Google have updated their Google Maps application. so now users can look at the interior of a airports, malls and shops, rather than a grey blob as before. In a few certain places, the maps will show a floor layout and where each shop or business is.
The above image shows before and after images to demonstrate what the new update can do. In this case, it is the interior of the San Francisco International Airport.
Whilst you can only see the interior of buildings in places in the USA and Japan, it is pretty awesome and will definitely by helpful in a large shop.
