A Geographic Information System (GIS) is a system designed to capture, store, manipulate, analyze, manage, and present spatial or geographic data. It is the science underlying geographic concepts, applications, and systems. 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.

GIS can refer to a number of different technologies, processes, and methods. It is attached to many operations and has many applications related to engineering, planning, management, transport/logistics, insurance, telecommunications, and business. For that reason, GIS and location intelligence applications can be the foundation for many location-enabled services that rely on analysis and visualization.

Work includes data quality assessment and conversion, linking spatial data to numerical databases, use of GPS in automated GIS data capturing, data presentation and integrated analysis, GIS software and hardware selection, and GIS applications for decisions support and management.
