Ideal for route planning or to manage your resources, it consists of three elements: Road Network (road geometry), Road Routing Information (routing information for drivers on mandatory and banned turns and other restrictions) and Urban Paths (man-made path geometry in urban areas).
The data are supplied in Geography Markup Language file format. The network is a link-and-node based network containing details about each link such as: the class of road (A-road, B-road, etc.) nature of road (Single carriageway, dual carriageway, roundabout, etc.), road names and road routing information (RRI) (banned turns, one-way streets etc.).
The main benefits of this product are that all 545,000 km of roads in Great Britain are accurately mapped in a consistent logical link and node network; that it contains 1.7 million road routing and information features; its currency (all road changes are captured within 6 months); the Urban Paths Theme complements ITN’s road information by adding path networks in all urban areas and it is designed to relate to other OS MasterMap layers.
ITN is referenced in the CycleNetXChange schema.
ITN forms a key element in the UK Digital National Framework (DNF).
