Google Earth is a desktop software package that allows users to view GIS data and services. If you do not currently have Google Earth, you can download it for free at http://earth.google.com/ . (Note: There is also Google Earth Pro which allows users to add GIS data and create fly over movies. Google Earth Pro is not free.)
