GIS Image

Stands for "Geographic Information Systems." GIS tools are used to gather and analyze data about the surface of the earth. The data can be used to create charts, maps, and 3D models of the earth's surface. This includes hills, mountains, trees, buildings, streets, rivers, and pretty much anything else. Sounds fun, but how is it used? Well, organizations such as the police and fire department can use the data to develop emergency routes. The government can use the data to measure the growth and expansion of cities or the depletion of forests. Most importantly, however, GIS can assist with special effects by simulating landscapes and terrain in action movies.

GIS files created with ArcGIS software use the .e00 file extension.
