There is something I remember seeing on HN a couple of years ago, and that was a website that, if I recall correctly, maps your address to unique tiles, and does this for different zoom levels.<p>Each tile gets a unique, relatively straightforward name/ID, and then you can map this name/ID to a specific lat/long (with the accuracy being determined by the zoom level you use)<p>I know there are tiling schemes used by Google Maps, Bing Maps, etc, but I seem to recall there was something unique in the approach of this website.<p>Unfortunately, my web search has been fruitless and I'm not able to find the relevant HN thread.<p>Do any of you remember this?
I can only think of <a href="http://what3words.com/" rel="nofollow">http://what3words.com/</a>, but they don't do zoom level encoding.
