Google to show off Grand Canyon

Internet giant Google has taken its all-seeing eyes – mounted for the first time on a backpack - into the Grand Canyon, to show the US attraction’s most popular hiking trails.

The move is the latest evolution in mapping technology for the company, which has photographed thousands of cities in dozens of countries for its Street View feature. With a click of the mouse, internet users are transported virtually for a 360-degree view of locales they may have read about only in tourist books and seen in flat, 2-D images.
