Global Positioning System refers
to a system of satellites and
receivers that allow people and
devices to pinpoint their precise
location on the earth.
Signals are received by a special
electronic device called GPS

Remote Sensing
Use of Earth orbiting satellites to capture information about
the surface and atmosphere below
Remote Sensing is
defined as the
acquisition of
information about an
object without being
in physical contact
with it
Satellite Remote Sensing

What is GIS
A GIS is a computer system capable of capturing, storing,
analyzing, and displaying geographically referenced
information; that is, data identified according to location.
It also includes the procedures, operating personnel, and
spatial data that go into the system.
