The OS NGD Land Use Features Collection gives you access to the most current and comprehensive land use sites and site access data captured by Ordnance Survey.

Collection applications

The OS NGD Land Use Features Collection allows you to:

• Ensure your land use data is always completely up to date, with up to daily updates.

• Access all our land use sites and access locations data from one place.

• Visualise and analyse data based on the extent of areas with different types of land use, including amongst others, residential, education, greenspaces, hospitals, and transport hubs.

• Quickly interpret the land use which is happening at a given site, using the description or land use attribute value (such as private residential, primary school, golf course).

• Analyse the number and location of sites with a given land use across areas or regions (such as locating all the schools in a county).

• Understand the location of access points into major sites (such as train stations, schools, and public parks) and how these sites are accessed from the road network.

Key elements

• Up to daily updates to data.

• Plug and play – the data is simple and quick to implement as you don't need to pre-process it before you use it.

• Rich attribution ensures the data is straightforward to navigate and query.

• Persistent unique identifiers with lifecycle information.

• Includes Sites for a wide range of land use types all in one dataset.

• Consistent classifications.

• Name attribution for non-residential sites (if known).

• Millions of new sites, including sites representing areas with residential land use.

• Further sites for non-residential land use to be added over time.

• Site access location and routing points with links to OS NGD transport networks.

• National land use standards used to provide universal insights for human activity (NLUD classification and BS7666 national addressing classification).

Introduction to the theme

The OS NGD Land Use Theme contains features which are geographical representations of areas identified as having a specific purpose (such as schools, universities, and caravan parks), as well as information about access to such areas.

In comparison with OS data from our traditional Download products, the OS NGD Land Use Theme data has been enriched with additional attribution, including the following:

• Geometry change metadata

• A Description attribute to provide a one-word or simple phrase description of the feature

• Hierarchical land use classification

Data structure

The OS NGD Land Use Theme is made up of the OS NGD Land Use Features Collection, which in turn is comprised of the Site and Site Access Location Feature Types.

Unique identifiers

Two unique identifiers are provided with each feature within the OS NGD Land Use Theme:

• OSID (Ordnance Survey Identifier): The primary identifier and unique key for this theme.

• TOID (Topographic Identifier): An additional secondary identifier which can aid further data linking. TOIDs are an optional attribute and therefore will not always be provided with every feature.

What are land use sites?

A land use site is a geographic representation of an area that can be identified as being used for a particular purpose, for example, a school, shopping centre, or private residence. These are captured by OS primarily through manual or automated interpretation from aerial imagery. Sites seek to define the extent of the activity, and while this may be similar to or the same as the ownership information provided by HM Land Registry (HMLR) or Registers of Scotland (RoS), it should not be regarded as representing ownership. Sites do not indicate the definitive or legal extent, but rather the extent of usage or function. Often, the line of a legal boundary will coincide with a physical feature, such as a wall or a fence, but it is important to remember that the legal boundary is not the same as the physical feature.

The location on the road network which provides entry or exit into a site for vehicles and / or pedestrians, represented as a point geometry.

Feature type attributes

The following sub-sections provide details about the attributes included with this feature type, their data types in the different output formats, and other important metadata about them.

osid

Primary identifier for the feature. The OSID is a Globally Unique Identifier (GUID) and requires no centralised authority to ensure uniqueness. Note that the same OSID can occur in more than one feature type when a single feature is represented multiple times in the OS NGD.
