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. Between 1955 and 1965 an airborne magnetic survey was conducted covering the land and parts of the sea areas of the United Kingdom. Different sections of the survey were conducted in different years by Hunting Geology and Geophysics Ltd. (variously Hunting Surveys Ltd. or Hunting Geophysics Ltd.) and Canadian Aeroservices Inc. The survey was funded by the Department of Scientific and Industrial Research and, in Northern Ireland, by the Department of Commerce. For the first year of survey funds were also provided by the Nuffield Foundation. The survey was overseen by the Geophysics Department of the (then) Geological Survey and Museum (subsequently Institute of Geological Sciences, subsequently British Geological Survey), in collaboration with the United Kingdom Atomic Energy Authority, Harwell, when local radiometric surveys were incorporated.

Flight-line/contour-line intercepts were subsequently digitised from these maps to produce the digital aeromagnetic data set for the UK, comprising over 540 000 points. The data has been reprocessed to refer anomalies to a variant of IGRF-90, which makes allowance for the inaccurate prediction of the geomagnetic field model prior to 1971. Most of the surveys had a flight-line spacing of 2 km, with 10 km tie-lines. Flight lines for each survey were north to south or east to west, depending on the predominant geological strike, and most of the country was flown at 1000 ft (305 m) mean terrain clearance. 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.
