Google Maps adds indoor views of major attractions on the regular. Ahead of this summer's Olympic games in Rio de Janeiro, the company is taking you inside the 25 indoor venues that will host sporting events in a few weeks. There are "enhanced views" of the 12 outdoor venues as well, with maps for these stadiums and arenas showing locations for restrooms, concession stands, info desks and ATMs. Real-time transit info for the Brazilian city was added to Google Maps recently, so if you're traveling to the games, you'll have a familiar guide. If you're not making the trip, you can still scope out where the games will be held from the comforts of home.
