The OS MasterMap Address Layer provides precise coordinates for more than 27 million residential and commercial properties in Great Britain. It's the most accurate and up-to-date link between any property address and its location on the map.
The Address Layer originates from the Royal Mail's postcode address file (PAF®). OS use on-the-ground GPS survey, aerial imagery and various other techniques to establish precise coordinates for each address and match this to the property on the map - effectively joining up postal and topographic geography, creating a fixed link between the property and its address.
Addresses are subject to a high level of change from:
- the creation of a new property;
- property redevelopment; and
- house or street name changes.
This product provides a robust mechanism for users to track and manage these address changes relating to the actual property on the ground, and a continuity between a physical property (essentially unchanging) and the dynamics describing that property (changeable).
Address Layer is postal addresses only, if you require all addresses then please look at Address Layer 2.
