This dataset comprises 2 collections of maps. The facsmile collection contains all the marginalia information from the original map as well as the map itself, while the georectified collection contains just the map with an associated index for locating them. Each collection comprises approximately 101 000 monochrome images at 6-inch (1:10560) scale. Each image is supplied in .tiff format with appropriate ArcView and MapInfo world files, and shows the topography for all areas of England, Wales and Scotland as either quarter or, in some cases, full sheets. The images will cover the approximate epochs 1880's, 1900's, 1910's, 1920's and 1930's, but note that coverage is not countrywide for each epoch. The data was purchased by BGS from Sitescope, who obtained it from three sources - Royal Geographical Society, Trinity College Dublin and the Ordnance Survey. The data is for internal use by BGS staff on projects, and is available via a customised application created for the network GDI enabling users to search for and load the maps of their choice. The dataset will have many uses across all the geoscientific disciplines across which BGS operates, and should be viewed as a valuable addition to the BGS archive. There has been a considerable amount of work done during 2005, 2006 and 2007 to improve the accuracy of the OS Historic Map Collection. All maps should now be located to +- 50m or better. This is the best that can be achieved cost effectively. There are a number of reasons why the maps are inaccurate. Firstly, the original maps are paper and many are over 100 years old. They have not been stored in perfect condition. The paper has become distorted to varying degrees over time. The maps were therefore not accurate before scanning. Secondly, different generations of maps will have used different surveying methods and different spatial referencing systems. The same geographical object will not necessarily be in the same spatial location on subsequent editions. Thirdly, we are discussing maps, not plans. There will be cartographic generalisations which will affect the spatial representation and location of geographic objects. Finally, the georectification was not done in BGS but by the company from whom we purchased the maps. The company no longer exists. We do not know the methodology used for georectification.

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.

This research project aimed to fill a major lacuna militating against the effective exploitation of many post-medieval to mid-Victorian historical sources collected by local administrative areas: the lack of information on the boundaries of those administrative areas, the so-called 'historic' or 'ancient' parishes of England and Wales. It is known that these districts came into being during the Middle Ages, that the map of these ecclesiastical parishes was essentially complete by the fifteenth century, that these ecclesiastical boundaries were adopted during the early modern period for secular and judicial purposes, and that boundaries remained essentially unchanged until a number of reforms from the mid-nineteenth century onwards reorganised the local administrative geography of the country. The project aimed to reconstruct those boundaries as they were before the post-nineteenth century changes.

Latest update: October 2025 Updated Boundaries of Ancient Woodland polygons covering England. This is the updated spatial dataset that describes the geographic extent and location of ancient woodland in England (excluding the Isles of Scilly). Ancient Woodland features will be approved county-by-county for publication throughout the first year of production until the data product coverage extends across England. Where available this dataset takes precedence over the Ancient Woodland – England dataset. The update revises the inventory to address problems and gaps in the previous iteration. Technological advances mean that small ancient woodlands (0.25-2ha) are being represented within the inventory for the first time as well as wood pasture and parkland being represented as its own category. The inventory identifies ancient woodland sites in England. Ancient woodland is identified by studying the presence or absence of woods from historic maps, information about the wood's name, shape, internal boundaries, location relative to other features, ground survey, and aerial photography. The information recorded about each wood and stored on the Inventory Database includes its grid reference, its area in hectares and how much is semi-natural or replanted. Prior to the digitisation of the boundaries, only paper maps depicting each ancient wood at 1:50 000 scale were available. Attribution statement: © Natural England 2024. Contains OS data © Crown copyright and database rights 2024. OS AC0000851168. It includes Ancient Semi-Natural Woodland (ASNW), which retains a native tree and shrub cover; Plantation on Ancient Woodland Sites (PAWS), where the original tree cover has been felled and replaced by planting, often with conifers; Ancient Wood Pasture (AWPP), where the trees are managed in tandem with a long established tradition of grazing, characteristically with at least some veteran trees or shrubs or; Infilled Ancient Wood Pasture (IAWPP) which has become infilled with trees arising from planting or natural regeneration. The AWI Update project will deliver an accurate inventory of the entirety of England’s ancient woodland resource, including those woods smaller than 2ha which are currently not mapped on the AWI. It will also ensure that the AWI is used and respected by planners, developers, land managers and all those who make and use spatial plans in England’s countryside. Lineage The ancient woodland boundaries are digitised to OS MasterMap - assessed by licencing staff as suitable for OS Presumption to Publish process. However, the maps that Ancient Woodlands are based upon include the OS 1” First Edition maps, the OS 1:25 000 and the OS 1:50 000 maps. The boundaries cannot be taken as precise, especially where they are surrounded by woodland, and are only precisely comparable with other boundaries at the 1” map scale (1:63 360). The inventory identifies over 22,000 ancient woodland sites in England. Ancient woodland is identified using presence or absence of woods from old maps, information about the wood's name, shape, internal boundaries, location relative to other features, ground survey, and aerial photography. The information recorded about each wood and stored on the Inventory Database includes its grid reference, its area in hectares and how much is semi-natural or replanted. Prior to the digitisation of the boundaries, only paper maps depicting each ancient wood at 1:50 000 scale were available. The datasets consulted: OS MasterMap, OS First Edition Maps (Historic County Series Maps Epoch 1-4), Historic OS Drawings, Aerial Imagery, Original AWI Datasheets, Open Source old historical maps (varies depending on county agreements), BSBI Indicator species data, County Tithe Maps, Forestry Commission National Forest Inventory and Forest Condition Survey. Besides the isolated and modified woodland boundaries derived from OS MasterMap that have been identified Ancient Woodland, additional third party data is viewed for informative purposes only during the creation of the project layer. No data from any other of these third party sources is copied, transferred or viewable in the layer to be published."

