Stéphane,

There will be shortly, will reply to this thread in due course. At the moment we’re working on extending relationships with community members and government from our pilot in June last year to scale regionally.

Best,

Mark

We will do this in such a way and with suitable licences and documentation to ensure that any and all users of what3words, whether they are individuals, businesses, charitable organisations, aid agencies, governments or anyone else can continue to rely on the what3words system.

The benefit being that you can now communicate that location in a human friendly and rapid way. You can collect the 3 word location for the front of the tent or the centroid (if the coordinates have already been collected  you can use the batch conversion tool - http://developer.what3words.com/batch-conversion-tool/ <http://developer.what3words.com/batch-conversion-tool/>).

A lot of the time when the similar sounding addresses are near enough to each other it can be very confusing and often results in huge delays whilst the user works out what has gone wrong and what the right address actually is.

My experience in rural Tanzania is that they don't have that experience. We've been integrating what3words so people will be able phone or text location. ID numbers on water points just washed away/eroded. what3words works even under partial degradation, then it can be error corrected unlike a postcode where every digit is relevant.
