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 health related fields. GIS helps users understand patterns, relationships, and geographic context. The benefits include improved communication and efficiency as well as better management and decision making. For more details about what GIS can offer please visit the ESRI website. To request a GIS service, please submit a geocoding request or mapping request.

GIS can be used in many different ways for a variety of subjects. Some examples of how GIS can be applied within Public Health include:
- Map public or confidential information by aggregating to census tract, county, or other spatial units
- Analyze spatial variations in health outcomes
- Select new clinic locations based on suitability criteria
- Conduct environmental risk assessments
- Evaluate availability of health care
- List provider locations closest to a given address
- Track the spread of disease
