In this Monday Oct. 22, 2012, photo, Google operations manager Steve Silverman shows low-resolution images of photos gathered by the Trekker on an Android phone during a demonstration for the media along the Bright Angel Trail at the South Rim of the Grand Canyon National Park in Arizona. The search engine giant is using the Trekker, a nearly 40-pound, backpack-sized camera unit, to showcase the Grand Canyon’s most popular hiking trails on the South Rim and other off-road sites. It's the latest evolution in mapping technology for the Mountain View, Calif., company, which has used a rosette of cameras to photograph thousands of cities and towns in dozens of countries for its Street View feature.
