GIS data sets can be useful for many purposes. They are used primarily to display data geographically. In public health, applications for GIS are becoming more accessible as geo-coded health data and environmental exposure data increasingly become available, and new and easier-to-use GIS software is developed. The U.S. Agency for Toxic Substances Disease Registry (ATSDR) uses GIS to monitor the health of persons living near hazardous waste sites, and to identify areas of potential concern resulting from accidental release of chemicals in the environment.

Sharing non-sensitive data about the urban and rural environment allows researchers and technologists to create new ways of understanding nature and society.
The use of digital mapping is becoming more important in the decision-making process during responses to emergencies. Below are examples of tools and resources that have been used in responses and events.
