The Ordnance Survey Kids' Adventure Book

Ordnance Survey, the national mapping service for Great Britain,<b> </b>makes it simple to enjoy an active outdoor life, live longer and get more out of every day. We inspire people to discover Great Britain's great outdoors with our iconic maps on paper, mobile and desktop. They are all designed to make the outdoors more enjoyable, accessible and safe. Launched in 2015, the OS Maps app puts digital versions of OS Explorer and OS Landranger maps for the whole of Great Britain in your pocket. We're also helping people explore new places and create lasting memories in Britain's cities and countryside with the new Secret Stories app. Our pioneering location expertise is recognised around the world and we recently launched OS Maps in Australia, with plans to roll out in other countries in the future.
