This institute introduces a broad range of ways that Geographic Information Systems (GIS) can be applied to public health research, practice, and public policy. By the end of the institute, participants will be able to critically analyze maps and research results developed using GIS, learn how to create and analyze thematic maps, geocode addresses, and conduct basic queries, implement a variety of field data collection methods used in GIS such as handheld GPS technology, and develop individual research agendas which incorporate GIS methods.
