OS MasterMap Highways Network - Routing and Asset Management

Great Britain's most complete, detailed and accurate road network dataset.


Routing and asset management

For vehicle routing and navigation software providers, this data gives you all you need to get your users safely to their destinations: turn, height, weight and width restrictions – and even bollards and traffic calming.

Improved planning

Our asset management information allows highways teams to improve planning schemes in the office, avoiding unnecessary site visits. It can also identify potentially difficult locations, so you can organise required permits in good time.

One instant view

All the details at your fingertips. If a water leak is reported, use the data to find the property, street and nearest hydrant and assess impact on nearby properties, while determining the risk to other assets.

Knowing turn information

Go beyond just the restrictions with detailed information about narrow roads and pinch points. Join up your organisation's common reference to roads and help make informed decisions around the road quickly and effectively.

Comprehensive and authoritative
