Geospatial analysis uses which technology to analyze spatial relationships in disease data?

• A. Public health survey data
• B. Geographic Information Systems (GIS)
• C. Clinical trial protocols
• D. Market research data

Answer: (B)

Geospatial analysis examines how disease patterns relate to location, and the technology that enables this is Geographic Information Systems (GIS). GIS lets you store health data tied to geographic coordinates, visualize cases on maps, and perform spatial analyses such as overlaying disease data with environmental layers, measuring distances, and identifying clusters or hotspots. This ability to integrate location with health attributes and run spatial operations is what makes GIS essential for analyzing spatial relationships in disease data. Public health survey data is valuable for measuring indicators, but it isn’t the tool that analyzes spatial relationships by itself. Clinical trial protocols describe how a study is conducted, not how geography is analyzed. Market research data focuses on consumer patterns, which is a different application area.
