This data set contains land cover/land use data for the year 1990 and 2015 obtained through processing of Landsat images of US Geological Survey. These data sets were obtained through a supervised classification carried out with Landsat 8 image for 2015; Landsat 4 and 5 were used for land use classification of 1990.

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.
The Single Onshore Borehole Index (SOBI) is an index of over 1 million boreholes, shafts and wells and references collections of digital and analogue records from all forms of drilling and site investigation work held by the BGS. The index covers onshore and near shore boreholes from Great Britain dating back to at least 1790 and ranging from one to several thousand metres deep. Some 50,000 new boreholes are added each year. The majority of the records contain written descriptions of the ground encountered. The SOBI index database originated in 1988 from a number of existing tables and from data input from a variety of coding forms. Therefore not all fields in the database are populated and data that should be in some fields may currently form part of the entries in another. The index is available on the BGS website via the Geoindex
This is the core collection of photographs in BGS it represents photographs taken by professional photographers and selected by subject and quality for public reference in the BGS libraries. The collection dates from c 1890 to c.1995 and is organized in a series of sub-collections depending on which office the photographers were based. The collection covers photography taken in the field during the geological mapping programme. Series A, the main Land Survey collection for England and Wales, are all taken by professional photographers and are of high quality. Dates from c.1890 to the start of the current "P" system, the first 7500 are glass plates. Series B, Edinburgh, part of the main Land Survey collection for Scotland, full plate size and all glass plates. Series C, Edinburgh, part of the main Land Survey collection for Scotland, half plate size. Series D, Edinburgh, part of the main Land Survey collection for Scotland consists of large format negative size with additional 35mm transparencies, earlier parts of the collection are black and white, later, colour. Series L, Keyworth, the main Land Survey collection for Northern England and Wales emanating from the Leeds Office, all are taken by professional photographers and include large format black and white, colour originals and colour 35 mm transparencies. Access constraints are only physical constraints relating to handling negatives and glass plates. scans are available in the Geoscience Imagebase. Photographs are either: Out of copyright; Crown or NERC.
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 slope instability. Landslide hazard occurs due to particular slope characteristics (such as geology, gradient, sources of water, drainage, man-made constructions) combining to cause the slope to become unstable. Downslope movement of materials, such as a landslide or rockfall may lead to a loss of support and damage to buildings. Complete Great Britain national coverage is available. The storage formats of the data are ESRI and MapInfo but other formats can be supplied.
The IGRF is a global model of the geomagnetic field. It allows spot values of the geomagnetic field vector to be calculated anywhere from the Earth's core out into space. The IGRF is generally revised every five years by a group of modellers associated with the International Association of Geomagnetism and Aeronomy (IAGA).
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.
Miscellaneous geological records for Scotland and Northern England of current or semi-current interest filed in order of accession. Some 65 accessions held which will be subject to review for permanent retention/destruction. Dataset created c.1970 and Indexed on Land Survey Record Index Database.
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 Quaternary deposits summary lithologies dataset is a digital geological map across the bulk of the UK Continental Shelf (UKCS), for areas up to a water depth of 200 m, which groups the deposits into classes based on similar engineering geology characteristics. The map is derived from (unpublished) BGS 1:1,000,000 scale Quaternary digital geological mapping, so is effective at that scale. The map was produced in 2014 in collaboration with, and co-funded by, The Crown Estate as part of a wider commissioned project to assess seabed geological constraints on engineering infrastructure across the UKCS. The data are held by the BGS as an ESRI ArcGIS Shapefile The divisions on the map combine the Quaternary deposits into 7 categories of similar strength and lithological variability, each with a ‘Category’ title that summarises their main lithological character: diamict; firm to hard interbedded (layered); firm to hard mud; sand and gravel; soft interbedded; soft mud; undifferentiated. These categories can be used as a basis for assessing, in conjunction with a range of other geological factors, the geological constraints on engineering structures at or close to the seabed.
