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.
Electromagnetic Radiation (EMR) EMR refers to the energy that travels through space as oscillating electric and magnetic fields. It is the fundamental mechanism by which energy moves through the Electromagnetic spectrum. What is the Electromagnetic Radiation? Electromagnetic Radiation (EMR) or Electromagnetic energy is the energy propagated in the form of an advancing interaction between electric […]
Summary: –The Electromagnetic spectrum is the complete range of electromagnetic waves arranged by their frequency and wavelength. It includes, in order from longest wavelength to shortest: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. Each type of wave has unique characteristics and uses. Electromagnetic Spectrum (EMS) Unveiling the Invisible: The world of
