Google Maps for Android was recently updated their indoor location database with over twenty popular museums across the U.S, including the de Young Museum in San Francisco, the Philadelphia Museum of Art, Cincinnati Museum Center, the Indianapolis Museum of Art, the American Museum of Natural History, and 17 Smithsonian museums.
Indoor maps originally launched in November, allowing users to set routes within buildings, navigate by floor, and sort through points of interest. It's an awesome feature, and a sensible extension of Google's current walking directions. Who knows, maybe indoor maps will expand to include audio guides that are sensitive to where you are within a building.
A full list of indoor Google Maps is available here, and if you're really into art, be sure to check out the Google Art Project. If you have the latest version of Google Maps for Android, you should be ready to start planning your next museum trip. Do you go often? Which buildings would you like to see with full indoor maps?
