Transport Features

The OS NGD Transport Features Collection provides the most detailed topographic data available of the physical transport environment of Great Britain. The collection is made up of individual real-world topographic transport features, including roads, railway lines, tracks, and paths. Each feature is uniquely referenced and has attributes that record the feature’s lifecycle.

Collection applications

The OS NGD Transport Features Collection allows you to:

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

• Visualise the road, track and path network across Great Britain.

• Filter data using the Description attribute (for example, you can filter for pavements or central reservations).

• Perform statistical analysis.

• Visualise the rail network across Great Britain.

• Interpret the land cover adjacent to transport features.

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.

• Simplified attribute naming helps make names easier to understand.

• Persistent unique identifiers with lifecycle information.

• Cross-references make it easy for you to link data in this collection with data from other OS NGD collections.

• Linear geometry for the Road Line Feature Type and the Road Track Or Path Feature Type.

• Geometry available for every feature.

• Land use classification (for example, residential accommodation) provided for the Road Track Or Path Feature Type and Rail Feature Type to indicate the prominent use of the Site which contains the infrastructure.

• 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 Road Track Or Path features and Rail features within Lower Tier Local Authority areas to indicate which Lower Tier Local Authority boundary the feature lies within.
