UK boundary dataset corresponding to the geography of the ONS UACNTY09 coding frame. The dataset consists of 143 features corresponding to a standard GB county/unitary authority geography with the following exceptions. Orkney, Shetland and the Western Isles are included as a single feature; The Isles of Scilly are not included; Greater London is split into 2 Inner and Outer features corresponding to the super geographies within which the Inner and Outer London boroughs fall; Northern Ireland is provided as a single feature and is shown alongside the rest of GB in British National Grid. The GB portions of this dataset was derived from Ordnance Survey Boundary-Line data available as part of the Ordnance Survey OpenData initiative. The full terms and conditions of use of Ordnance Survey OpenData which apply to this dataset may be viewed at the following location: http://www.ordnancesurvey.co.uk/opendata/docs/os-opendata-licence.pdf.

This dataset is refreshed on a weekly basis from the datasets the team works on daily.Last update date: 29 August 2025.National Highways Operational Highway Boundary (RedLine) maps out the land belonging to the highway for the whole Strategic Road Network (SRN). It comprises two layers; one being the an outline and another showing the registration status / category of land of land that makes up the boundary. Due to the process involved in creating junctions with local highway authority (LHA) roads, land in this dataset may represent LHA highway (owned by National Highways but the responsibility of the LHA to maintain). Surplus land or land held for future projects does not form part of this dataset.The highway boundary is derived from:Ordnance Survey Mastermap Topography,HM Land Registry National Polygon Service (National Highway titles only), andplots researched and digitised during the course of the RedLine Boundary Project.The boundary is split into categories describing the decisions made for particular plots of land. These categories are as follows:Auto-RedLine category is for plots created from an automated process using Ordnance Survey MasterMap Topography as a base. Land is not registered under National Highways' name. For example, but not limited to, unregistered ‘ancient’ highway vested in Highways England, or bridge carrying highways over a rail line.NH Title within RedLine category is for plots created from Land Registry Cadastral parcels whose proprietor is National Highways or a predecessor. Land in this category is within the highway boundary (audited) or meets a certain threshold by the algorithm.NH Title outside RedLine category is for plots created in the same way as above but these areas are thought to be outside the highway boundary. Where the Confidence is Low, land in this category is yet to be audited. Where the Confidence is High, land in this category has been reviewed and audited as outside our operational boundary.National Highways (Technician) Data category is for plots created by National Highways, digitised land parcels relating to highway land that is not registered, not yet registered or un-registerable.Road in Tunnel category, created using tunnel outlines from Ordnance Survey MasterMap Topography data. These represent tunnels on Highways England’s network. Land is not registered under National Highways' name, but land above the tunnel may be in National Highways’ title. Please refer to the definitive land ownership records held at HM Land Registry.The process attribute details how the decision was made for the particular plot of land. These are as follows:Automated category denotes data produced by an automated process. These areas are yet to be audited by the company.Audited category denotes data that has been audited by the company.Technician Data (Awaiting Audit) category denotes data that was created by National Highways but is yet to be audited and confirmed as final.The confidence attribute details how confident you can be in the decision. This attribute is derived from both the decisions made during the building of the underlying automated dataset as well as whether the section has been researched and/or audited by National Highways staff. These are as follows:High category denotes land that has a high probability of being within the RedLine boundary. These areas typically are audited or are features that are close to or on the highway.Moderate category denotes land that is likely to be within the highway boundary but is subject to change once the area has been audited.Low category denotes land that is less likely to be within the highway boundary. These plots typically represent Highways England registered land that the automated process has marked as outside the highway boundary.Please note that this dataset is indicative only. For queries about this dataset please contact the GIS and Research Team.

Ward boundaries for all London boroughs suitable for use in i-Trees Canopy tool. Based on Ordnance Survey Boundary-Line data available from the OpenData website. Data has been converted to latitude/longitude values (WGS84 geographic coordinate system) and saved in shapefile format, suitable for use on the i-Trees website. The i-Trees tool offers a quick and easy way to produce a statistically valid estimate of land cover types e.g. tree cover, using aerial images available in Google Maps. All that is required is an internet connection and a shapefile which defines your study area. We recommend using the boundary of your ward as a study area and this can be obtained by downloading the zip file for your Borough below. Each zip file contains individual shapefiles for every ward in that area. Each shapefile requires four different files in order to work correctly so please ensure these are all extracted from the zip file before trying to upload on the i-Trees website. For example the shapefile for Brockley ward in Lewisham consists of the following files: -Lewisham_Brockley.dbf -Lewisham_Brockley.prj -Lewisham_Brockley.shp -Lewisham_Brockley.shx

An update for 30x30 project. These layer contains all terrestrial, protected area sites that contribute toward Scotland's commitment to protect or conserve 30% of land by 2030. This includes SSSIs, SACs, SPAs, Ramsars, and NNRs. These data have been clipped to OS BoundaryLine and is not dissolved so it can still be identified which areas are designated as what protected area types. Column “PA_Type” in the attribute table can be used for this.This data differs to that which Scotland reports 30x30 progress to, which uses MLWS. Purely geological SSSIs were not included. The protected areas are up to date as of 31/05/2024.

National boundary lines between England - Scotland and England - Wales.

The current counties of England are defined by the ceremonial counties, a collective name for the county areas to which are appointed a Lord Lieutenant. The office of Lord Lieutenant was created in the reign of Henry VIII. The Lord Lieutenant is the chief officer of the county and representative of the Crown. Whenever the Queen visits an area she will be accompanied by the Lord Lieutenant of that area. Legally the ceremonial counties are defined by the Lieutenancies Act 1997 as ‘Counties and areas for the purposes of the lieutenancies in Great Britain’ with reference to the areas used for local government.

This data shows the old ONS codes and new GSS codes for Great Britain. This should make it easier to map data which has one of these two standard codes. The old ONS codes are no longer shipped with OS Open boundary line data so having a mapping between the old-new might be very useful. The data is available as a shapefile showing GB districts from the 2012 Boundary line data. This dataset was made from OS Opendata Boundary line http://www.ordnancesurvey.co.uk/oswebsite/products/boundary-line/index.html and a table on wikipedia http://en.wikipedia.org/wiki/ONS_coding_system.
