Actually, Salt Lake City in Utah is sort of vaguely like that, though with street numbers (in the usual units of 100 per block) rather than latitude and longitude per se.
The addresses are things like "250W 500S, Salt Lake City" -- which is going to be on the fifth street north of the Temple (and marked as 500S on the street signs), two and a half blocks west of the north-south street that's centered on the Temple (which is Main street, not W. Temple Street. W. Temple Street is what would be 100W if it weren't named).
I'm not sure what the history is on canonical orderings of the two parts of the address. Currently it seems to be usually the one that's the "street number" followed by the one that's the "street name", but I'm not sure if that's a result of auto-regularization by systems that assume such a thing, or if it's historical.
And sometimes an address that references a box number is both the "where they get mail" and the "where they live" address.
I grew up at the address of "Route 1, Box 78, City, State ZIP". That was the rural mail delivery route, but it was the only actual address there was, unless you wanted "last house on county road 601 before you go over the top of the mountain" sorts of things. (The mailbox in question was on a post at the end of our driveway, and said "78" on it.) UPS and FedEx would deliver there, though sometimes we had to point out to a new UPS driver that no, we weren't box 79; they were two miles away on the next bit of the mail route.
This also points out the changeability of addresses. Before I was old enough to remember, it was Route 1 Box 150A. And then ten or fifteen years ago, they went through and named all the streets and numbered all the houses, so it became "420 Streetname, City, State ZIP". The postman still knew that when my grandfather sent mail to Box 150A it should come to us, though.
My current house is a duplex. The normal scheme would be something like "100 Streetname, unit A" or something, but somehow we ended up with "100A Streetname" instead. For added confusion, the actual doors aren't labeled, just the mailboxes.
