Chapter 1.5 Address Layer Overview The Address Layer in OS MasterMap provides the location of approximately 26 million residential and commercial postal addresses in Great Britain. The Address Layer originates from Royal Mail's PAF. Ordnance Survey matches PAF addresses to their real-world location and represents this by coordinate values. When the address can be matched to a building feature then a reference! between the building and the address is created. Information,Figure 1.5.1 Example of the Addr esnots Layer u sejustd with the T oapog ramapphy Layer ! Information about part of a RoadLink specific to a given direction of travel RRI features that apply to a specific direction of travel along to a portion of a single RoadLink are captured as PartialRoadRouteInformation features.
