geographic information system (GIS) (sh) and Differential diagnosis (health)


geographic information system (GIS) (sh)




Computerized system that relates and displays data collected from a geographic entity in the form of a map.

The ability of GIS to overlay existing data with new information and display it in colour on a computer screen is used primarily to conduct analyses and make decisions related to geology, ecology, land use, demographics, transportation, and Other Domains, most of which relate to the human use of the physical environment. Through the process of geocoding, geographic data from a database is converted into images in the form of maps.
