A geographic information system (GIS) is a system for creating, storing, analysing and managing spatial data and associated attributes. In the strictest sense, it is a computer system capable of integrating, storing, editing, analysing, sharing, and displaying geographical information. In a more generic sense, GIS is a tool that allows users to create interactive queries (user created searches), analyze the spatial information, and edit data. - from the Dictionary of Environmental Science and Technology
