OS MasterMap Highways Network

Routing & Asset Management

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


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.

If you manage local highways, our asset management information lets your operations teams plan better in the office and avoid unnecessary site visits. By identifying points of special engineering difficulty and traffic sensitive streets, you can get the special permits you need in good time.

Put all the details your call centre operators need at their fingertips. When a water leak is reported, our asset management data lets them locate the property, street and nearest hydrant, assess the impact on nearby properties and decide if other assets are at risk.
