I love Google Earth, not only can I get directions on how to get there, but it also give me a snap shoot of what to look for. I am a very visual person and this is the best navigation experience I have had the pleasure to use.
Fun! I can tour any place on Earth I can think of. The only improvement I can think of is that when I fly somewhere, I would like to touch the ground and walk where ever I want. Also I would want to investigate things super close-up.
Google Earth is a program that creates a virtual globe that represents the Earth from the juxtaposition of satellite photographs. There are three versions, the free one for personal users, Google Earth (Enterprise) and Google Earth Pro. Many interesting features: Flight simulator, Sky and Mars, Street Views and 3D Buildings and the fantastic Google Ocean.