This project systematically processed high-resolution and manuscript historical maps to unlock a dormant body of information about the historical development of cities and regions during periods of structural economic transformation.

The work was organised across six interlinked work packages, combining empirical and theoretical analysis in the UK, France, and Canada. Outputs included peer-reviewed publications and robust algorithms for extracting spatial data from historical sources, contributing valuable tools and insights to the fields of urban economics and economic history.

This data package contains three segmentation codes designed to extract features and segment historical maps.

Little is known about the patterns of city development during the structural transformation of economies. This project will systematically process high-resolution and manuscript historical maps to make a dormant body of information about our cities' and regions' past accessible.

The proposed research will advance our understanding of long-run urban growth through the development of three innovative methodologies, which will overcome practical limitations of historical data sources: 1) A technique to extract land use patterns from historical colour maps applied to France (1750-1950); 2) A recognition algorithm to detect, tag and geo-locate points of interest in historical high-quality maps of the 70 largest urban centre in England and Wales; 3) An algorithm to geo-locate address information from Micro-censuses and trade registers.

We have identified four main research questions that will be developed in the following separate research projects. In Project 1, the main question is: what are the long-term empirical patterns of urban development, most notably the persistence of the spatial organisation of economic activity and the role of building infrastructure in shaping such persistence? In Project 2, the main question is: How do environmental disamenities and their unequal distribution within cities affect the spatial organisation of consumption amenities and production? In Project 3, the main question is: Do cities grow towards their bad parts, their neighbourhoods with the lowest environmental amenities? In Project 4, the main question is: How does vertical growth and advances in building technologies affect the spatial organisation of cities?

To address these research questions, we will organise our workflow in six inter-connected work packages (WP):

WP1--Classification of land use in France (1750-2015): The objective of WP1 will be to recover land use information at a fine scale from digitised maps using state-of-the-art machine learning techniques;

WP2--Digitisation of micro-features embedded in Ordnance Survey (OS) city maps of England and Wales (1870-1960);

WP3--Geo-localization of residents and production units in England and Wales (1851-1911);

WP4--Dynamic model of city growth with persistent building stock: WP4 builds a general equilibrium model of spatial economic activity that embeds the durability of housing and infrastructure and exploits the three hundred years of population settlement data produced in WP1;

WP5--Pollution and the long-run development of cities: WP5 builds on WP2,3 and proposes to study the joint dynamics of residential sorting and the location of production within cities to understand how a major environmental disamenity-industrial pollution-affects the spatial organisation of cities in the longer-run;

WP6--Horizontal and vertical urban growth in Montreal and Toronto: WP6 will bridge between the previous working packages WP1, WP2, WP4 and WP5, and study--empirically and theoretically--horizontal and vertical urban growth.

