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.

September 2017 OS Code-Point Open for Greater London and London boroughs are downloadable via the links below.

OS Code-Point Open provides a National Grid coodinate for a point within each postcode unit (e.g. SE1 2AA) in Great Britain.There are approximately 1.6 million postcode units in the UK and each contains an average of 15 adjoining addresses. It also contains a number of columns of attributes which provide information about each postcode unit, including local authority area codes down to ward level and National Health Service.

The geographic extent of the Code-Point dataset below has been limited to the Greater London area as well as extracts for the City of London and the 32 London boroughs individually. In addition to conventional CSV file format, the dataset is also available as ESRI shapefile format (.shp) for ease of use with Geographical Information Systems (GIS) for visualisation and further analysis.

Key attributes: postcode unit, easting, northing, NHS health authority code and administrative codes

Coverage: Greater London and 33 individual London borough.

Format: Comma separated values (.csv) & Esri shapefile (.shp)

Ordnance Survey ® OpenMap - Local Functional Sites are polygon features that represent the area or extent of certain types of function or activity across England, Wales and Scotland. Functional Sites are classified into five main themes:

Air Transport - This theme includes all sites associated with movement of passengers and goods by air, or where aircraft take off and land. Includes: Airfield, Airport, Helicopter Station, Heliport. Education - This theme includes a very broad group of sites with a common high-level primary function of providing education (either state funded or by fees). Includes: Primary Education, Secondary Education, Special Needs Education, Non State Primary Education, Further Education, Higher or University Education, Non State Secondary Education Medical Care - This theme includes sites which focus on the provision of secondary medical care services. Includes: Medical Care Accommodation, Hospital, Hospice Road Transport - This theme includes: Bus Stations, Coach Stations, Road user services. Water Transport - This theme includes sites involved in the transfer of passengers and or goods onto vessels for transport across water. Includes: Port consisting of Docks and Nautical Berthing, Vehicular Ferry Terminal, Passenger Ferry Terminal.

With OS OpenMap - Local Functional Sites you can:

Understand your area in detail, including the location of key sites such as schools and hospitals. Share high-quality maps of development proposals to help interested parties to understand their extent and impact. Analyse data in relation to important public buildings, roads, railways, lines and more. Use in conjunction with other layers such as Important Buildings - buildings that fall within the extent of a Functional Site. Present accurate information consistently with other available open data products. The currency of the data is 04/2025

Place-names represent a fundamental geographical identifier, which also have considerable cultural, historical and linguistic importance. Scotland had a great tradition of publishing descriptive (long-form) gazetteers in the 19th century. This dataset is the GIS point format output from a project funded by the Scottish Government in the early 2010s, to create a Definitive Place-Name Gazetteer for Scotland, which helped meet the INSPIRE requirements for a place-name layer. The data also forms the underlying content for the Gazetteer for Scotland web pages: https://www.scottish-places.info/ In 2009 a workshop was run in conjunction with the Royal Commission on the Ancient and Historic Monuments of Scotland (RCAHMS) to examine the range of gazetteers in use in Scotland, together with a broad set of requirements. This identified a number of organisations which hold or maintain at least 15 different gazetteers that include geographical names for Scotland. The two most significant gazetteers were the Gazetteer for Scotland and the Ordnance Survey 1:50000 (OS 1:50K) product - which together form the basis for this dataset. The Gazetteer for Scotland is a descriptive gazetteer, with a modest number (22,000) of rich entries, including a textual description and rich feature-typing. At the time of creation, the OS 1:50K gazetteer had long been Ordnance Survey's only place-name gazetteer, used as part of numerous applications. It was decided that, for this new 'definitive' place name gazetteer, any named feature could/ should potentially be included, but it was accepted that the list will always be incomplete. This dataset could be used (and potentially linked with) other datasets like the Ordnance Survey Open Names, the One Scotland Gazetteer and the Historical Names gazetteer. The methodology for this data was a combination of automated and manual editing. Automated methods were used in feature classification and duplicate detection. Manual editing was required both to confirm or provide a feature classification, but also to improve the spatial referencing. Standards had to be adopted; for example water bodies were spatially located by a point which approximated its centre, while rivers were spatially located at their termination and other liner features by a random point along their length. The former gives a useful spatial reference, the latter in many cases does not. Quality checking suggests that 95% of points were located to 100m or better, and 5% located to 20m or better. More than 90% of features are classified correctly, on the basis of the evidence available. Copyrights and acknowledgments. The dataset is (c) Bruce M.

This is a GIS dataset containing spatial objects such as points lines and polygons. Lakes and large ponds in Wales digitised at 1:50,000. The primary objective of this project is to amalgamate Quattro spreadsheet data extracted from the OS 1:50,000 by the Ordnance Survey and the OS Lakes GIS layer available as a standard GIS dataset to produce a comprehensive GIS Welsh Lakes layer for use within NRW.

The data shows Ordnance Survey pond locations, where they match with the surveyed location of a priority habitat pond. The location and attributes of these priority habitat ponds does not currently exists for end users, ecologists, community groups and other stakeholders. The layer will be used to identify, conserve and enhance these features.OS Ponds (taken from the MasterMap Topography layer hydrology>static water) that have a matching pond survey (Clean Water for Wildlife of Priority Ponds) (see data within this folder for these layers) within their geometry, or within 30m of their edge. proximity was created (using NEAR tool) for points and then simplified (to remove 1 to many relationship) and joined to OS polygons using FID unique value. Unnecessary OS fields have been deleted.This data was created using data from Clean Water for Wildlife of Priority Ponds Clean Water for Wildlife - Freshwater Habitats Trust under a CC-BY licence with OS MasterMap data under the PSGA licence.It is published by Natural England under the Non-Commercial Government Licence due to the quantity of OS data contained within it.Full metadata can be viewed on data.gov.uk.

Each factory is coded to indicate whether it is on both or just one of the two 19th century series of Ordnance Survey London Town Plans. I have also tried to catagorize the factories. There are some other incomplete fields or fields used in earlier versions of this database.
