Google has mapped 98% of the inhabited world. If people live there, then Google has probably grabbed a satellite or street view image of that place. The immense value of mapping the globe goes beyond navigation, though. Interactive digital maps of the Earth will have a great impact on tourism, education, entertainment, and more.

Now that Google Earth unveiled new tools for anyone to create tours, presentations, games, etc, we should see the 36 million square miles of free Maps go to good use.
