- Geographic Information System
computer system for capturing, storing, checking, integrating, manipulating,
analysing and displaying data related to positions on the Earth's
surface. Typically, a Geographical Information System (or Spatial
Information System) 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. 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. Uses are primarily government related, town planning,
local authority and public utility management, environmental, resource
management, engineering, business, marketing, and distribution.
