Ordnance Survey Maps - A Practical Guide
OS, particularly in its digital format, is present in most of our daily professional lives.
Whether using OS technology in our SatNav or GoogleMap applications, or drawing up a lease plan or submitting a property application to the Land Registry, we rely upon OS maps as a medium.
The Land Registry uses them as the base for its title plans and electricity, water and gas providers rely upon them to check wayleaves, ownership and access.
It is important to know what an OS map, digital or printed, actually provides; what are its accuracies, what are its limitations, where are the common pitfalls and how can a deeper knowledge of OS help your future operations?
