OS MasterMap - making all the difference

"The process of obtaining addresses is now very speedy. With OS MasterMap it takes five minutes to filter, clean and export an address file, with a complete mail merge of 500 addresses ready within an hour. We regularly save time on preparing address files, and updating our master map is simple."

Bader Al Schibani, CAD manager at London Borough Merton.

OS MasterMap® is a continually updated database containing a variety of information in four different product layers.

Address Layer 2 | Imagery Layer | Integrated Transport Network™ (ITN) Layer and Topography Layer

Between them they contain over 450 million geographic features found in the real world, from indidivual addresses to roads and buildings. Every feature within the OS MasterMap database has a unique common reference (a TOID®) which enables the layers to be used together, including the layer of your own information.

Existing OS MasterMap customers can order and manage updates through the online order service or your Agreement members area.
