Geographic Information Systems (GIS) are used in public health to map and understand the distribution of health and disease in communities. The Epidemiology Unit coordinates GIS training and resources in the Department, including software licensing, access to geographic data sources, and training sessions.

The Epidemiology Unit generates various maps that are important for the practice of public health. Many of these maps can be found through the links below. However, if you have more specialized data needs, please contact us. A GIS service request form is available through the link below:
