What is a Geographic Information System?

A Geographic Information System (GIS) uses computers and software to map and analyze places and events on the earth's surface. GIS allows a person to view, understand, question, interpret and visualize data in ways that are not possible by simply reading a report or examining figures found in the rows and columns of a spreadsheet.

Nearly all county government information has a geographic component to it. Examples of this include a property's address, a manhole location, a street, and a city's jurisdictional boundary. GIS consolidates and integrates all this diverse information so it can be managed more effectively and efficiently.
