Getting lost can be half the fun of any leisurely museum excursion, but if you'd prefer to navigate your indoor outing with a level of precision typically reserved for trips across town, you'll want to bring Google Maps along on your next journey to the Smithsonian. Mountain View just added 20 US museums to its battery of 10,000 indoor schematics, 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, 17 Smithsonian museums and the National Zoo in DC. You can find the plans for any venue by searching or hitting the current location button once you're on site, and Google plans to continue growing its collection, with SFMOMA, The Phillips Collection, the Nelson-Atkins Museum of Art and the National WWII Museum in New Orleans set to join soon. Meanwhile, institutions interested in joining forces with Google can use the company's Floor Plans tool to get the process started. Full details are at the source link below.
