Geographic Information System (GIS) Technology
GIS is a collection of computer hardware, software,
and geographic data for capturing, managing, analyzing,
and displaying all forms of geographically referenced
information. Geographical Information System (GIS)
is a new and valuable tool of the 'information revolution'
with the capability of combining attribute and spatial
data with mapping systems and cartographic modeling
tools. |

It permits the acquisition, storage, analysis, management
and presentation of large amounts of geographic or spatial
data with the ai, of solving a geographic problem. |

In the recent years,
the application of GIS in business has grown
rapidly. Major retailers, automobile dealerships,
video rental companies, media organizations,
and fast food corporations are just some of
the many businesses around the world that have
discovered the value of GIS. Research has shown
that since more than 80 per cent of all information
in an organization can be geographically referenced,
business strategists are finding GIS to be an
ideal tool for identifying and expanding markets,
and increasing profits. |

A GIS is most often associated with a maps. A map, however, is only
one way you can work with geographic data in a GIS,
and only one type of product generated by a GIS. This
is important, because it means that a GIS can
provide a great deal more problem-solving capabilities
than using a simple mapping program or adding data
to an online mapping tool (creating a "mash-up").
A GIS can be viewed in three ways:
1. The Database View:
A GIS is a unique kind of database of the world—a
geographic database (geodatabase). It is an "Information
System for Geography." Fundamentally, a GIS is
based on a structured database that describes the world
in geographic terms.

2. The Map View: A
GIS is a set of intelligent maps and other views that
show features and feature relationships on the earth's
surface. Maps of the underlying geographic information
can be constructed and used as "windows into the
database" to support queries, analysis, and editing
of the information. This is called geovisualization.

3. The Model View:
A GIS is a set of information transformation tools
that derive new geographic datasets from existing
datasets. These geo-processing functions take information
from existing datasets, apply analytic functions,
and write results into new derived datasets.
