It's a new frontier for Google Maps, as the search engine's service moves indoors for some.
FOX News Radio's Lilian Woo has details in this "FOX on Tech":
Your Google Map can now see past the end of the runway, as indoor spaces such as airports and shopping malls in the U.S. and Japan get included in the internet giant's mobile mapping service.
San Francisco International and Chicago-O'Hare Airports, as well as some giant retailers, among those partnering with Google, which hopes its index will expand as shopping and transportation hubs submit indoor floorplans.
For now, the indoor maps can only be viewed on smartphones and tablet computers that run on the company's Android software.
