Looking up some places on streetmap.co.uk last week (someone wanted to know which WAB square I was in at some point) I came across a reference to what3words…
Looking into it further, I ended up at https://what3words.com/about/
Complete with an app (at least for android) it can apparently pinpoint your position to a 3x3m square (although it did think I was sitting in the middle of my driveway earlier, but that could be GPS not working through my roof… )
This could be useful, maybe, in emergencies, for example, one of my daughters friends slipped on the Wrekin, and unfortunately broke her leg. Boyfriend called for an ambulance, and they asked for a postcode… “um, we’re on a path up the Wrekin, no idea what the postcode is…”
With what3words on their phone, they could have told the emergency people “pines.gangway.shoulders” which would pinpoint them to https://map.what3words.com/pines.gangway.shoulders and hopefully get the emergency people there faster.
Of course, we could then have a ‘Worked All What3words’ award, although that may take a while to complete!
GPS wise, apparently Navmii GPS World (probably others too) support what3words too, I must give it a try.
