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.

The parish (from Latin 'Paroecia') is probably one of the most recognisable 'old' administrative boundary that many people are familiar with. The parish has always been associated with the administration of church and other ecclesiastical matters. The implementation of parishes as we would understand them today where imported into Wales by the Normans after the 1081. However many agree that there was likely a pre-existing system of church administration prior to the arrival of the Normans which may have been reused or provided a solid foundation for the Anglo-French system. It is from 12th century onwards that a comprehensive picture emerges. Ecclesiastical taxation records in 1254 and 1291 preserve parish names and many of these have continued up to the present day, albeit with some boundary changes.Ecclesiastical parishes were the main unit for tithe and Poor law payments, but by the late nineteenth century the Poor Law Amendment Act 1866 facilitated the need for the creation of 'Civic Parishes' which became the main administrative unit. In many instances these were based on the same boundaries as the ecclesiastical parishes, but changes were made to reflect the needs of growing urbanisation and populations rather than ecclesiastical requirements. The civil parishes where replaced in 1974 following the implementation of the Local Government Act 1972. This would see the civil parishes replaced by 'Communities' which are still in use today, although boundaries and names frequently continue to change. This dataset was created in Esri ArcPro 3.2.1 and reflects the historical hundred boundaries as recorded on the 2nd Edition Ordnance Survey 6" to the Mile County Series Mapping surveyed for Wales between 1888 and 1913.

This map is a mosaic image comprising of over 50 individual 1st Edition Ordnance Survey 25" to the Mile (1:2500) County Series sheets. These map cover the extent of the AHRC Deep Mapping Estate Archives project boundary straddling the counties of both Flintshire and Denbighshire. These maps were surveyed between 1869-1874. Each map sheet was georeferenced as part of the AHRC's Deep Mapping Estate Archives project in January 2022 using ESRI ArcPro 2.9.1 utilising multi-point georeferencing (around 250-600) control points as well as the spline transformation. Each map has then been mosaiced together into a single images and has been imported into ArcGIS online as a Joint Photographic Experts Group (JPEG) file and is available for public use under the Non-Commercial Open Government Licence.

This collection of polygonal data has been derived from the 1st Edition 25" (1:2500) Ordnance Survey County Series mapping which was surveyed between 1869-1874. The data consists of features such as trackways and earthwork features which were mapped by the OS but could not be included within the digital polygons as this would impact upon the acreage calculations. Instead these features have been mapped independently. The polygons has been generated from Modern Ordnance Survey Topographic Layer and have been altered to reflect the historical mapping source. This data was created as part of the AHRC's Deep Mapping Estate Archives project in January 2022 using ESRI ArcPro 2.9.1. The data has been imported into the ArcGIS online system as a shapefile and is available for public use under the Non-Commercial Open Government Licence.

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 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.

The primary objective from this project was to acquire historical shoreline information for all of the Northern Ireland coastline. Having this detailed understanding of the coast’s shoreline position and geometry over annual to decadal time periods is essential in any management of the coast.The historical shoreline analysis was based on all available Ordnance Survey maps and aerial imagery information. Analysis looked at position and geometry over annual to decadal time periods, providing a dynamic picture of how the coastline has changed since the start of the early 1800s.Once all datasets were collated, data was interrogated using the ArcGIS package – Digital Shoreline Analysis System (DSAS). DSAS is a software package which enables a user to calculate rate-of-change statistics from multiple historical shoreline positions. Rate-of-change was collected at 25m intervals and displayed both statistically and spatially allowing for areas of retreat/accretion to be identified at any given stretch of coastline.The DSAS software will produce the following rate-of-change statistics:Net Shoreline Movement (NSM) – the distance between the oldest and the youngest shorelines.Shoreline Change Envelope (SCE) – a measure of the total change in shoreline movement considering all available shoreline positions and reporting their distances, without reference to their specific dates.End Point Rate (EPR) – derived by dividing the distance of shoreline movement by the time elapsed between the oldest and the youngest shoreline positions.Linear Regression Rate (LRR) – determines a rate of change statistic by fitting a least square regression to all shorelines at specific transects.Weighted Linear Regression Rate (WLR) - calculates a weighted linear regression of shoreline change on each transect. It considers the shoreline uncertainty giving more emphasis on shorelines with a smaller error.The end product provided by Ulster University is an invaluable tool and digital asset that has helped to visualise shoreline change and assess approximate rates of historical change at any given coastal stretch on the Northern Ireland coast.

