FORMAL DEFINITION

Geographic information system, GIS (noun)

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. GIS helps users understand patterns, relationships, and geographic context. The benefits include improved communication, efficiency, management, and decision-making.

How is GIS used?

GIS is embedded in the daily operations of virtually every industry. The following are just a few of the thousands of applications.

Choosing the right location

Make better decisions about business growth or service expansion. Know where your best customers are and discover where to find more of them. When selecting the ideal place for a new retail store, distribution hub, or fire station, GIS can bring together all the information important to your decision. Consider what’s nearby, travel times, population numbers, local demographics, site suitability, and competitor locations.

GIS is now more important then ever
