Google, the search engine can help you access satellite photos of North America’s most significant landmarks and locations, including the Grand Canyon, Alcatraz and Mount Rushmore. You need to enter in a zip code and a photo from space of that location – if available – is then shown. At the moment Google only offers satellite images of locations in the US and Canada but Keyhole Corporation, which Google bought last year has data for the whole globe so the service could be rolled out for other countries. The detail in some of the Google photos is impressive – putting zoom at the highest level lets you pick out individual houses and even cars. The catch? There’s a fee to use the service though a free 7 day trial is available. See:
