Google Indoor Maps was introduced in 2011 for select malls and shopping centers.
Now, if you are using the latest Google Search App on Android, a Google Now card may appear and show you a searchable card that lets you find the stores in the mall. It may also help you walk directly to the store using Google’s indoor maps feature. Google said, “with one tap, you’ll be taken to the indoor map in Google Maps with a pin showing you exactly where the store is.”
Google posted the news on Google+ on Saturday saying:
Finding the directory in a five-story mall is hard enough, let alone the actual store you’re looking for. Now in some malls, Google Now will show you a searchable directory so you can quickly find a specific store or type of store, like clothing or sporting goods. With one tap, you’ll be taken to the indoor map in Google Maps with a pin showing you exactly where the store is. Try it out now in the U.S. and Japan by updating your #GoogleSearch app for Android: http://goo.gl/idgt3y—we’ll add more malls so stay tuned if you don’t see your favorite just yet. Unfortunately, we can’t help you decide what color sweater to buy for your mother. :)
