GIS is a computer system capable of capturing, storing, analyzing, and displaying geographically referenced information. GIS works by relating information from different sources. The power of a GIS comes from the ability to relate different information in a spatial context and to reach a conclusion about this relationship. Most of the information the authors have about their world contains a location reference, placing that information at some point on the globe.
