What's New?

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.

2025 OS NGD enhancements

March 2025 – OS NGD data enhancements

Highlights of the OS NGD data enhancements released to customers in March 2025.

Highlights of the OS NGD data enhancements released to customers in March 2025:

Buildings

• New Building Access Location Feature Type added to the Building Features Collection. Building Access Location features identify access points to key public buildings for vehicles and pedestrians, enhancing urban planning, emergency response, and accessibility.

• New attribution provided for Buildings:

  • Roof Shape: Identifies the predominant geometric shape of a building's roof, aiding in visualisation and architectural analysis.

  • Roof Aspect: Provides information on the orientation of a roof, which is useful for solar energy planning and environmental studies.

  • Green Roof Presence: Indicates whether a building has a green roof, supporting sustainability and urban greening initiatives.

  • Solar Panel Presence: Shows if solar panels are installed on a building's roof, helping in renewable energy assessments and planning.

  • Roof Material: Details the type of predominant material used for a roof, which is important for construction, maintenance, and environmental impact studies.

  • Building Height: A comprehensive set of five attributes detailing the heights of various parts of a building, including both absolute and relative measurements. This enhancement supports urban planning and Emergency Services.

• These buildings enhancements aim to improve visualisation, urban development planning, emergency response, and sustainability initiatives. More information on the March 2025 buildings enhancements is available from the OS NGD Buildings pages in the 'Using OS NGD Data' section.

Examples of building features and attributes provided by the OS NGD Buildings and OS NGD Land Use Themes.

Geographical Names

• New Crowd Sourced Name Point Feature Type added to the OS NGD Named Features Collection, which includes names submitted by expert third parties via the Vernacular Names Tool in the OS Data Hub. Where possible, the crowd sourced names are linked to other OS NGD features, allowing the use of both official and colloquial names together.

Example of a Crowd Sourced Name Point feature being matched to existing OS NGD (Building Part and Address) features via its OSID (OS Identifier) and UPRN (Unique Property Reference Number). A background map has been included to provide context.

Land Use

• Three new types of site added to Land Use Sites descriptions: Beach, Military Training Area, and Wind Farm. Over 2 600 new sites have been added to the dataset for this enhancement (1 927 beaches, 90 Military Training Areas and 604 Wind Farms). These are sites that may not be spatially coincident with existing topographic areas (i.e. they may not align with topographic features like field boundaries), unlike other types of site. Beaches will include Site Access Locations with attribution that highlights the nearest public Road Node and the direct distance to that node from the access point on the edge of the beach feature. Military Training Areas and Wind Farms will not include Site Access Locations.

Example of a Land Use Site featuring a description of 'Beach' with Pedestrian and Vehicular Access Locations shown. Background maps are included for context.

• An Access Purpose attribute has been added to Site Access Location features for key public sites to identify what the Site Access Location is being used for (Primary Public, Public, Private, or Emergency). The new data will enhance and support situational awareness for emergency responses, hazard planning, and policing operations at key public sites; the data will also support travel modelling and make it easier to assess accessibility to services for the public.

Example of the four types of Access Purpose points within a football stadium for purposes of emergency response and evacuations. A background map has been included to provide context.

Structures

• The addition of nine different types of tunnel to the Compound Structure Feature Type. These were added to v2 of the schema on 28 March 2025 and v1 on 09 April 2025.

Transport

• New Street Light Feature Type added to the OS NGD Transport Features Collection to identify the location of pole-mounted street lights and provide a reference to the nearest Road Link or Path Link. This is the first consistent GB-wide dataset of street lights that is updated monthly and maintained to defined quality levels.
• New attribution supplied against the Road Link and Path Link Feature Types to indicate how well-lit they are. The new data will support the identification of safe routes for active travel use cases .

2024 OS NGD enhancements

September 2024 – OS NGD data enhancements

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.
