'A gripping story about the personalities who initiated the mapping of Britain and their extraordinary skill and endurance' Max Hastings, Sunday Times The Ordnance Survey is a much beloved British institution, but in our modern map-obsessed world how much do we know about its curious origins and extraordinary challenges? Here at last is the remarkable story of the creation of the first complete, accurate, affordable map of the British Isles. What it reveals is a colourful and engrossing secret history of the Ordnance Survey and the obsessive and ambitious men who dreamt and delivered it.
