[This metadata record has been superseded, see http://data.bgs.ac.uk/id/dataHolding/13603141] These are scanned and georeferenced raster versions of the 1400 Ministry of Housing and Local Government (MHLG) Mineral Planning Permissions Maps (see associated metadata). The 1:25000 scale maps recorded hand drawn boundaries for permitted, withdrawn and refused mineral planning permissions and worked ground for every local authority area in England. Accompanying the maps is an associated card index (see metadata for MHLG Cards). The mineral planning permission polygons recorded on the maps have been digitised to create vector GIS polygons (see associated metadata for MHLG Planning Permission Polygons).

The Index to the Primary Geological Data resulting from Open Cast Coal exploration. The index lists the content of the boxes of data, including reports, interpretations and records of research in British coalfield areas. The Index lists information on past and current workings and for future prospects. The majority of the collection was deposited with the National Geological Records Centre by the Coal Authority in July 2001, but a small number of BGS records have been added subsequently.

Many mineral resource maps for areas of Great Britain at scales of 1:25 000 and 1:50 000 have been produced by the British Geological Survey and its predecessors. Many of these maps were produced by the Industrial Minerals Assessment Unit (IMAU) from 1971 to 1986. Most maps cover a single 10 km x 10 km grid square, but some cover larger areas. The majority of maps are sand and gravel resource maps, but conglomerate, limestone, dolomite and celestite are also covered in certain regions. The maps show the locations of IMAU mineral resource blocks, the locations and categories of resource deposits and the locations of boreholes with indicative logs. A series of technical reports (Mineral Assessment Reports, MARs) was also created alongside the maps. Refer to the metadata entry for the Mineral Assessment Reports for more information. The maps are intended to be used for resource development, strategic planning, land-use planning, the indication of hazard in mined areas, environment assessment and as a teaching aid. The data was originally published in printed map form. The printed maps have been scanned and added to the BGS Maps Database.

A card index storing supplementary information regarding name, operator, dates and commodity worked for each planning permission boundary recorded (drawn) on the Ministry of Housing and Local Government (MHLG) Mineral Planning Permissions Maps (see associated metadata). Information on the cards has been used to attribute the Ministry of Housing and Local Government (MHLG) Mineral Planning Permission Polygons (see associated metadata for MHLG Planning Permission Polygons).

The BGS collection of 1:10 560 / 1:10 000 National Grid Series geological maps. These maps are based on the Ordnance Survey National Grid series of maps, which are defined by the 10 km intervals of the larger 100 km square identified by a specific two-letter code. Each map is thus denoted by a unique reference, e.g. SP 29 NW. SP=100 km square; 29=10 km square; NW=5 km square. Since field mapping is generally undertaken at the scale of 1:10 000 (or equivalent), these maps are the largest-scale main series of geological maps that BGS holds. A small number of remote areas were mapped at 1:25 000 scale, the subsequent maps are also at 1:25 000 scale and are included in this series. The equivalent to the National Grid Series prior to the 1960s is the County Series (at 1:10 560 scale). In the 1960s, this series started to be replaced by 6 inches to 1 mile (1:10 560 scale) National Grid sheets based on the four quadrants (NW, NE, SW, SE) of a 10 km Ordnance Survey National Grid square. Areal coverage provided by the National Grid series of large-scale maps is limited in extent and the preceding County series of six-inch maps can still be the most up to date map available for some areas. 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, 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 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.

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.

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 approximately 1400 Ordnance Survey 1:25 000 paper maps upon which the former Ministry of Housing and Local Government (MHLG) recorded hand drawn boundaries for permitted, withdrawn and refused mineral planning permissions and worked ground for every local authority area in England. Accompanying the maps is an associated card index (see metadata for MHLG Cards). Priority was placed on areas that had given rise to then current casework issues, so at the time when the maintenance of the maps ended, some authority information had been updated recently whereas other areas had not been visited for many years. Therefore, the variable completeness of the data should be kept in mind when the material is being used. Both the maps and the card index have been used to create the digital mineral planning permissions polygons (see metadata for MHLG Planning Permission Polygons). Polygons for worked ground have not been captured.
