About Google Earth
Google Earth is a free, powerful program that lets you fly anywhere on Earth to view satellite imagery, maps, terrain, and 3D buildings, from galaxies in outer space to the canyons of the ocean.
You can view maps from thousands of feet up or at street level. Fly over buildings or read the signs on their ground-floor windows. Download the ARIEL maps and then customize them with your own links, locations, popups, photographs, and more.
