BGS Geophysical maps
A collection of 1:250 000 scale geophysical maps in the Universal Transverse Mercator (UTM) projection, covering the United Kingdom and continental shelf areas between 1975 – 1990. Mapping is divided into squares which cover 1 degree by 1 degree of latitude / longitude. A geophysical map is a graphical representation of data collected through various geophysical methods to investigate the subsurface characteristics of the Earth. Geophysics is the study of the physical properties and processes of the Earth using measurements of physical quantities such as gravity, magnetic fields, seismic waves, electrical resistivity, and others. The collection includes aeromagnetic anomaly maps (1975 – 1990), Bouguer gravity anomaly maps (1975 – 1989) and a small number of free air anomaly maps (1981 – 1989). These maps are hard-copy paper records stored in the National Geoscience Data Centre (NGDC) and are delivered as digital scans through the BGS website.

BGS Maps Portal
- The BGS Maps Portal provides access to over 45 000 high-resolution viewing images of almost all the small, medium and large scale maps produced by the BGS since mapping started in 1832 right up to the most recent maps released in 2020. It incorporates all the earlier maps and history pages that were previously made available through the BGS ‘Historical maps of the Geological Survey of Great Britain and Ireland’ web resource.

Data Quality
Maps created by the British Geological Survey between 1975 - 1990. The paper maps were scanned to TIF image format at 300 dpi as part a scanning project from c. 2000 to the present day. JPEG2000 and PDF derivatives were created from the master TIF scans.