A county is a sub-national division of a country and where introduced by the Normans after the conquest of England in 1066, although a similar Anglo-Saxon administrative system of 'Shires' where in existence prior to this. Counties where usually overseen by a sheriff (Shire Reeve) who was appointed by the crown to collect taxes, raise militia and keep the peace though the administration of law. The implementation of the county system in Wales is a little complicated. In 1284 the Statute of Rhuddlan created six sheriffdoms or 'Shires' in Wales; Anglesey, Caernarfon, Merioneth, Flint, Carmarthen and Cardigan known as the Principality of Wales. The remainder of Wales consisted of the two Royal Lordships of Glamorgan and Pembroke and various Marcher Lordships which often made use of the earlier Commote and Cantref boundaries. The Marcher Lordships were abolished by the Laws in Wales Acts (1535) and the five new counties of Denbighshire, Monmouthshire, Brecknockshire, Radnorshire and Montgomeryshire were created to replace them. This created a total of thirteen historical counties in Wales. Some townships usually considered a part of Wales were assigned to Shropshire and Herefordshire and minor changes to the boundaries were made in the Laws in Wales Act (1542). The thirteen historic counties remained in use until the Local Government Act 1972, the implementation of which in 1974 saw the abolishment of the historic counties and the creation of eight new administrative counties, Clwyd, Dyfed, Gwent, Gwynedd, Mid Glamorgan, South Glamorgan, West Glamorgan and Powys. These themselves where replaced in 1996 by the creation of twenty two Unitary Authorities (or 'Principal Areas'), although the former eight counties still have ceremonial significance.

This polyline dataset has been derived from the 1st Edition 25" (1:2500) Ordnance Survey County Series mapping which was surveyed between 1869-1874. The data consists primarily of streams and drainage channels. The polylines has been traced to reflect the historical mapping source. This data was created as part of the AHRC's Deep Mapping Estate Archives project in January 2022 using ESRI ArcPro 2.9.1. The data has been imported into the ArcGIS online system as a shapefile and is available for public use under the Non-Commercial Open Government Licence.

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.

Towns have always played a key part in the administration of any area, that is both true of the past as it is true to this day. In the medieval period, many towns (often referred to as ‘Burhs’ or ‘Boroughs’) had the right of self-governing autonomy. This status was usually granted by the reigning monarch in the form of a town charter. These towns would often be able to appoint a member of parliament to represent the interests of the town and its residents. From the 15th century onwards, many town charters where reissued ushering in the foundation of town ‘corporations’. These entities would be responsible for the administration of the town usually under the jurisdiction of an appointed Mayor. Following the parliamentary reforms implemented by the Great Reform Act of 1832, attention was turned to the management of local government. A Royal Commission was established to assess the validity of these entities. It was concluded that may of these corporations where corrupt and not fit for purpose which led to the enactment of The Municipal Corporations Act 1835. This oversaw the creation of municipal boroughs that were to be governed by town councils which would be elected by ratepayers. The Ordnance Survey recorded some of these boundaries when undertaking their large scale mapping of Wales. Municipal boundaries where subsequently abolished and replaced in Wales by creation of ‘Districts’ following the Local Government Act 1972.

This polygonal dataset has been derived from the 1st Edition 25" (1:2500) Ordnance Survey County Series mapping which was surveyed between 1869-1874. The data consists of polygons which represent topographical features such as field parcels, buildings, roads etc., all of which reflect the historic landscape of the late 19th century. The polygons has been generated from Modern Ordnance Survey Topographic Layer and have been altered to reflect the historical mapping source. This data was created as part of the AHRC's Deep Mapping Estate Archives project in January 2022 using ESRI ArcPro 2.9.1. The data has been imported into the ArcGIS online system as a shapefile and is available for public use under the Non-Commercial Open Government Licence.

This map is a mosaic image comprising of several sheets, all of which depict the Ordnance Survey town plan for the town of Mold, Flintshire. This map was surveyed in 1871 at a scale of 1:500. Each individual map sheet was georeferenced as part of the AHRC's Deep Mapping Estate Archives project in February 2022 using ESRI ArcPro 2.9.1 utilising multi-point georeferencing (around 250-600) control points as well as the spline transformation. These maps where then mosaiced together into a single image which was then imported into ArcGIS online as a portable network graphics (PNG) file and is available for public use under the Non-Commercial Open Government Licence.
