Geographic Information System

GIS, computer system that can store manipulate and display geographically referenced information

A geographic information system (GIS) (also known as geographical information system, particularly in the UK, and geomatics in Canada) is a system for capturing, storing, analyzing and managing data and associated attributes which are spatially referenced to the earth. In the strictest sense, it is a computer system capable of integrating, storing, editing, analyzing, sharing, and displaying geographically-referenced information. In a more generic sense, GIS is a tool that allows users to create interactive queries (user created searches), analyze the spatial information, edit data, maps, and present the results of all these operations. Geographic information science is the science underlying the geographic concepts, applications and systems, taught in degree and GIS Certificate programs at many universities.

<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.

A computer system designed for storing, manipulating, analyzing, and displaying data in a geographic context.

Computerized systems used to compile, retrieve, analyze, and display spatially referenced data. Farming activities that utilize GIS typically include harvesting, fertilizing, pest control, seeding, and irrigation. Use of GIS is called precision farming.
