GIS offers many applications and functionality that are tremendously beneficial to the Public Health industry. The ability to visualize cases in space (geographically) and time is invaluable in analyzing spatial clusters of health related events. Further the ability to model the spread of a potential epidemic can literally be a life saver. GIS is a natural choice for solving many Public Health issues including: analyzing the location of diseases; the spread of contagious diseases (both vecor borne as well as the spread through human contact); the cause and effect of environmental factors; as well as the availability of Health facilities. Prerequisite: GIS 4101 or similar GIS course and/or work experience.
