Thanks, Open Location Code looks like a great solution. https://plus.codes/6PJ4CWRW+H3 https://plus.codes/6PJ4CWRW+H3 for anyone who wants to play around with it. Although I must say that '6PJ4CWRW+H3' is still harder to communicate than horse.cow.sheep for example. That is the clever thing about what3words, the design of the addresses. What I like about Open Location Code is that adjacent squares have a similar name.
