  Geographic Information System
  
     <application> (GIS) A computer system for capturing, storing,
     checking, integrating, manipulating, analysing and displaying
     data related to positions on the Earth's surface.  Typically,
     a GIS is used for handling maps of one kind or another.  These
     might be represented as several different layers where each
     layer holds data about a particular kind of feature
     (e.g. roads).  Each feature is linked to a position on the
     graphical image of a map.
  
     Layers of data are organised to be studied and to perform
     statistical analysis (i.e. a layer of customer locations could
     include fields for Name, Address, Contact, Number, Area).
     Uses are primarily government related, town planning, local
     authority and public utility management, environmental,
     resource management, engineering, business, marketing, and
     distribution.
