The HiRES-1 project acquired airborne geophysical data during 1998. Coverage included the Central Midlands of England and into the associated Welsh Borderland. Survey flying for the collaborative BGS and World Geoscience Corporation Ltd (WGC) high resolution geophysical and environmental survey was completed in early September 1998. The data comprise multi-channel gamma ray spectrometer, magnetometer and dual frequency VLF-EM. Flight line spacing was 400 m with tie lines at 1200 m and the total area surveyed is some 14 000 km2. Flight-line orientations are W–E over the western survey area, SW–NE over the eastern area. Ground clearance was maintained at 90 m in rural areas, increasing to about 240 m in built-up zones. The project and data descriptions are provided in an internal BGS report: R J Peart, R J Cuss, D Beamish and D G Jones, 2003.

The joint PHE-GSNI-BGS digital Radon Potential Dataset for Northern Ireland provides the current definitive map of radon Affected Areas in Northern Ireland. The Radon Potential map for Northern Ireland shows the estimated percentage of homes in an area exceeding the radon Action Level. This is the basic information to assigning the level of protection required for new buildings and extensions, as described in the Building Research Establishment guidance BR-413 Radon: Guidance on protective measures for new dwellings in Northern Ireland (2004). The Radon Potential map for Northern Ireland is based on PHE indoor radon measurements and 1:10 000 or 1: 250 000 scale digital geology information provided by the Geological Survey of Northern Ireland (GSNI). The indoor radon data is used with the agreement of the Northern Ireland Environment Agency and PHE. Confidentiality of measurement locations is maintained through data management practices. Access to the data is restricted. 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 Action Level. 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. Further information on radon can be obtained from www.ukradon.org
Scanned collection of seismological journals and offprints. The original collection was compiled by John Wartnaby. John Wartnaby was a curator at the Science Museum, London, and wrote a historical survey of seismology and scientific instruments. His accumulated papers consist chiefly of offprints and articles, and many older British Association seismological reports. The collection is part of the National Seismological Archive.

This dataset is a characterisation of discontinuity types found within rocks and soils in Great Britain. Discontinuities are breaks, fractures or planes of weakness in the rock mass. The dataset includes type, frequency and orientation of discontinuities within rock and soil materials at formation (local to regional) scale. The discontinuities are classified in 3 categories: stratification (bedding planes), foliation (mineral banding) and rock mass description. The dataset aims to facilitate the preliminary research for planning and design of buildings, infrastructure and resource extraction. It forms part of the DiGMap Plus dataset series of GIS layers which describes the engineering properties of materials from the base of pedological soil down to c. 3m depth (ie the uppermost c.2m of geology). These deposits display a variable degree of weathering, but still exhibit core engineering characteristics relating to their lithologies.
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.

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.
Offprints of articles relating to Geomagnetism from 1822 to 1981. Offprints collected by Kew Observatory, Meteorological Office, Edinburgh and Greenwich Observatory (Herstmonceux castle). The first page of each offprint has been digitised to produce a finding aid.
Underground extraction of minerals and rocks has taken place in Great Britain for more than 5000 years. The dataset draws together a range of diverse information; the geology, the primary constraint on distribution; additional information sourced from published literature and knowledge from BGS experts. Areas of known underground mining are identified with an indication of the level of hazard associated for each site. The presence of former underground workings, particularly where shallow, may collapse, causing surface settlement or subsidence. The type of material mined, age and extent of working (where known) is used to assess and classify the hazard at each site. The value is based on an A (mining is not known to have occurred) to E (evidence of extensive underground mining is known) scale. Mining Hazard (not including coal) covers areas of known underground working in Great Britain. The coverage is not comprehensive as areas with no evidence of underground working are not included in the data. The dataset was created to provide a comprehensive overview of Great Britain's long and complicated mining legacy. It provides essential information for planners and developers working in areas where former underground mine workings may have occurred. Also for anyone involved in the ownership or management of property, including developers, householders and local government.
