Geographic Information Systems (GIS)

A Geographic Information System (GIS) is an automated mapping system that uses computers to help map and analyze data that exist on the earth according to their geographic location. With a GIS, you can capture spatial information and store it, integrate it, manipulate it, analyze it, and display it. This spatial information is able to help the user make decisions and help resolve issues before "real-time" events begin.
