Sounds like they need to prune the word list and/or group together possible mispronunciations, misspellings and misreadings. If "correct horse battery" is a location, then "correct hose battery" and "correct house battery" need to be synonyms of the same location, not alternate locations. Either that or remove horse, hose and house from the word list entirely.

Google "Plus Codes" are being used in India - especially in underserved communities like slums. https://www.addressingtheunaddressed.org/ . If you want to use this tech + operations expertise in other geographies...just reach out to them. They intend to share their knowhow and expertise. https://www.youtube.com/watch?v=Hd3gGspgVGs Also from what i understand, after the success in Kolkata, this was then used in Native…

So few people know about this. I actually wish it was used a lot more.

It uses Latin alphabet. Most countries with Latin alphabet have an address system already in place for centuries.

The examples given here seem like the best case of it going wrong, they’re in a different country and UK rescuers know within seconds that they’re wrong. I think this case further down is much more concerning: > He found that the algorithm behind W3W often gave similar-sounding words and plural versions of words for locations in close proximity, which could cause confusion. > So, for example, circle.goal.leader and c…

It's literally in the article: "So, for example, circle.goal.leader and circle.goal.leaders are less than 1.2 miles (2km) apart along the River Thames." That's potentially catastrophic, without an easy way to spot the mistake.

That's the exact example used in the comment you're replying to...?

Terrible: based on a single language, proprietary, IP owners being assholes, creates problems to the user case it was supposedly designed for, doesn't feature distance computing algorithms, takes even more space in a DB cell than latlong, I can go on for days. Use numbers.

There are really are issues with such a system and you listed some of them, but your recommendation makes me feel like you didn't read beyond the headline. They need a way to transfer location data by the word of mouth, which is extremely difficult when you're using numbers. With longer numbers, such as a comparatively precise location, you have a high risk of errors on both ends, so searching for a solution makes ab…

That doesn't sound correct. Numbers are universal, easier to remember, and less ambiguous than three English words. I don't see how it's more error prone to use numbers based systems, which many organisations and communities have been using for decades. And also considering the length of the three words which is roughly the same.

I don't envy the team. It's a great idea but falls short once it leaves the lab. Everything gets really dirty in the real world especially during high stress or emergencies. Moving to four words could really help remove the need for plural and words that sound similar. Accents really do make things tough.

It's not a great idea it's a stupid idea.

Unless I was asleep replying(there is a 5% chance of that), I'm pretty sure their comment didn't say that at the time.

Though What 3 Words requires you to download a custom app & for the emergency services to use a back-end for the same app when handling incoming calls — if we're doing that, could we not just have a simple app that checks your GPS and then dials 999 with your lat/lng added to the phone number? My bank get me to key in my sort code & account number while using telephone banking. If we did the same here, we could get t…

In New Zealand if you call the emergency number 111, the operator can automatically request the location of the device from the telco (with no opt out) if they belive there is a serious emergency and the location is not communicated. There is also some standardised way for the mobile phone to automatically send GPS coordinates to emergency numbers.
