Is anyone getting to grips with the new OS Highways dataset? It has been available to PSMA members for a year now and will replace the ITN dataset by 2019. At the moment, both are available and share the same geometry. The Department for Transport has funded this new dataset to incorporate the most complete, detailed and accurate navigable road network dataset for Great Britain.
There are three "flavours" of OS Highways: 1. Roads, 2. Roads and Routing and Asset Management, and 3. Paths. Like ITN, the data is supplied as relationship tables but there is a lot, lot more of it. Rather than supplying "chunks" of data (or tiles), the data is available by Govt region or whole country.
OS have made available a FME Workbench to aid translation from the GML files - if you have FME software. Otherwise, Routeware have produced a translator to produce the data in a format suitable for use with RouteFinder and routing purposes. BY Design are next with producing a translator to MapInfo format tables.
