Street View has captured 20 petabytes of data, the company said, from cameras mounted on cars, boats, snowmobiles, and even people. For mapping outdoor space, such as national parks and places that vehicles can't access, Google showed off a prototype back-mounted camera rig, which weighs about 35 pounds (check out the video below).

The camera has 15, 5-megapixel lenses and the battery for the rig lasts all day, Vincent said. "If you hike with a partner, they'll be in every scene," he quipped.
