fide academics.

  • The dataset describes the potential of superficial deposit aquifers across Scotland to sustain various levels of borehole water supply, based on four productivity classes: high; moderate to high; moderate; and a category to signify that a deposit is 'not a significant aquifer'. All superficial deposits aquifers in Scotland are assumed to have primarily intergranular groundwater flow. The dataset is a tool to indicate the location and productivity of superficial deposit 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.

  • This dataset for the UK, Jersey and Guernsey contains the Corine Land Cover (CLC) changes between 2006 and 2012. This shapefile has been created by combining the land cover change layers from the individual CLC database files for the UK, Jersey and Guernsey. CLC is a dataset produced within the frame of the Initial Operations of the Copernicus programme (the European Earth monitoring programme previously known as GMES) on land monitoring. CLC provides consistent information on land cover and land cover changes across Europe. This inventory was initiated in 1985 (initial reference year 1990) and then established a time series of land cover information with updates in 2000 and 2006 with the last one being for the 2012 reference year. CLC products are based on the analysis of satellite images by national teams of participating countries - the EEA member and cooperating countries - following a standard methodology and nomenclature with the following base parameters: - 44 classes in the hierarchical three level Corine nomenclature - Minimum mapping unit (MMU) for Land Cover Changes (LCC) for the change layers is 5 hectares. The resulting national land cover inventories are further integrated into a seamless land cover map of Europe. Land cover and land use (LCLU) information is important not only for land change research, but also more broadly for the monitoring of environmental change, policy support, the creation of environmental indicators and reporting. CLC datasets provide important information supporting the implementation of key priority areas of the Environment Action Programmes of the European Union as protecting ecosystems, halting the loss of biological diversity, tracking the impacts of climate change, assessing developments in agriculture and implementing the EU Water Framework Directive, among others.

  • Coal resource maps for the whole of the UK have been produced by the British Geological Survey as a result of joint work with Department of Trade and Industry and the Coal Authority. The Coal Resources Map is a Map of Britain depicting the spatial extent of the principal coal resources. The map shows the areas where coal and lignite are present at the surface and also where coal is buried at depth beneath younger rocks. The maps are intended to be used for resource development, energy policy, strategic planning, land-use planning, the indication of hazard in mined areas, environment assessment and as a teaching aid. In addition to a general map of coal resources for Britain data also exists for the six inset maps: Scotland; North-East; North-West; East Pennines; Lancashire, North Wales and the West Midlands; South Wales, Forest of Dean and Bristol. Available as a paper map, flat or folded, from BGS Sales or as a pdf on a CD if requested.

  • 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.

  • The original version of this dataset contained lithologies interpreted as representing a mineral resource for mineral extraction. Collated on a County by County basis as part of the former Office of the Deputy Prime Minister (ODPM) Mineral Resource Information in support of National Regional and Local Planning between 1994 and 2006. A primary objective is to produce baseline data in a consistent format that can be updated, revised and customised to suit planning needs, including Mineral Local Plans and Regional Planning Guidance, as well as those of industry. The BGS Mineral Resource data does not determine mineral reserves and therefore does not denote potential areas of extraction. Only onshore, mainland mineral resources are included in the dataset. This dataset has been produced by the collation and interpretation of mineral resource data principally held by the British Geological Survey. The mineral resource data presented are based on the best available information, but are not comprehensive and their quality is variable. The dataset should only be used to show a broad distribution of those mineral resources which may be of current or potential economic interest. The data should not be used to determine individual planning applications or in taking decisions on the acquisition or use of a particular piece of land, although they may give useful background information which sets a specific proposal in context. During 2011-2012 revisions were made to areas of the resource linework. These changes were made as a result of new research and release of a new version of DiGMap (v5). This work was on an ad hoc basis but affects all resource layers. The paper maps were not re-released with this data update.
