What do you get when you put an almost 4-foot high backpack on someone that's barely 5-foot-2? So it wasn't the most graceful when I tried on Google's Street View Trekker, one of several pieces of equipment the company uses to capture its Street View imagery. The 3-foot-9-inch high (1.2m) Trekker consists of 15 cameras in a ball-like shape, mounted on a pole, powered by a computer backpack. The set up is fully waterproof and battery-powered up to 8 hours.
