The OS MasterMap Highways Network product family provides an authoritative road and path network for Great Britain. The products are the result of collaboration between Ordnance Survey, GeoPlace and Improvement Service to bring together Ordnance Survey’s detailed road and path information, the National Street Gazetteer (NSG), the Trunk Road Street Gazetteer (TRSG) and the Scottish Street Gazetteer (SSG).
The Highways Network integrates the Unique Street Reference Number (USRN) from the gazetteers with the most detailed definitive geometry from Ordnance Survey. The OS MasterMap Highways Network was produced in partnership with GeoPlace and the Local Government Association, and as of March 2021, it contains data created and maintained by Scottish Local Government.
The OS MasterMap Highways Network family of products includes a road network, a path network, connectivity across British islands through a ferry network, plus routing and asset management information.
The product family includes three products:
OS MasterMap Highways Network – Roads
OS MasterMap Highways Network – Routing and Asset Management Information (RAMI)
OS MasterMap Highways Network – Paths
Key features of the products
OS MasterMap Highways Network products contain several features, including the following:
Unique Street Reference Number (USRN)
Road names from the naming and numbering authority
Department for Transport (DfT) road classifications
Road maintenance authority
Motorway junction to junction information
Vehicle height, weight, width and length restrictions information
Road reinstatement information
Connected network across Great Britain, including islands, through the Ferry Network
One of the key strengths of the products is the collection of street information at the local highway authority level. The benefit of this is that the data capture is at the earliest point of creation within a local highway authority and there is detailed local knowledge driven by statutory requirements.
