OS MasterMap ITN and GO Loader

Unlock the power of the OS MasterMap Integrated Transport Network using the new ITN tool for GO Loader.

The Integrated Transport Network within OS MasterMap is a multi modal transport network designed as a replacement for OSCAR. It currently features two themes:

Road Network: Describes the road network throughout Great Britain, this includes all public roads and a large majority of private roads. The theme also has details of ferry links which vehicles may use to move from one part of the network to another.

Road Routing Information (RRI): Describes the various restrictions that may be found on any part of the road network. The theme identifies limitations as no turns, one way streets, height restrictions, and date / time / vehicle qualifiers.

The ITN Tool integrates with GO Loader to further process the ITN Road Network and RRI themes, opening their feature rich non-spatial attribution to all mainstream GIS applications including ESRI, MapInfo, Autodesk and Intergraph.

Implementing ITN using the GO Loader ITN Tool means customers are not just being told there is a restriction somewhere around a road junction. Accurate information on the restriction itself can now be displayed, supplying comprehensive and detailed alternative routing paths to help users around any potential obstacles. With the GO Loader ITN tool customers get the full benefit of ITN from directly within their chosen GIS packages.
