basically the system is a geolocator.
it uses 3 words to triangulate anywhere on this planet to within a 3 metre square.
More memorable than a zip code, or PostCode as used by UK, Canada et al.
Intended for simplicity and memorability. For a single location anyway.
And there are places in India, Africa etc that don't have a street name system.
And As I found out yesterday, a PostCode is fine for existing locations, but a new build (the guy has lived there a year) the internet and SatNavs are useless. What if it was a Folk Festival in a field,? LatLong coordinates suit you?
How many times do I tell people when I am on duty and am asked where PigsFoot Morris are ensconced in the mass of tents?
I say text the coords next time, but a verbal stuck.prune.fictional might be memorised.
Try the link above - & zoom in - it points to the entrance doorway of the sports pavilion used for late sessions and breakfast at the Upton Folk Festival 4th - 7th May 2018.

there are phone apps, and at the last count 14 languages (40,000 word lexicons congruent)
