• Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object and thus is in contrast to on-site observation.
  • It is used in numerous fields, including geography, land surveying, and most Earth science disciplines (for example, hydrology, ecology, meteorology, oceanography, glaciology, geology).

• Components of Remote Sensing: 
  • Energy Source or Illumination. 
  • Interaction with the Target 
  • Recording of Energy by the Sensor. 
  • Transmission, Reception, and Processing. 
  • Interpretation and Analysis.
