A
Geographic Information System (GIS) is a tool that uses
|
|
|
the
power of the computer to pose and answer geographic
|
|
|
questions. The user guides the program to arrange
and
|
|
|
display
data about places on the planet in a variety of ways
|
|
-
including maps, charts and tables.
The hardware and
|
|
|
software
allows the users to see and interact with data in
|
|
|
new
ways by blending electronic maps and databases to
|
|
|
generate
color-coded displays. Users can
zoom in and out
|
|
|
of
maps freely, add layers of new data, and study detail
|
|
|
and
relationships.
