As we release new enhancements into the OS NGD, we will update this page to provide you with a high-level summary of what's launched.
Buildings
New number of floors attribution added to Building features to identify the maximum number of occupiable floors at or above ground level within a residential or office building. Over 23.5 million office or residential buildings in Great Britain now have a number of floors value, and a total of nearly 47 million floors have been added to the OS NGD. Among other uses, the new attribution will provide emergency services with more information when responding to real-time incidents, such as a fire in a high-rise building, and will help support insurers to improve their risk profiling and underwriting.
Land Use – Enhanced land use attribution, increased coverage for Sites, and more Site Access Location points
New land use attribution will be provided for the OS NGD ‘Features’ Collections for Buildings, Land, Land Use, Structures, Transport and Water. The new attribution maps the OS land use classifications to the National Land Use Database (NLUD) schema and the land use information derived from OS Addressing. The new attribution helps to give more detail about what is contained within a Site – for example, the total number of addresses contained within a single Site and what number of those addresses are defined as commercial, residential, or other.
Greater coverage for land use Sites, particularly non-residential sites, with over 1.5 million Sites added to the OS NGD gradually over the last two years. This has brought the total number of Sites contained within the OS NGD to 26 million.
An additional 180 000 Site Access Location points have been added to the OS NGD. These features show where vehicles and / or pedestrians can access Sites and, among other uses, help the emergency services to identify the most efficient routes for reaching an incident.
Structures
Additional bridge interaction attribution added to Compound Structure features to identify the type of network (road, path, railway, canal, water or multiple) passing over and / or under bridges. Over 660 000 bridge interactions have been added to the OS NGD.
Buildings
New attribution provided for Buildings:
Building Age: The age of the main building in a site, created using Verisk data and OS data.
Construction Material: The primary construction material of the building, created using Verisk data and OS data.
Basement Presence: An indicator to show whether a basement or a self-contained basement flat are present at the building, created using Verisk data and OS data.
Building Description: A new description attribute to describe the nature of the building, derived from its use and relation to surrounding buildings, created using OS data.
More information on the buildings enhancements is available from the OS NGD Buildings pages in the 'Using OS NGD Data' section.
Land cover – Enhanced land cover attribution
Enhanced land cover attribution to ‘natural’ topographic area features across the OS NGD ‘Features’ Collections for Land, Structures, Transport and Water.
Improved consistency and accuracy for specific land features by reducing the minimum capture size criteria in rural and moorland geographies.
Mapping OS land cover classification to recognised habitat classification schemes (EUNIS and UK BAP Broad Habitats) in a new cross reference table.
Assigning a percentage cover value to topographic areas in a new cross reference table.
More information on the land cover enhancements is available from the OS NGD Land cover enhancements pages in the 'Using OS NGD Data' section.
Structures – Field Boundary
New Field Boundary Feature Type added to the Structure Features Collection to identify the location, nature and properties of a field boundary in rural and moorland areas.
Height and width values provided for vegetated field boundary features.
More information on this enhancement is available from the Field Boundary pages in the 'Using OS NGD Data' section.
Transport
New Tram On Road Feature Type added to the Transport Network Collection to locate where trams are present against the OS road network.
Tram track attribution added indicating the presence of tram tracks on a road. Supplied as new attribution against Road Link features.
More information on these enhancements is available from the OS NGD Transport pages in the 'Using OS NGD Data' section.
Geographical Names
New Named Road Junction Feature Type added to the OS NGD Named Features Collection, which provides enhanced names and the numbers of junctions. Includes both intersects without an official name or number and officially named or numbered junctions.
The OS NGD delivery roadmap (as of September 2024) can be seen in the following image; the roadmap details what was delivered in the March and September 2024 data enhancements releases, and what is planned for delivery in the upcoming March 2025 data enhancements release:
In the future, we plan to deliver over 25 data enhancements to the OS NGD. As we design and develop these data enhancements, more details will be added to the 'Future OS NGD Data Enhancements' page.
