A Geographical Information System (GIS) is a system designed to capture, store, manipulate, analyze, manage and present all types of spatial, or geographic, data. The acronym “GIS” is sometimes used in the area of Geographic Information Science (GIScience) in referring to the academic discipline that studies geographic information systems, and has become a formidable domain within the broader academic discipline of geoinformatics. In a general sense, the term describes any information system that performs the aforementioned tasks (integrating, storing, editing, analyzing, sharing and displaying info of a geographic nature); GIS applications are tools that allow users to create interactive queries (i.e. user-created searches), analyze spatial information, edit data in maps and present the results of all these applications. As of late, GIS has become a broad term referring to a number of different technologies, processes and methods.
