From Google: Google Earth puts a planet's worth of imagery and other geographic information right on your desktop. View exotic locales like Maui and Paris, as well as points of interest such as local restaurants, hospitals, and schools.

With Google Earth you can fly from space to your neighborhood--just type in an address and zoom right in, search for schools, parks, restaurants, and hotels. Get driving directions, tilt and rotate the view to see 3D terrain and buildings, save and share your searches and favorites and even add your own annotations.
