Transport Network

The OS National Geographic Database (NGD) Transport Network Collection provides a topologically structured link and node representation of Great Britain's road, ferry and urban path networks. This collection provides information on road classification; road and path function; primary routes; road node classification; names associated with the road and urban path networks; path surface type, and connectivity between the road network and the ferry and urban path networks.

Collection applications

The OS NGD Transport Network Collection allows you to:

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

• Identify the authority responsible for naming, numbering and maintaining a street.

• View ferry routes which start and end in Great Britain.

• Create statistics for evidence-based policy making, such as school transport allocation, funding distribution and meeting sustainable transport policies.

• Visualise the connectivity between the road network and urban path network.

• Examine the surface type, function and names associated with urban paths.

Key elements

• Monthly 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.

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

• Geometry available for every feature.

Coverage

Great Britain.

Default coordinate reference systems

British National Grid + ODN Height (EPSG: 7405) for most feature types in the collection; British National Grid (EPSG: 27700) for the Ferry Terminal, Path, Road, Road Junction, and Street Feature Types.

Temporal filtering

The earliest date on which you can request a one-off snapshot of a date in the past for data in this collection is noted at the top of the individual feature type pages.

Supply formats

GeoPackage, CSV (comma-separated values), GeoJSON or vector tiles (the latter format is only available for three feature types in the collection: Path, Path Link, and Road).

Supply mechanism

Accessed through the OS Data Hub via:

• OS Select+Build

• OS NGD API – Features

• OS NGD API – Tiles (only available for three feature types in the collection: Path, Path Link, and Road)

Using our data

• Included in the Public Sector Geospatial Agreement (PSGA) – therefore, it's free at point of use for Public Sector organisations.

• Available to OS Partners for commercial resell in your solutions.
