Natural Resources Wales (NRW) holds copies of Ordnance Survey (OS) basemaps for the whole of Wales, in paper and digital format. NRW obtain much of it's OS data, initially, as part of the Public Sector Mapping Agreement (PSMA) and from 2020 as part of the Public Sector Geospatial Agreement (PSGA), which is a collective agreement between OS and the government.

Great Britain's (England, Scotland, Wales) cities (e.g. London, Birmingham, Edinburgh) named and represented as point features with an indicative bounding box. This data is often used for geocoding, service delivery and statistical analysis. OS Cities Data is available in a number of Ordnance Survey (OS) products: OS Open Names (bounding box and point geometry), OS Names API, MasterMap Topography Layer (point geometry), Vector Map Local (point geometry) and Vector Map District (point geometry). Small-scale cartographic representations are also available in OS cartographic products. All data is collected by Ordnance Survey as part of their role as the National Mapping Agency of Great Britain.

The dataset comprises scanned images of maps and aerial photographs of the Falkland Islands. The original maps are printers films and final paper printed originals of Falkland Islands OS maps, compiled for the Falkland Islands Government and the Foreign and Commonwealth Office by the Overseas Directorate of the Ordnance Survey. The Falkland Islands Government retains copyright interest in the maps. There are no access or usage constraints for BGS staff for BGS purposes. The field slips of geological maps were compiled by BGS under contract to the Falkland Islands Government. Copyright remains with the Falkland Islands Government , but there are no access or usage constraints for BGS staff for BGS purposes. Access to both datasets are restricted to BGS staff.

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.

This dataset is wholly owned by Ordnance Survey (OS) and licenced for use by Natural Resources Wales (NRW) via an open data licence issued by OS. OS open data products (OS OpenData) are a set of free digital maps of Great Britain, available for anyone to use, for any purpose. The maps include data on roads, rivers and boundaries. This dataset includes layers derived from those available from OS.

Great Britain's (England, Scotland, Wales) towns named and represented as point features with an indicative bounding box. This data is often used for geocoding, service delivery and statistical analysis. OS Towns Data is available in a number of Ordnance Survey (OS) products: OS Open Names (bounding box and point geometry), OS Names API, MasterMap Topography Layer (point geometry), Vector Map Local (point geometry) and Vector Map District (point geometry). Small-scale cartographic representations are also available in OS cartographic products. All data is collected by Ordnance Survey as part of their role as the National Mapping Agency of Great Britain.

This layer of the map based index (GeoIndex) shows the location of available 1:10000 or 1:10560 series paper geological maps. Since the 1960s the standard large scale map for recording geological information has been the Ordnance Survey (OS) quarter sheet, covering a 5km by 5km area. The maps themselves are supplied in different formats depending on their age and the method of compliation or reproduction used. Only the latest and most up-to-date version is listed.

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.

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 index shows the availability of county series geological maps, 1:10560 scale. The maps themselves were produced on OS County Series sheets between approximately 1860 and 1960. The list indicates whether the map has been revised or re-surveyed and gives details of any later versions that have been produced. It is advisable to discuss your requirements before ordering or travelling to view these maps.

This layer of the map based index (GeoIndex) shows the availability of 1:50000 series paper geological maps. For England and Wales (and Northern Ireland), map sheets normally cover an area 30 km east-west and 20 km north-south; in Scotland the coverage is 20 km east-west and 30 km north-south. The 1:50 000 geological map grids are based on an early Ordnance Survey 1:63 360 (one inch to one mile) scale map grid and are not related to the current Ordnance Survey 1:50 000 map sheets. Maps are normally available in both flat and folded formats.

The OS Widgets extension for CKAN enhances data portals with map-based search and preview capabilities, primarily developed by Ordnance Survey for data.gov.uk. This extension provides widgets, an API for preview lists and spatial datastore for spatial data previews. It integrates mapping functionality into CKAN to allow users to discover and visualize geospatial datasets and to show a shopping basket preview list to give users an idea on what data to preview. Key Features: Map-Based Search Widget: Enables users to search for datasets based on geographic location, improving dataset discoverability in specific areas of interest. Map Preview Widget: Allows users to visualize geospatial datasets directly within CKAN, providing an immediate understanding of the data's spatial extent and content. Preview List API: Provides an API to store & manage a list of selected datasets for previewing, working as a "shopping basket" to keep a list of packages to preview. It supports adding to, removing from, and listing the packages available in the preview list. Spatial Database Integration: Supports the preview of data with geo-references (latitude/longitude coordinates, postcodes, etc.) through a spatial database (PostGIS). Spatial Ingester Wrapper: Includes a wrapper to call the Spatial Ingester, a Java tool that converts data (typically CSV/XLS) and stores it in a PostGIS database. This converted data can then be served in WFS format for display in the Map Preview tool. Configurable Server Settings: Enables customization of server URLs and API keys for the widgets, allowing configuration of the geoserver, gazetteer and libraries used in the widgets. Proxy Configuration Support: Provides guidance on configuring an Apache proxy to improve the performance of GeoServer WFS calls, ensuring quick retrieval of boundary information. Technical Integration: The extension integrates with CKAN through plugins (ossearch, ospreview, oswfsserver) that are enabled in the CKAN configuration file. Configuration involves adding plugin names to the ckan.plugins setting and adjusting server URLs, spatial database connection details, and API keys according to the specific environment, ensuring seamless integration with existing CKAN deployments. In addition to the PostGIS dependency that has to be created, it is also dependent on other external libraries such as, Jquery, underscore, backbone, etc. Benefits & Impact: Enhanced Data Discovery: Map-based search significantly improves the discovery of geospatial datasets within CKAN, allowing users to easily find data relevant to their geographic area of interest. Improved Data Understanding: Map previews provide immediate visual context for geospatial datasets, leading to a better understanding of the data's spatial characteristics.