The project will be jointly led by three teams. The French team will be composed of Gobillon (PI), Combes (CoI) and Duranton (TM) who have contributed to the development of major theoretical approaches in urban economics. The Canadian team will be led by Heblich (PI), who is a lead researcher in urban economics/economic history, and Fortin (Co-I), a lead in GIS analysis. The UK team will be led by Zylberberg (PI), who is an economist specialist in data extraction form historical sources and remote sensing. Shaw-Taylor and Schürer, advisory board, will help design the analysis of the population micro-censuses between 1851 and 1911 (WP3). The collaboration partner, Redding (TM), involved in the design of WP3 and the implementation of WP6, is one of the World lead researchers in urban economics.

Outputs will include articles in top economic journals, and detailed algorithms to extract relevant spatial information from manuscript maps.

These maps are based on the Ordnance Survey quarter-inch to the mile series of maps, for England / Wales and Scotland. Most maps in this series show solid geology only, but there are a few drift maps within the New Series maps of England / Wales. There are three distinct series of quarter-inch maps: - Geological map of England and Wales. Quarter-inch series 1:253 440: Old Series (1889 - 1906). This is a set of hand-coloured maps which were published between 1889 and 1895 with later revisions. They were engraved onto copper. The series was issued as 15 sheets, where sheet 3 was an index to colours. - Geological map of England and Wales. Quarter-inch series 1:253 440: New Series (1906-1977). Following the popularity of the Old Series 'Quarter-inch' map, a New Series of colour-printed maps was issued. This was a long-lived series, with sheets still being published in the late 1970s. Maps were published between 1906–1977. The series was issued as 15 sheets, where sheet 3 was an index to colours. - Geological Survey of Scotland. Quarter-inch series 1:253 440 (1904-1977). These Scottish maps were published in parallel with the English / Welsh New Series, and was issued as 17 sheets. The quarter-inch mapping was superseded in the 1970s - 1980s by the Universal Transverse Mercator (UTM) Series geological maps of the UK and Continental Shelf. 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.

This layer of the map based index (GeoIndex) shows the availability of 1:63360 scale geological maps. The maps are available for most of England and Wales and show early geological mapping covering the OS Old Series one inch map sheet areas.

This is a spatial dataset that defines the non-designated geographic extent and location of Historic Parklands in England, as depicted in the OS Historic Maps (2nd Edition and Hills Edition). Regularly updated aerial imagery has been used to ensure high spatial accuracy. The mapping scale is 1:1,000. This dataset, alongside the designated landscapes within the Historic England Registered Parks and Gardens layers, and HER searches can provide a comprehensive understanding of the maximum historic extent of Parklands.Historic parklands are uniquely placed to deliver integrated multi-objective benefits for the historic and natural environments. They are a finite and non-renewable resource, and they remain working landscapes. Through active management, their countless interests can be secured to great public benefit.This dataset was developed using multiple reference layers, each contributing unique value. The layers are listed below in order of precedence for decision-making:Aerial Photography of Great Britain – High-resolution imagery used for precise boundary verification of historic parklands.OS 2nd Edition Historic Map (1888–1913) – Detailed topographic maps capturing landscape changes during the late Victorian and Edwardian periods, with a - particular focus on Parks and Ornamental Grounds.OS Hills Edition Historic Map (1885–1903) – One-inch-to-the-mile maps with shaded relief, providing insights into terrain and historical land use, with a specific emphasis on Parks and Ornamental Grounds.HE Registered Parks and Gardens (RPG) – Contains designated historic parkland names and boundaries.NE Wood Pasture and Parkland – Represents vegetation structure rather than historic features, used selectively when other sources are unavailable, although it has limited relevance for defining parkland boundaries.NE Ancient Woodland – Depicts ancient woodlands but has limited relevance for defining parkland boundaries.NE Historic Parkland – A pre-existing dataset with low spatial accuracy and no metadata, serving as a reference layer for areas requiring review (targeting only).Attribution Column Heading Full Name Format Description

