Specification changes

There have been small enhancements to the OS MasterMap Highways Network. This section will outline the main changes to the Road Network product. For changes to the Routing and Asset Management Information product, please see the Routing and Asset Management Information Technical Specification.

Features

• RoadJunction feature has been populated.

• RoadLink and RoadNode ‘z’ values have been enhanced to reduce discrepancies when the road passes over a structure, for example, a bridge.

Code lists, data types and enumerations

• The “OperationalState” attribute on the Street features has introduced a new value, “Addressing Only”, into the “OperationalStateValue” codelist.

• Corrected wrong multiplicity value for minimum width attribute within the “RoadWidthType” Data Type. This had the incorrect value of ‘1’ this has been corrected to ‘0..1’.
