GIS & REMOTE SENSING
A sensor is a device that produces an output signal for the purpose of sensing a physical phenomenon. In Remote Sensing, using scanning systems, which employ a Sensor with a narrow Instantaneous Field of View (IFOV) that sweeps over the terrain.

In remote sensing, sensors are devices that detect and measure electromagnetic radiation reflected or emitted from Earth’s surface. These sensors are broadly classified based on their source of energy and the type of data they collect. What is Sensor? A Sensor is a device that produces an output signal for the purpose of sensing a
SONAR- Sound Navigation and Ranging Introduction Sound Navigation And Ranging (SONAR) is exploring and mapping the ocean, because sound waves travel farther in the water than do Radar and light waves. The Sonar is a technique that uses sound propagation to navigate, measure ranging, communicate with or detect objects on or under the surface of
RADAR- Radio Detection and Ranging Introduction Radio Detection and Ranging (RADAR) is a detection system that uses radio waves to determine the distance, angle, and radial velocity of objects relative to the site. It is widely used in applications ranging from military surveillance to weather forecasting and geographical mapping. The term Radar was minted in 1940 by
