One of the things that intrigues me about Google's Plus Code addressing system is how it converts longitude and lattitude into "area block intervals" -- the first four digits represent a large area, the next four + three represent a small area, and if you know the large area, you can specify only the latter seven, or if the area is big enough, you could ignore the last three digits after +, or if you're talking about a ranch or a campground, you could even specify just the last three digits. The first four are analogous to "year", the second four to "month", and the last three to "day". This can even be continued into smaller and smaller intervals, just as we can divide a "day" into "hours" and "minutes" and "seconds" and so forth, we can specify smaller and smaller areas with plus codes.
