The OS NGD Land Features Collection gives you access to the most current and comprehensive land cover data captured by Ordnance Survey as a standalone collection. It contains features which can be manmade (for example, tennis courts, residential gardens, construction sites) or natural land (for example, coniferous trees, cliffs, heath or rough grassland), but excludes features exclusively associated with buildings, structures, transport and water (the excluded features can be found in their respective OS NGD collections).

The collection is comprised of five feature types: Land, Land Point, Landform, Landform Line and Landform Point.

Collection applications

The OS NGD Land Features Collection allows you to:

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

• Perform powerful analytics, underpinned by unrivalled OS accuracy.

• Quickly identify land cover features of interest using the Description and Land Cover attribution, so you can perform tasks such as investigating flood absorption rates.

• Visualise the land cover make-up of Great Britain, particularly when used in combination with data from other collections, such as the OS NGD Building Features, Structure Features, Transport Features, and Water Features Collections.

• Calculate land area estimations to generate a statistical breakdown of land cover within your area of interest using the Geometry Area attribution.

• Easily query which areas of land are within an intertidal zone using the 'Is Tidal' attribute.

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.

• Comprehensive list of easy-to-understand land cover descriptions.

• Name attribution (if known) available for the Land Point, Landform and Landform Point Feature Types, so users can identify what specific land features are called.

• Land use classification (for example, residential accommodation) provided for the Land Feature Type to indicate the prominent use of the Site which contains the piece of land.

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

• An Office for National Statistics (ONS) Government Statistical Service (GSS) code is provided for Land features within Lower Tier Local Authority areas to indicate which Lower Tier Local Authority boundary the feature lies within.

Introduction to the theme

The OS OS NGD Land Theme contains point, line and polygon features depicting land cover information. These features can be manmade (for example, residential gardens, tennis courts, construction sites) or natural land (for example, heath or rough grassland, marsh, mixed trees). Features which are exclusively associated with buildings, structures, land use, transport, and water are excluded from the OS NGD Land Features Collection and can instead be found in their respective OS NGD features collections: the OS NGD , , , , and Collections.

The OS NGD Land Theme contains some land information data which can also be seen in the OS MasterMap Topography Layer, Sites Layer, and Greenspace Layer products. The data in the theme is the same as that provided by the aforementioned OS products, but it has been structured to be more analytical and consistent across the six OS NGD features collections, allowing you to easily select the specific features you require and delivering greater value to users. For example, in comparison to data in the three aforementioned OS products, the new OS NGD Land 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 a feature

• Detailed land use classification

• Detailed land cover classification

• Capture specification to give details about the geography of the area a feature resides in (that is, urban, rural, or moorland)

Data structure

The OS NGD Land Theme is made up of the OS NGD Land Features Collection, which in turn is comprised of five feature types: Land, Land Point, Landform, Landform Line, and Landform Point.

Unique identifiers

Two unique identifiers are provided with each feature within the OS NGD Land 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.

An area on the Earth's surface that has not otherwise been captured as a , , or feature and is too small to capture as a , for example, a coniferous tree or a non-coniferous tree.

Temporal filtering

The earliest date on which you can request a one-off snapshot of a date in the past for data in this feature type is 29 September 2022.

A description of the second level of an alternative land use classification as defined in the National Land Use Database schema.

• Data Schema Version: 3.0

An alternative land use classification that uses a code defined in the Address/BS7666 schema. Populated only where local authority address information lies within a Land Use Site that the feature also falls within. The value is derived by analysis of the attribution of Address information that falls within the extent of the smallest Land Use Site that the feature lies within. Where the address information within the extent of the Site contains differing primary level classifications, then no Address Code value is provided.

The description of the highest (least detailed) level of an alternative land use classification as defined in the Address/BS7666 schema. Populated only where local authority address information lies within a Land Use Site that the feature also falls within. The value is derived by analysis of the attribution of Address information that falls within the extent of the smallest Land Use Site that the feature lies within. Where the address information within the extent of the Site contains differing primary level classifications, then a value of ‘Mixed’ is applied.

The unique identifier of the Lower Tier Local Authority administrative area provided by the Office for National Statistics that the Topographic feature lies within. Where a Topographic area falls into more than one Lower Tier Local Authority, then it will be assigned to the Lower Tier Local Authority that the majority of its area lies within. Where a Topographic area falls outside any Lower Tier Local Authority (for example, an offshore feature), then no code will be provided.

Habitat Coverage Reference

A cross reference table mapping the OS land cover classification to habitat classification schemes – European Nature Information System (EUNIS) and UK Biodiversity Action Plan (BAP) Broad Habitats – and providing the percentage of each land cover classification within a topographic area, except Water features.
