What is GIS?

From What is GIS? | Geographic Information System Mapping Technology (esri.com):

A geographic information system (GIS) is a system that creates, manages, analyzes, and maps all types of data. GIS connects data to a map, integrating location data (where things are) with all types of descriptive information (what things are like there). This provides a foundation for mapping and analysis that is used in science and almost every industry. GIS helps users understand patterns, relationships, and geographic context. The benefits include improved communication and efficiency as well as better management and decision making.

GIS Applications in Health

From GIS for Health | Public Health, Human Services and Hospitals & Health Systems (esri.com):

Health and human services professionals are benefiting from insights that the power of place brings to their work. Spatial data and geographic information system (GIS) technology can underscore coverage gaps in the populations we hope to reach, the opportunities to improve workflows, and the ability to plan for and mitigate against unforeseen events. Applied GIS leads to improved health outcomes, increased accessibility to health care, and healthier communities.
