A Geographic Information System is a system designed to capture, store, manipulate, analyze,manage, and present all types of geographically referenced data. The acronym GIS is sometimes used to mean geographical information science or geospatial information studies In the simplest terms, GIS is the merging of cartography, statistical analysis, and database technology.
A GIS can be thought of as a system—it digitally creates and "manipulates" spatial areas that may be jurisdictional, purpose, or application-oriented.
Generally, a GIS is custom-designed for an organization. Hence, a GIS developed for an application, jurisdiction, enterprise, or purpose may not be necessarily interoperable or compatible with a GIS that has been developed for some other application, jurisdiction, enterprise, or purpose. What goes beyond a GIS is a spatial data infrastructure (SDI), a concept that has no such restrictive boundaries.
Therefore, in a general sense, the term describes any information system that integrates, stores, edits, analyzes, shares, and displays geographic information for informing decision making. The term GIS-centric, however, has been specifically defined as the use of the Esri ArcGIS geodatabase as the asset/feature data repository central to computerized maintenance management system (CMMS) as a part of enterprise asset management and analytical software systems.
IN WWDSE GIS technology can be used for :
- earth surface-based scientific investigations ;
- reference and projections of a geospatial nature, both artificial and natural ;
- asset management and location planning
infrastructure assessment and development ;
- cartography, for a thematic and/or time-based purpose ;
- criminology ;
- GIS data development ;
- logistics ;
- population and demographic studies ;
- public health planning.
