Geographic information system (GIS)

Combines modern computer and supercomput- ing digital technology with data management systems to provide tools for the capture, storage, manipulation, analysis, and visualization of spatial data. Spatial data contains information, usually in the form of a geographic coordinate system that gives data location relative to the earth’s sur- face. These spatial attributes enable previously disparate data sets to be integrated into a digital mapping environment. (United States Department of Health and Human Services. Healthy People 2010, Chapter 23. Washington, DC: US Department of Health and Human Services; 2000.)
