Which term refers to a computer system that stores, organizes, analyzes, and displays geographic data into different layers?

• A. Human Geography
• B. Physical Geography
• C. Perceptual/Vernacular Region
• D. Geographic Information System (GIS)

Answer: (D)

Geographic Information System is a computer system designed to store, organize, analyze, and display geographic data in layers. Each layer holds a specific kind of geographic information—roads, land use, elevation, population—so you can overlay them to see how features relate. This layered approach makes it possible to perform spatial analyses (like finding the best site for a facility based on distance and terrain) and to visualize complex data on maps. The other terms describe geographic concepts rather than a software tool: human geography and physical geography refer to branches studying people and their environments, while a perceptual/vernacular region is a way people mentally divide space, not a digital system for managing data.