Historic Flood Map is a GIS layer showing the maximum extent of all individual Recorded Flood Outlines from river, the sea and groundwater springs and shows areas of land that have previously been subject to flooding in England. Records began in 1946 when predecessor bodies to the Environment Agency started collecting detailed information about flooding incidents, although we may hold limited details about flooding incidents prior to this date. This dataset differs from the Recorded Flood Outline dataset in that it contains only those flood outlines that are 'considered and accepted' if the following criteria are met:photographic/video evidence with the location referencedrecorded flood levels with the location referencedevidence that the outline represents the time of peak water level (for example date / time stamped photo)evidence that the source of flooding is from rivers, the sea or groundwater and not surface water/overland runoff. The absence of coverage by the Historic Flood Map for an area does not mean that the area has never flooded, only that we do not currently have records of flooding in this area. It is also possible that the pattern of flooding in this area has changed and that this area would now flood under different circumstances. The Historic Flood Map will take into account of the presence of defences, structures, and other infrastructure where they existed at the time of flooding. It will include flood extents that may have been affected by overtopping, breaches or blockages. Flooding shown to the land and does not necessarily indicate that properties were flooded internally. The Historic Flood Map consists of spatial data only.

The 1:63 360 / 1:50 000 scale map series are the most useful scale for most purposes. They provide almost complete coverage of onshore Great Britain. The BGS collection of 1:63 360 and 1:50 000 scale maps comprises two map series: - Geological Survey of England and Wales 1:63 360 / 1:50 000 Geological Map Series [New Series]. These maps are based on the Ordnance Survey One-inch New Series topographic basemaps and provide almost complete coverage of England and Wales, with the exception of sheet 180 (Knighton). The quarter-sheets of 1:63 360 Old Series sheets 91 to 110 coincide with sheets 1 to 73 of the New Series maps. These earlier maps often carry two sheet numbers which refer to the Old Series and the New Series. - Geological Survey of Scotland 1:63 360 / 1:50 000 Geological Map Series. These maps are based on the Ordnance Survey First, Second, Third and Fourth editions of the One-inch map of Scotland. The maps used the most recent topographic basemap available at the time. In the Western Isles, one-inch mapping was abandoned and replaced by maps at 1:100 000 scale, which are associated with this series. Sheets were traditionally issued at 1:63 360 scale, with the first 1:50 000 maps appearing in 1972. Sheets at 1:50 000 scale may be either facsimile enlargements of an existing 1:63 360 sheets, or may contain new geology and cartography. The latter bear the additional series designation '1:50 000 series'. Within the Scottish series, new mapping at 1:50 000 scale was split into east and west sheets. For example, the original one-inch sheet 32 became 1:50 000 sheets 32E and 32W. A number of irregular sheets were also introduced with the new 1:50 000 scale mapping. There are a number of irregular special sheets within both 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. 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.

In the middle of 2001 Roger Kain and Richard Oliver, from the University of Exeter, published a substantial work entitled Historic Parishes of England and Wales: Electronic Map - Gazetteer- Metadata. This was the final product of a project aimed at locating and mapping the boundaries of parish and sub-parish units of the mid-nineteenth century. The authors published the results in a series of electronic maps supplied on CD-ROM. Each one of these 115 maps contain a scanned 1”:1 mile OS New Popular Series map, overlain by the boundaries. A reference number can be found in each of the polygons that can then be used to look up information about that parish in gazetteer in an accompanying book.

A major limitation of this work is that although the boundaries are in digital form, they are divided into 115 tiles, none of which have any spatial co-ordinate information inherent in them. This means that although the maps are invaluable as a reference tool, they can not be used together within a GIS to select, analyse and present historic information.

We have therefore created a single digital map of the boundaries to provide a single, continuous coverage of polygons, each of which contain the information provided by Kain and Oliver in their accompanying book. This information includes the parish name, Ancient County, and a reference number that coincides with entries for that parish in the 1851 census report.

It is recommended that users also order disc 1 of study 4348; Historic Parishes of England and Wales : an Electronic Map of Boundaries before 1850 with a Gazetteer and Metadata

Please note: this study does not include information on named individuals and would therefore not be useful for personal family history research.

ArcGIS shapefile of 288 polygons providing boundary and attribute data for the fifty-five ancient counties of England and Wales as given in the 1831 census for England and Wales. As such this represents the counties of England and Wales as they were before the boundary changes caused by the Counties (Detached Parts) Act, 1844 (7 & 8 Vict. c. 61) which led to the elimination of some of the detached portions of counties.

These data were created as part of a research program directed by Leigh Shaw-Taylor and Tony Wrigley, which aims ultimately to reconstruct the evolution of the occupational structure of Britain from the late medieval period down to the early twentieth century.

