Welcome to OS MasterMap

OS MasterMap – intelligent, location-based data

It's a bit like a map only smarter and more detailed and intuitive and analytical and up-to-date and information rich and ....actually, it's not very much like a map at all. In fact, it's one of the most technologically advanced and comprehensive analytical business tools of its generation. It's an intelligent, future-proofed database.

Critical executive decisions rely on what you know and the quality of the information you have to hand. Issues such as where to invest, how to cut costs whilst improving customer service or what premiums to charge for differing risk all include a geographical dimension. To ensure that your analysts brief you on the basis of the latest and most accurate information, equip them with OS MasterMap data.
