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.

New for April 2013-  Sites Layer

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