Geographic Information Systems

Geographic Information Systems (GIS) are computer-based tools used to store, visualize, analyze, and interpret geographic data. Geographic data (also called spatial, or geospatial data) identifies the geographic location of features. GIS combines the visual elements and features on a map with the ability to link characteristics about these features in databases. This relationship provides a means for GIS to locate, display, analyze, and model information.
