PolicyMap is an online geographic information system (GIS) mapping tool that aggregates many types of data for users to create maps and reports for research, grant applications, health policy, market surveys, and other applications. Although the data are amassed from many different sources, they are cleaned and normalized to reduce redundancy and maintain integrity. In addition to federal, state, and local governments, PolicyMap is used by educational institutions, foundations, nonprofit organizations, and health care systems to help make impactful decisions. You can view a recent presentation on this tool on the Library YouTube channel at the following link: Understanding PolicyMap: Beta.
