Google Earth is a virtual Earth globe on which you can see maps and the geography of the entire planet Earth on your computer’s screen.

This program will let you travel to any part of the world to see reliefs, roads, photographs, 3D constructions and all sorts of data about the places you visit. The secret is in the different layers Google Earth will provide you, since each of them concentrates on a specific type of information.

This application will be very useful for you, thanks to its search engine that will let you locate buildings and addresses as well as the best route to take and the distance between any two points. You will even be able to take a look at the surroundings of the points you choose, using the Street View technology.

Google Earth will also let you fly over the places you want to with a simple flight simulator. Thus the program becomes the only tourist guide you’ll need to learn everything about our planet.
