A Geographic information system (GIS) is a computer system for capturing, storing, checking, and displaying data related to positions on Earth’s surface. GIS can show many different kinds of data on one map, such as streets, buildings, and vegetation. This enables people to more easily see, analyze, and understand patterns and relationships. Many other implementations of GIS like satellite image processing and registration, Development planning, database creation and integration etc. add to the important role played by GIS.
