Data Visualization in Environmental Public Health: From Data to Insight
Identifying Geographic Patterns
Many environmental health issues have a geographic component. Understanding where conditions occur is often just as important as understanding how often they occur.
GIS allows EPH professionals to visualize, analyze, and communicate spatial relationships. Maps can reveal patterns, concentrations, service gaps, and geographic disparities that tables or charts might not show. EPH commonly uses several map types. Different map types answer different geographic questions: where events occurred, how a rate varies by area, or how a pattern changes over time.
