Which of the following is a function of GIS?

• A. Map and analyse data
• B. Locate position
• C. Get emergency support
• D. Track inventory

Answer: (A)

Geographic Information System is built to visualize data on maps and analyze how different data layers relate to each other geographically. Mapping data and performing spatial analysis lets you see patterns, relationships, and trends across locations, such as how soil types, rainfall, and crop yields interact, or where risk factors are most concentrated. That core capability—creating maps and analyzing spatial data—is what GIS is designed to do, making it the best description of its function.

Locating a position is a capability you can achieve with GIS, but it’s not the defining function being tested here. Getting emergency support or tracking inventory are more specific applications that can be supported by GIS, not the fundamental purpose of the system.
