<br /> Reading about what it is, it is just a lookup between some random three words and a location. We don't map addr:latlon=51.34,3.45 in OSM, why would we map addr:w3w? Especially since it is just a lookup. The way I see it, this is something you would add to nominatim.</div>

<div class="pre" style="margin: 0; padding: 0; font-family: monospace"><span style="white-space: nowrap;">I see it as a kind of alternative postcode. You advertise your own location as a w3w, and anyone who needs to get there does a lookup through</span></div>

The problem with latitude and longitude coordinates is that if you make a mistake when writing them down you will be completely lost. But with our system similar sounding words are located very far apart so people don't get lost if you hear it wrong."<br /> First, making a mistake in a lat/lon coordinate does not by definition mean you are completely lost. It is when you make a mistake in significant digits (add one degree to the latitude and you're way off) but it isn't when you make a mistake in the non-significant digits (the difference between 51.3456247 and 51.3456248 is mere centimeters).<br /> Secondly, if you write a similar sounding word wrong, you are completely off. I mean, they specificaly say "similar sounding words are located very far apart".<br /> So if someone tells you nice.place.here and you use nice.place.hear, you are by definition not near your intended location.</div>

<div class="pre" style="margin: 0; padding: 0; font-family: monospace">As I understand it, they have avoided homophones like your example. The idea of placing similar-sounding words far apart geographically is that you would be instantly alerted to an error. If you expect a location in North London and it translates to Peru, a bell would ring an you would double-check it. But if you the location you hear translates to one 1km from what was intended, you might be going round in circles for hours trying to find it.</div>
