Mapcode – A short address for any location on Earth
I'm a little confused about what this replaces, but it's definitely not postcodes.* Postcodes have a specific meaning: they're both a geographical area and a mail delivery zone (at least in the US). Replacing one short code with another, which requires a different and less reliable third-party service to correctly decode, doesn't seem like a good idea.* Latitudes and longitudes are unambiguous, well-understood, and don't require a third-party service to be online in order to correctly decode. So it doesn't seem like this can replace latitudes/longitudes, unless we're talking about shortening their representation.* Broadly speaking, while addresses have a lot of problems, they're unambiguous with human context. So this doesn't seem like it really replace addresses either.* For things like a loose description that might not be associated with a single point (e.g. "Central Park"), I could see mapcodes being useful -- you can provide the precise boundaries of the park, where it's located, associate metadata with the mapcode like what hours the park is open, etc. That might be very helpful.Also, won't there be multiple mapcodes for a single spot and won't that require cross-association of the respective metadata? For example, consider that Central Park is also in Manhattan, also part of NYC, also in Midtown in NYC, etc.I guess that's not necessarily a problem, but it could lead to a lot of expensive processing for frequently updated locations/boundaries (e.g. a beach, a suburban development in progress, etc.).
