Geographical information system (GIS)

[Rennhack]

A system for linking information to a particular geographical location.  GISs are generally capable of producing maps that show the location of the information.  For example, a GIS containing TENORM information might contain the name and number of acres at a TENORM site as well as information about its longitude and latitude.  A map printed from this system would show locations and sizes of TENORM sites on a map of the United States.
