A geographic information system (GIS) consists of an integrated hardware, software, and data system that can capture, manage, analyze, and visualize diverse types of geographical information. GIS systems enable researchers to examine data in unique ways so that they can more readily observe and interpret relationships, patterns, and trends in complicated data sets. The National Cancer Institute (NCI) is engaged in a variety of GIS-related activities and initiatives. The NCI GIS site was designed to provide a central source of information about GIS and related resources.
