Geographical Information Systems (GIS)
A geographic information system (GIS), captures, stores, analyzes, manages, and presents data that refers to or is linked to a location.
In the strictest sense, the term describes any information system that integrates, stores, edits, analyzes, shares, and displays geographic information. In a more generic sense, GIS applications are tools that allow users to create interactive queries (user created searches), analyze spatial information, edit data, maps, and present the results of all these operations. Geographic information science is the science underlying the geographic concepts, applications and systems.
