It must be frustrating for an author to write an article but then to have the editor apply a click-baity title that makes no sense.
Of course Mapcodes can't replace GPS, they tell you where a thing is in relation to other things but not where you are. I know that the yoghurt is near the milk but that doesn't help if I don't know where I am in the shop. I have to ask someone to translate my current position into the same locational namespace and then start to plan a route.
Perhaps they will become useful for stating the location of a destination bit under the covers they will always be translated to a linear coordinate system for navigation.
Reinvention of DNS. Speaking of money for imaginary rented identifiers, there is/was a LOC type for DNS. So meet me at pizzahut.com isn't going to work with thousands of locations (but... anycast?) although meet me at momandpopsfamilydeli.com will work.
If every Pizza Hut had its own DNS server (kinda expensive and impractical), and each location was guaranteed to respond fastest based on your location (which it won't today), then it would work.
Like if you were at the Combination Pizza Hut and Taco Bell on Jamaica Avenue, and you're trying to meet up with your friend who's at the Combination Pizza Hut and Taco Bell on Jamaica Avenue, you might never actually find each other.
After working with address data for the past year or so, my answer is yes please.
Address data is so incredibly difficult to work with and it's pretty clear that it's difficult for everyone involved. Census data is incorrect, OSM is often incorrect, other free sources are filled with typos, post office is consistently bad (No, my last name is not Nicholson...), shapefiles are often haphazardly done. It's so difficult to work with. That said, the amount of quality work to even get it to this point is amazing. Serious kudos to everyone who helps out here.
I've spent an asinine amount of time recently trying to get Chicago's parking ticket data cleaned up. Lake Shore drive is probably the #1 culprit:
LAKE SHORE DDRIVE
LAKE SHORE DER
LAKE SHORE DE WEST
LAKE SHORE DIE
LAKE SHOR EDR
LAKE SHORE DR ''
LAKE SHORE DR AV
LAKE SHORE DR AVE
LAKE SHORE DR EAST
LAKE SHORE DREIVE
Given how many of those are typos I'm not sure how much advantage there is in replacing them with compressed incomprehensible strings. Typo one of these map codes and you'll end up in a different zip code and at first glance nothing will look wrong because they are designed for machines, not people.
Well, more it would emphasize (and pretty much require) a better organized system. The lack of emphasis on proper addressing from everyone makes life pretty hard. :)
To some extent, this could be addressed with standard error detection/correction techniques (e.g. error-correcting codes). But that would make the strings longer and often wouldn't help until they made it to a computer anyway.
I'm not sure I understand how that would even be possible. I'm in an unfamiliar neighborhood without my phone, looking for a business, and all I have to go by is: WQ.TY. How the hell am I going to find it? That's not written anywhere. Even if I know I'm currently at YW.SRN, how does that help me? With number, street, city, I can get to most places by just looking around at street signs and asking people.
Yes, as the article points out, there are places with unnamed streets. That's a bummer. But these map codes don't help unless the proposal is also to put signs up everywhere telling people where their map codes are and how to get to the next ones over.
"I'm not sure I understand how living in cold climates would even be possible. I'm in an unfamiliar neighborhood without my clothes. How the hell am I going to stay warm?"
In practice, you could either (1) not go to unfamiliar places without your phone, or (2) ask someone who does have a phone for directions.
cool. Maidenhead seems more structured and easier to add precision by adding pairs of characters, compared to MGRS.
cons: standardised only upto 4 pairs.
This sounds like what3words (http://what3words.com), except they're using unpronounceable alphanumeric addresses whereas what3words uses 3 actual words (and what3words is 3x3 meters instead of 5x5 meters). For example, for the coordinate that "97.N7" maps to, what3words calls "narrow.career.puppets".
One of the big differences that I see is that mapcodes are more address-like and what3words are more hash-like—two similar mapcodes are nearby (and that's by design), but two similar what3words addresses may be on opposite sides of the planet (and that's also by design).

And you should have a look at the criticisms of Ireland's recently introduced Eircode system: http://www.techcentral.ie/eircode-and-the-geographical-forma...
