Google Earth streams the world over wired and wireless networks 
enabling users to virtually go anywhere on the planet and see places 
in photographic detail.  This is not like any map you have ever 
seen.  This is a 3D model of the real world, based on real satellite 
images combined with maps, guides to restaurants, hotels, 
entertainment, businesses and more.  You can zoom from space to 
street level instantly and then pan or jump from place to place, city 
to city, even country to country.

Get Google Earth.  Put the world in perspective.
