Arthur Sheriff has come across this clever new way to identify locations.  Very useful if one unfortunately gets lost on a moor or even worse, has an accident on a remote river bank.

Much simpler to find and work with than grid references, What3words is a system which has mapped the world into 3m squares, and assigned each one an ID based on 3 random words.

The system relies upon the use of an app, which can be found here: https://apps.apple.com/gb/app/what3words/id657878530

Here is an interesting news article about the successes of the system: https://www.bbc.co.uk/news/technology-47705912