As of the July 2021 basemap update, the raster basemaps (OS Open Carto, Background, Greyscale and Greyscale Labels) have now entered Mature Support. These four services will no longer be updated but will remain available to use for the foreseeable future. We encourage users to switch to the new GB Vector Basemaps. Read more in our blog.The OS Open 'Background' map service is designed to be used as background mapping providing a seamless map view from small to large scales with a consistent cartographic representation. The sources of data are Ordnance Survey Vector Map District data for small and mid-scales and Open Map Local for larger scales.The currency of the data is; Vector Map District - 05/2021 Open Map Local - 04/2021The coverage of the map service is GB. The map projection is British National Grid. The service is appropriate for viewing down to a scale of approximately 1:5,000. Updated: 17/07/2021

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.

This contains records taken from the Archaeological Survey of Ireland (ASI) dataset, updated in 2018 and published from the National Monuments Service Sites and Monuments Record. The ASI has focused on recording monuments dating from before AD 1700, along with more recent sites selected according to their interest or merit. Locations of monuments within 2km of the coastline were extracted from the ASI dataset by Land Use Consultants (LUC). The records were downloaded from the data source URL in CSV format. The table included latitude/longitude locations for each record. The table was converted into ESRI shapefile and the records within the 2km coastal zone were extracted. Since its inception in 1963, the Archaeological Survey of Ireland (ASI) has focused on recording monuments dating from before AD 1700, along with more recent sites selected according to their interest or merit. A Sites and Monuments Record (SMR) was issued for all counties in the State between 1984 and 1992. The SMR is a manual containing a numbered list of all certain and possible monuments accompanied by 6-inch Ordnance Survey maps (at a reduced scale). An Urban Archaeology Survey was completed in 1995 and contained reports on historic towns dating to before AD 1700 with a view to delineating zones of archaeological potential. Both the SMR and the Urban Archaeological Survey reports were issued to all planning authorities. The SMR formed the basis for issuing the Record of Monuments and Places (RMP) - the statutory list of recorded monuments established under Section 12 of the National Monuments (Amendment) Act 1994. The RMP was issued for each county between 1995 and 1998 in a similar format to the existing SMR. However, the RMP differs from the earlier lists in that, as defined in the Act, only monuments with known locations or places where there are believed to be monuments are included. The large archive and supporting database are managed by the National Monuments Service and the records are continually updated and supplemented as additional monuments are discovered. Please note that the centre point of each record is not indicative of the geographic extent of the monument. The existing point centroids were digitised relative to the OSI 6-inch mapping and the move from this older IG-referenced series to the larger-scale ITM mapping will necessitate revisions. The accuracy of the derived ITM co-ordinates is limited to the OS 6-inch scale and errors may ensue should the user apply the co-ordinates to larger scale maps. Records that do not refer to 'monuments' are designated 'Redundant record' and are retained in the archive as they may relate to features that were once considered to be monuments but which on investigation proved otherwise. Redundant records may also refer to duplicate records or errors in the data structure of the Archaeological Survey of Ireland.

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.

This dataset contains polylines depicting non-woodland linear tree and shrub features in Cornwall and much of Devon, derived from lidar data collected by the Tellus South West project. Data from a lidar (light detection and ranging) survey of South West England was used with existing open source GIS datasets to map non-woodland linear features consisting of woody vegetation. The output dataset is the product of several steps of filtering and masking the lidar data using GIS landscape feature datasets available from the Tellus South West project (digital terrain model (DTM) and digital surface model (DSM)), the Ordnance Survey (OS VectorMap District and OpenMap Local, to remove buildings) and the Forestry Commission (Forestry Commission National Forest Inventory Great Britain 2015, to remove woodland parcels). The dataset was tiled as 20 x 20 km shapefiles, coded by the bottom-left 10 km hectad name. Ground-truthing suggests an accuracy of 73.2% for hedgerow height classes.
