Outside of the nonsensical urban tesseract known as the West Village, Manhattan’s street grid system is famously simple: Avenues run north/south(ish), streets run east/west. A phrase like “5th Avenue and 33rd Street” isn’t just an arbitrary address, it’s a cartesian coordinate that can actually help you get to where you’re going as well as recognize when you’ve gotten there. With a system this easy, it’s hard not to wish the whole world used it. Harold Cooper’s brilliant Google Maps mashup, ExtendNY, gives you an idea of what such a world would look like: Punch in any address or location on the globe, and it tells you what its NYC-style address is.
