Geographical Information Systems (GIS) are integral to the management of health care data, the mapping of health indexes and the impact of a disease. Through the use of GIS we can locate health care facilities, their accessibility and health care needs which may not be available to certain populations. Health care providers can discover new markets and at the same time improve existing services. The acquired data can aid companies and organizations in catalytic decision making, and to formulate new policies. This paper will present various GIS applications in health care. If these applications are implemented they will prove to be an important tool in decreasing the costs of health care, services and supplies.
