What is GIS?

• A. A statistical method for analyzing climate data.
• B. A computer-based system that links information to locations; governments and businesses use this to make data-driven decisions.
• C. A field of study about continents.
• D. A type of 3D printing technology.

Answer: (B)

Geographic information systems organize data by location so you can map and analyze how different facts relate to places. A GIS is a computer-based system that links information to locations, and governments and businesses use it to make data-driven decisions by combining maps with many data layers—such as demographics, infrastructure, and resources—to see patterns and answer “where” questions. For example, city planners might analyze flood zones, street networks, and population density together to plan evacuation routes or locate new services. The other options describe different ideas: a statistical method for analyzing climate data focuses on data analysis techniques rather than a location-based information system; a field of study about continents is geography in general; and 3D printing technology is not related to mapping or spatial analysis.
