What is GIS?
There are different definitions of GIS. Authentic of
them are as under.
1) A geographic information system
(GIS) integrates hardware, software, and data for capturing, managing,
analyzing, and displaying all forms of geographically referenced information. GIS
allows us to view, understand, question, interpret, and visualize data in many
ways that reveal relationships, patterns, and trends in the form of maps,
globes, reports, and charts. A GIS helps you answer questions and solve
problems by looking at your data in a way that is quickly understood and easily
shared. GIS technology can be integrated into any enterprise information system
framework.
2) An information system that deals
with spatial information, Often called "mapping software," it links
attributes and characteristics of an area to its geographic location. It is
used in a variety of applications, including exploration, demographics,
dispatching, tracking and map making. Using satellites and aerial photography,
the U.S. Geological Survey and other organizations have developed digital maps
of most of the world. Unlike paper maps, digital maps can be combined with
layers of information.
