I honestly don't understand why anyone would use Geohash? Because it's one number instead of 2?<p>The short definition is "A geohash is a convenient way of expressing a location (anywhere in the world) using a short alphanumeric string, with greater precision obtained with longer strings."<p>Here's another way to "use a short alphanumeric string" and "get greater precision with longer strings": "37,122", "37.7,122.4", "37.77,122.41", "37.774,122.419"<p>That seems so simple and universal and has been a standard since before our great grandparents were born, time to disrupt it to save a couple of bytes?
