The data comprises information on the subsurface structure of stratigraphic levels and units in the United Kingdom, detailing depth to and thickness of the units. These result from projects in different parts of the UK performed at different times. Common working scales are 1:50 000 and 1:250 000 with appropriate differences in detail. Much mapping results from interpretation of seismic data, and as a result many of the structural maps are in time rather than depth, although some have been depth converted.

GeoScholar is a set of free geological data - available in GIS format - for UK universities and the higher education sector, to support teaching and learning within the geosciences. The dataset includes digital geological map data from BGS, aerial photos from Infoterra, NEXTmap digital terrain model from Intermap Technologies, borehole data and their corresponding logs, several BGS geological map sheets. Each Geoscholar teaching package will include 12 different geographical regions, including Assynt, Coniston and South West Wales.

The dataset is based on a 1 hectare(ha) vector grid which covers the whole of Scotland. It has been populated with a series of environmental and cultural assets, reflecting the presence or absence of an asset in an individual cell. The dataset has been designed to enable a single asset to be displayed in a generalised fomat; total numbers of assets within a given cell; or the opportunity to create in unique combination of the assets based on the generalised 1 ha data. The data is also available at 1km.

The 5km Hex GS Running Sand dataset shows a generalised view of the GeoSure Running Sand v7 dataset to a hexagonal grid resolution of 64.95km coverage area (side length of 5km). This dataset indicates areas of potential ground movement in a helpful and user-friendly format. The rating is based on a highest level of susceptibility identified within that Hex area: Low (1), Moderate (2), Significant (3). Areas of localised significant rating are also indicated. The summarising process via spatial statistics at this scale may lead to under or over estimation of the extent of a hazard. The supporting GeoSure reports can help inform planning decisions and indicate causes of subsidence. The Running Sand methodology is based on the BGS Digital Map (DiGMapGB-50) and expert knowledge of the behaviour of the formations so defined. This dataset provides an assessment of the potential for a geological deposit to show running sand behaviour under the action of flowing water, a characteristic usually of saturated sand and silt grade material. Complete Great Britain national coverage is available.

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.

The property subsidence assessment dataset provides an understanding of the shrink-swell hazard at both the individual property and/or postcode level for England and Wales. It builds upon the BGS GeoSure shrink-swell data by mapping the hazard to the individual building polygon and considering the other susceptibility factors of building type, foundation depth, and drainage and tree proximity. The data consist of GIS building polygons with an overall susceptibility to subsidence score between 1-100. Scores are also classified from non-plastic to very high. Each building polygon is also scored from 1-10 for each subsidence factor (geology, foundation, drainage, building type, building storey and tree proximity). Postcode data is also available as a table showing the ‘average’ PSA score for all buildings within the postcode. The identification of shrink-swell related subsidence prone areas, alongside the inclusion of potential sources to exacerbate these phenomena, can better inform insurers and homeowners and form the basis to make decisions concerning prevention and remediation. The product enhances geological information obtained from GIP (BGS GeoSure Insurance Product) and GeoSure via the inclusion of the crucial shrink-swell susceptibility factors (proximity to trees and foundation depth). This therefore allows the derivation of a risk element for the housing stock at Building level, which is then generalised to Postcode level.

The database contains basic tabulated field data resulting from the work of the BGS East Grampians Project in the early 1980s to mid 1990s. Records include the locations of stations at which field observations were made, structural measurements and sample locations. To this end, the database provides an index to locations and structural data. However, it needs to be stated clearly that labels given to structural elements are largely subjective beyond the identification of bedding. This means that the structural data are largely unusable without a clear understanding of their context and with regard to the primary paper record on which descriptions of the observed structures are recorded. The data are held in MS ACCESS tables which are related via the Station number as the primary key. The coverage is mainly confined to the North East Grampian Highlands of Scotland. The database is currently unused and has not been added to since the end of the East Grampians Project. The station location and structural data are effectively complete. However, fields in the sample database, such as the sample stratigraphy, are largely incomplete because, at the time the data were acquired, the stratigraphy at each station was formally undefined. The most effective way of presenting and investigating the data is via GIS.
