Like the other tools you've been playing with er, learning to use in Eyes in the Sky II, we'll only scratch the surface of what you can do with Google Earth and how you might use it in your classroom. In the past few years, with help from NASA researchers and data, Google Earth has been expanded to include maps of Earth's ocean floor, as well as the Moon, Mars, and the Sky, all using the same familiar 3D interface. As you use Google Earth, you'll come to realize that it's actually a special-purpose GIS tool, capable of displaying many types of data in 4 dimensions ≳ spatial dimensions plus (in some locations, anyway) a time dimension. Google Earth has been described as 'a map of the world on steroids.' It's a free tool for exploring spatial data in an interactive 3D environment.

If you have not installed Google Earth or updated your existing copy of the program to the current version (version 6), please refer to the installation instructions on the Module 2 Review & Install Installing Google Earth page before continuing.
