GIS (Geographic Information System) applications are computer software that show digital maps accompanied by tools that you can use to view the map, query for information and print a map that you composed.
GIS is a computer-based technology that creates, stores, organizes, analyzes and displays maps of anything that can be represented graphically. Of special note is that the mapped entities have “real world” coordinates tied directly to the earth’s surface. When all of the mapped entities have coordinates, you can see everything in relation to everything else. You immediately see the “connectedness of all things.” Attributes (facts) about those mapped entities are included with the map so that you can inquire about those characteristics. If a picture is worth a thousand words, a GIS map is worth ten thousand.
