What is a primary capability of GIS in geographic analysis?

• A. It stores, analyzes, and displays spatial data.
• B. It is primarily used to provide GPS coordinates.
• C. It collects remote sensing imagery independently.
• D. It replaces all other data collection methods.

Answer: (A)

The main idea being tested is how GIS handles geographic information by bringing together storage, analysis, and visualization of spatial data. A GIS is designed to keep different layers of geographic information, run spatial operations (like overlay, proximity, and network analysis), and present the results in maps and other visual formats. This integrated workflow—storing multiple spatial datasets, analyzing their relationships, and displaying the outcomes spatially—is what makes GIS a powerful tool for geographic analysis.

While GPS coordinates are a basic output you might get from a GIS, the system’s real strength is not just giving coordinates but combining many layers of spatial data and performing analyses to reveal patterns and relationships. Remote sensing imagery can be used within a GIS, but the software doesn’t collect imagery on its own; data collection is done by other tools or missions. And GIS does not replace all other data collection methods; it relies on a variety of data sources and serves as the platform for analysis and visualization across them.

So, storing, analyzing, and displaying spatial data is the best description of GIS’s primary capability in geographic analysis.
