OS MasterMap Highways Network brings together the best information from authoritative sources – the people who manage and understand the roads. It's a family of three products and you can try out each of them:
OS MasterMap® Highways Network is the most complete, detailed and accurate navigable road network dataset for Great Britain. It records the dimensions and accessibility of roads, making it ideal for planning streetworks.
Roads and Routing & Asset Management
OS MasterMap Highways Network - Routing & Asset Management gives you everything in Roads, plus information about who's responsible for managing different stretches of road. This helps infrastructure companies contact the right authority for permits to dig.
Along with OS path network geometry, you get the Local Highways Authorities’ name, numbering and maintenance responsibility information. This data helps you build pedestrian navigation apps, or manage utility works that affect foot and cycle paths.
