These maps are based on the Ordnance Survey 'Old Series' One-Inch maps of England and Wales. They were the first 1:63 360 geological map series produced by the Geological Survey in England and Wales. Sheets were initially published as full sheets, and later as quarter sheets (NW, NE, SW, SE). Earlier maps are hand-coloured, later maps are colour-printed. The maps show both solid and drift geology. The OS 'Old Series' maps extended as far north as a line drawn between Preston and the Humber. To the north of this, the maps use the same sheetlines as the 1:63 360 New Series, and carry two sheet numbers, which refer to the Old Series (91-110) and New Series (1-73) numbering. These maps are common to both series. A sheet that covers the Isle of Man is also included in the series. Geological maps represent a geologist's compiled interpretation of the geology of an area. A geologist will consider the data available at the time, including measurements and observations collected during field campaigns, as well as their knowledge of geological processes and the geological context to create a model of the geology of an area. This model is then fitted to a topographic basemap and drawn up at the appropriate scale, with generalization if necessary, to create a geological map, which is a representation of the geological model. Explanatory notes and vertical and horizontal cross sections may be published with the map. Geological maps may be created to show various aspects of the geology, or themes. 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.

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.

This dataset contains scans of Applied Geology Maps (AGMs) and sections, which are also known as thematic maps, Environmental Geology Maps (EGMs) or Planning for Development Maps (PfD). They were produced as part of 'Geological Background for Planning and Development' and preliminary sand and gravel projects carried out by the British Geological Survey for the Department of the Environment, Transport and the Regions (DETR), the Scottish Development Department and Scottish Office from 1975 to 1996. The maps and sections cover a number of themes (up to 22) for specific areas relating to the project area within the United Kingdom (which are mostly urban areas). Themes include simplified bedrock and superficial maps, drift thickness, drift lithology, rockhead contours and a range of mining-related themes. Each area had its own custom set of maps and were issued with an accompanying BGS Technical Report. The maps and report were sometimes issued as a pack, but for some areas they were made available separately. The geological linework and the methods used to produce the maps are those current at the time of production. Map scales are predominantly 1:10 000 or 1:25 000, with a few 1:50 000 maps. The maps have Ordnance Survey map bases and are bounded by the project area. The maps could be used for geological, engineering geological, environmental and resources research, as an information and reference resource and for inclusion in reports and papers. These maps are hard-copy paper records and digital scans, stored in the National Geoscience Data Centre (NGDC).

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.

The UTM series of maps are based on 1:250 000 base maps published by the Ordnance Survey. Mapping is divided into squares which cover 1 degree by 1 degree of latitude / longitude in the Universal Transverse Mercator (UTM) projection, and coverage extends offshore and onto the continental shelf. The UTM series are available in three different themes: - Solid geology (complete coverage within the mapped area, including most of the UK continental shelf) - Sea bed sediments (coverage for most offshore areas) - Quaternary geology (coverage for the UK sector of the North Sea, Irish Sea and the Atlantic margin) Also included within this series are two small-scale (1:500 000) bedrock geology maps of the Central Rockall Basin and North Rockall Basin. These maps supersede the older quarter-inch series of maps which were published for England / Wales and Scotland. Geological maps represent a geologist's compiled interpretation of the geology of an area. A geologist will consider the data available at the time, including measurements and observations collected during field campaigns, as well as their knowledge of geological processes and the geological context to create a model of the geology of an area. This model is then fitted to a topographic basemap and drawn up at the appropriate scale, with generalization if necessary, to create a geological map, which is a representation of the geological model. Explanatory notes and vertical and horizontal cross sections may be published with the map. These maps are, for the most part, hard-copy paper records stored in the National Geoscience Data Centre (NGDC) and are delivered as digital scans through the BGS website.

A series of maps at the detailed scale of 1:25 000 have been produced for areas of outstanding geological interest in Great Britain. Some maps are accompanied by explanatory booklets. The maps were published between 1954 and 2007. About 60 maps have been published, some showing solid geology, some drift geology and some combined solid and drift. Most of the maps include geological cross sections and generalised vertical sections. Geological maps represent a geologist's compiled interpretation of the geology of an area.

The collection of map series held by BGS which correspond to the outputs of discrete projects. The maps often focus on a specific theme, and / or may have limited spatial coverage. The thematic maps include the following series: Applied Geology Maps (AGMs), also known as Environmental Geology Maps (EGMs) or Planning for Development maps, which were produced between 1975 and 1996 as part of 'geological background for planning and development' and preliminary sand and gravel projects carried out on behalf of the Department of the Environment, Scottish Development Department and the Scottish Office. Industrial Minerals Assessment Unit (IMAU) Mineral Assessment Report maps, published between 1971 and 1985 by the Institute of Geological Sciences. Oil-shale Seam Maps of the Lothians, published between 1977 and 1982 by the Institute of Geological Sciences (IGS) in Edinburgh.

For much of the Geological Survey's existence, the County Series of maps were the standard large-scale maps on which geological mapping was undertaken. These maps are based on the Ordnance Survey County (or six-inch to the mile) series of maps. These maps were cut up to be used in the field to record geological observations, and on return to the office, the geology was transferred to a complete County Series map, which after approval was known as a 'standard' (England / Wales) or 'clean copy' (Scotland). This dataset contains the 'standard' or 'clean copy' County Series maps held by BGS. Geological maps represent a geologist's compiled interpretation of the geology of an area. A geologist will consider the data available at the time, including measurements and observations collected during field campaigns, as well as their knowledge of geological processes and the geological context to create a model of the geology of an area. This model is then fitted to a topographic basemap and drawn up at the appropriate scale, with generalization if necessary, to create a geological map, which is a representation of the geological model. Explanatory notes and vertical and horizontal cross sections may be published with the map. Geological maps may be created to show various aspects of the geology, or themes. The most common map themes held by BGS are solid (later referred to as bedrock) and drift (later referred to as superficial). 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.

A collection of hydrogeological maps created by the British Geological Survey between 1967 and 1994. The maps in the collection cover aspects of groundwater availability, exploitation and quality, and were published at various scales from 1:25 000 to 1:625 000. A hydrogeological map is a specialized type of map that illustrates the distribution and characteristics of hydrogeological features in a particular area. Hydrogeological maps of the UK provide information on major aquifers, including geological and lithological information, surface drainage systems and water quality issues. The 23 maps show information on surface water features, the three dimensional geometry of aquifers, groundwater levels, abstractions and quality including saline intrusion in varying amounts of detail. They range in scale from 1:625 000, for the national map of the hydrogeology of England and Wales, down to 1:25 000 for some of the smaller regional maps. These maps are important tools for understanding and managing groundwater resources, as well as for addressing water-related environmental issues. 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.

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.
