What is a GIS? (adapted from http://egsc.usgs.gov/isb/pubs/gis_poster)
A geographic information system, or GIS, is a computer system capable of capturing, storing, analyzing, and displaying geographically referenced information; that is, data identified according to exact geographical location. A GIS can help us to view, understand, question, interpret, and visualize data in many ways that reveal relationships, patterns, and trends. These data can then be used to help decision makers make more effective decisions. However, these goals can be achieved only if the data in the system is both adequate and as precise as possible.