Colourful and easy to use, Bartholomew’s maps became a trademark series. The maps were popular and influential, especially for recreation, and the series sold well, particularly with cyclists and tourists. To begin with, Bartholomew printed their half-inch maps in Scotland as stand-alone sheets known as 'District Sheets' and by 1886 the whole of Scotland was covered. They then revised the maps into an ordered set of 29 sheets covering Scotland in a regular format. This was first published under the title Bartholomew’s Reduced Ordnance Survey of Scotland. The half-inch maps of Scotland formed the principal content for Bartholomew's Survey Atlas of Scotland published in 1895. Bartholomew then moved south of the Border to the more lucrative but competitive market in England and Wales, whilst continuing to revise the Scottish sheets. This Bartholomew series at half-inch to the mile, covered Great Britain in 62 sheets in the 1940s, Bartholomew’s first to cover Great Britain at this scale (their previous series covering Scotland and then England and Wales). The series provides an attractive and useful snapshot of 1940s Britain. By this time, Bartholomew had altered the range of information on their maps compared to the 1900s. There were more categories of roads, Ministry of Transport road numbers were added, and new recreational features such as Youth Hostels and Golf Courses. Bartholomew’s topographic information was gathered partly from original Ordnance Survey maps, and partly from information sent in to Bartholomew from map users. One important user community for Bartholomew were cyclists. From the 1890s, Bartholomew entered into a formal relationship with the Cyclists’ Touring Club, then numbering around 60,500 cyclists, proposing that club members supplied Bartholomew with up-to-date information. In return, Bartholomew provided the CTC with discounted half-inch maps. The relationship worked very well, turning CTC members into an unofficial surveying army, feeding back reliable and accurate topographical information which Bartholomew would then use to update their maps. You can read more about this and see selected letters from cyclists at: http://digital.nls.uk/bartholomew/duncan-street-explorer/cyclists-touring-club.html.

Usually Bartholomew made revisions the sheets right up to the time of publication, so the date of publication is the best guide to the approximate date of the features shown on the map. You can view the dates of publication for the series at: https://maps.nls.uk/series/bart_half_great_britain.html

The Historic Environment Opportunity Map for New Woodland dataset identifies areas in England that may be suitable for new woodland, based solely on available Historic Environment data. The dataset categorises land by different opportunity ratings to reflect the potential suitability of land for woodland creation while acknowledging areas of uncertainty due to data availability.

The purpose of this dataset is to guide landowners, planners, and decision-makers in considering woodland creation from a historic environment perspective. It should be noted that this dataset only considers the Historic Environment and therefore the opportunity ratings do not guarantee or preclude approval for woodland creation proposals.

As any forestry proposal could have the potential to affect the Historic Environment you should contact your local historic environment service. The local historic environment service can provide further data to support woodland creation proposals.

NHLE is the official, up to date register of all nationally protected historic buildings and sites in England.

SHINE is a single, nationally consistent dataset of non-designated historic and archaeological features from across England that could benefit from land management schemes.

The opportunity ratings are as defined:

· Favourable - Areas deemed suitable for new woodland on consideration of available Historic Environment data.

· Neutral - Areas deemed neither favourable nor unfavourable for new woodland on consideration of available Historic Environment data. Proposals in these areas will require additional consideration of the Historic Environment on a case-by-case basis.

· Unclassified - Areas, where SHINE data has been supplied, with no assigned opportunity rating. This illustrates a current absence of recorded data from a Historic Environment perspective. However, as SHINE data is included in the dataset for this area, a degree of confidence may be inferred when considering the absence of historic environment features.

· Unclassified (No SHINE supplied) - Areas, where SHINE data has not been supplied, with no assigned opportunity rating. This illustrates a current absence of recorded data from a Historic Environment perspective.

· Unsuitable - Areas deemed unsuitable for new woodland on consideration of available Historic Environment data.

Unclassified areas may be suitable or unsuitable for new woodland. To better understand these areas, contact the local historic environment service in accordance with the UKFS and Historic Environment Guidance for Forestry in England - GOV.UK

The datasets included in each opportunity rating are as follows:

Favourable

· Lost Historic Woodlands (ArchAI/Forestry Commission) – An A.I. dataset that identifies areas of woodland depicted on early 20th Century Ordnance Survey mapping which have since been lost.

Neutral

· Historic Parklands (Zulu Ecosystems) – an A.I. dataset that identifies areas of parkland depicted on early 20th Century Ordnance Survey mapping.

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.
