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.

This Web service provides layers which are spatial indexes to the coverage of BGS (British Geological Survey) geological, geophysical, and hydrogeological maps from various different map series held by BGS in the National Geoscience Data Centre (NGDC). The layers include the spatial footprint of each map, and metadata including the map title, map series, nominal survey year, copyright year, scale, base material, colouration, the availability of an image, and, if available, a link to an image of the map. It includes maps from the start of systematic geological survey work in the 1830s, through to more recent BGS mapping. The maps referenced by this Web service are historical, and are not the same as the latest digital geological mapping from BGS.

A collection of small-scale non-series maps which offer whole-country coverage of the United Kingdom 1856-2013. Included in the collection are geological, tectonic, structural, mineral resource and geophysical maps, together with a small number of historical facsimile maps. Key geological maps included in the collection which ran to many editions are Geology of the British Islands 1:584 000 and the Geological Map of Great Britain 1:625 000. 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.
