This sounds like what3words (<a href="http:&#x2F;&#x2F;what3words.com" rel="nofollow">http:&#x2F;&#x2F;what3words.com</a>), except they&#x27;re using unpronounceable alphanumeric addresses whereas what3words uses 3 actual words (and what3words is 3x3 meters instead of 5x5 meters). For example, for the coordinate that &quot;97.N7&quot; maps to, what3words calls &quot;narrow.career.puppets&quot;.
