Maps now works indoors! If it’s a fairly well-known place, of course – think shopping malls and airports.
To use the feature, simply search for a location in the Maps app. If it’s eligible, a detailed floorplan will be available. (If you just want to explore, the Philadelphia International Airport and the Westfield Valley Fair in San Jose are both available.)
This includes store details, boarding gates, check-in desks, and more.
You can also search by floor and look for bathrooms. Tapping on an item will bring up further details.
