A geographic information system or GIS is a system designed to capture, store, manipulate, analyze, manage, and present spatial or geographical data. We combine software, hardware, and collected data to analyze and display the geographically referenced data.In general, the term describes any information system that integrates, stores, edits, analyzes, shares, and displays geographic information. GIS applications are tools that allow users to create interactive queries (user-created searches), analyze spatial information, edit data in maps, and present the results of all these operations.
