Ever been lost in a shopping centre? Worse still, ever been stranded in Ikea?
If you have, rejoice - for the best mapping software out there, Google Maps, now works indoors.
Actually, that's stretching the truth ever so slightly since the new Google Maps 6.0 for Android - released today - only really works that way in the US and Japan. And only in selected locations. But regardless, it's an amazing achievement and exciting sign of things to potentially come.
We're not sure how exactly it would work without a GPS signal but we're promised that Google Maps 6.0 can even detect what floor of a building you're on and adjust itself so you see what's around you, not above or below. The tech-speak is that the "the location algorithm is finely tuned, so it should work as well indoors as it does outdoors."
Anyway, if you happen to be reading this from one of the two above nations, the full list of working indoor premises is as follows: Mall of America, IKEA, The Home Depot, select Macy’s and Bloomingdale’s, Daimaru, Taskashimaya and Mitsukoshi locations, Hartsfield-Jackson Atlanta International Airport (ATL), Chicago O’Hare (ORD), San Francisco International Airport (SFO) and Narita International (NRT) and JR and Tokyu Corporation.
If you fancy seeing it in action, Google has helpfully dished up a few official vids on YouTube for you to peruse.
