GIS is a technology that is used to create, manage, analyze, and map all types of data. GIS connects data to a map, integrating location data (where things are) with all types of descriptive information (what things are like there). This provides a foundation for mapping and analysis that is used in science and almost every industry.
A geographic information system (GIS) is a process that is intended to capture, store, manipulate, analyze, and present all types of geographical data. The essential word in this definition is “geography,” which means that some portion of the information is spatial. In other words, GIS works with data that centers around locations on the earth.
A geographic information system (GIS) consists of integrated computer hardware and software that store, manage, analyze, edit, output, and visualize geographic data. [ 1 ][ 2 ] Much of this often happens within a spatial database; however, this is not essential to meet the definition of a GIS. [ 1 ] In a broader sense, one may consider such a ...

The Canada Geographic Information System (CGIS), initiated in 1963 by the Agriculture Rehabilitation and Development Agency, was the first operational land resource GIS. GIS is now operating under Environment Canada. Another early system was the Geographically Referenced Data Retrieval System ...
Geographic Information Systems (GIS) are powerful tools that allow users to visualize, analyze, and interpret data to understand relationships, patterns, and trends in relation to locations and geography. At its core, GIS is about mapping data: it links locations (where things are) with information (what things are like there). Unlike a simple map, however, GIS can show many kinds of data on ...
