Just though i'd share this mapping/direction website i've come across.
What3Words have mapped the world into 3m x 3m grids which they allocate 3 words to.
They also have apps which can link to current mapping programs on your phone to give you directions to locations live.
Now I love getting lost in the lanes in Chorio on Symi but I can really see a use for this to pinpoint a location of a particular Taverna or great view.
You could also use to locate turning points in a walking route etc..
Try this link to see where the Rainbow bar is located. (frequented by many on here) Clicking on the OpenStreetmap to give quite a good map but a little outdated.

In my blog later in June I can link to the Tavernas visited or a great view.
It will not be something for all but I like it!
