The database contains images of the UK, recorded from various airborne multispectral sensors operated by or on behalf of the NERC airborne remote sensing facility. It includes data from the ATM, CASI, PMI, and thermal line scanner instruments. The data are stored in proprietary formats on various types of magnetic media. Full datasets belong to the NERC but BGS has access, the NERC earth observation data centre, NEODC, hold the data. For all enquiries contact NEODC at http://www.neodc.rl.ac.uk.

High Resolution, Airborne Magnetic, Radiometric, VLF Survey over north Midlands of GB. 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.

Data from geophysical surveys in many African countries carried out by the British Geological Survey for different agencies. The surveys range from regional gravity and airborne magnetic mapping to targetted surveys for mineral and water. Individual surveys do not yet have metadata entries: this entry describes a notional database that represents all geophysical surveys carried out within the region.

Analogue aeromagnetic surveys of Great Britain for the Geological Survey (GSGB), subsequently digitised. Commercial Analogue survey of North Sea by Aerosurveys Inc, subsequently digitised by BGS. Commercial digital (+ one analogue) surveys off NW/N/NE of Britain by Huntings Geology and Geophysics and ESL, purchased outright by BGS. Local surveys, digital and analogue aeromagnetic (+ other methods) surveys for BGS and commercial companies. Data acquired over many years by different companies. Surveys vary from High Resolution helicopter covering a few square kms to regional surveys covering 1000s of square kms. Some data recorded analogue, subsequently digitised, other data full digital capture with GPS navigation. Approximately 75% of the bounding rectangle covered. Flight line separation varies between 2km and 0.4km, line spacing typically 2km over UK but 0.4km over Devon/Cornwall. Flight line separation for Aerosurveys/Huntings surveys vary between 6.4 to 15 km. Detailed surveys at various resolutions. Along line spacing varies, analogue data: digitised from 1:63 360 and 1:253 440 scale map sheets and digital surveys: Decca navigation, 305m asl (above sea level). Local helicopter surveys, analogue and digital recordings, various survey heights. HiRES survey, full digital data capture at 0.1 sec intervals, GPS navigation, 90m survey height.

The BGS database of geological maps is an index into BGS holdings of modern and historical published geological maps, geological standards and field slips, and also contains a range of other map series, including geophysical maps, geochemical maps, hydrogeological maps, thematic maps and other small-scale miscellaneous non-series maps. Historical vertical and horizontal sections, as well as indices to colours, are also included. The database comprises map metadata, including the title, theme, survey and revision years, publication years, mapped geological theme, base material, map function, colouration, approval status and the spatial extent of each map sheet. An accompanying file store contains high-resolution JPEG2000 scans for delivery, as well as various digital master and delivery formats. For a small number of maps, no scan exists. In total, the database contains over 240,000 scans of over 130,000 maps and field slips. The majority of the maps in the database cover Great Britain, but other regions are also represented, including a historical series of 1-inch maps of Ireland, 6-inch maps of the Isle of Man, 1:25 000 scale maps of the Channel Islands, and various overseas maps. The database contains a record of all geological maps produced by the British Geological Survey and its predecessors since the commencement of systematic geological mapping in the 1830s. The BGS Maps Database is mostly an archive of previous BGS maps, and is not the same as the latest BGS digital mapping. The maps within the database may differ significantly from BGS digital vector mapping. Further information about BGS digital vector mapping is available on the BGS website, under 'BGS Datasets'. The database has evolved over time, originally being a series of discrete databases. These databases have now been aggregated into a single dataset. BGS published maps, as well as 1:10 560 and 1:10 000 large-scale geological maps of England and Wales, and Scotland, are available through the BGS Maps Portal. Field slips and some thematic maps are not included on the BGS Maps Portal. The information about a map is normally a transcription from the map itself. Sometimes key information such as the title may not be actually printed on the map. Where this is the case the information is supplied in square brackets, e.g. [Kirk Maiden]. Information in square brackets means the information is supplied by the cataloguer and is not transcribed from the item.

Digitised version of aeromagnetic survey records of Great Britain comprising a record for each digitised point, supported by survey and 'ends and bends' based line indexes. Original records include flight line records, worksheets, contour sheets and air photos provided by contractors at completion of each survey. Worksheets digitised by BGS during 1980's Smith and Royles 1989.
