Google announced that it has added indoor maps and walking directions for 20 museums in the U.S. to Google Maps for Android on phones and tablets.

But Google Maps for Android has got wayfinding inside your favorite museums down to a science,” says Google’s Cedric Dupont. “With indoor maps and walking directions for U.S. museums now available on your Android phone or tablet, you can plan your route from exhibit to exhibit, identifying points of interest along the way, including between floors.”
