Geographic Information Systems (GIS)
A geographic information system (GIS) integrates hardware, software, and data for capturing, managing, analyzing, and displaying all forms of geographically referenced information. It is a computer-based tool for mapping and analyzing things that exist and events that happen on earth. GIS technology integrates database operations and statistical analysis with the unique visualization and spatial analysis benefits offered by maps. These abilities distinguish GIS from other information systems and make it valuable to a wide range of public and private enterprises for explaining events, predicting outcomes, and planning strategies.
