What are principles of remote sensing?
Remote sensing uses a part or several parts of the electromagnetic spectrum. It records the electromagnetic energy reflected or emitted by the earth’s surface. The amount of radiation from an object (called radiance) is influenced by both the properties of the object and the radiation hitting the object (irradiance).
What is remote sensing in PDF?
Remote sensing refers to obtaining information about objects or areas by using. electromagnetic radiation (light) without being in direct contact with the object or area.
What are the stages of remote sensing?
What is the process of remote sensing?
- PHASE 1: Energy Source or Illumination.
- PHASE 2: Radiation and the Atmosphere.
- PHASE 3: Interaction with the Target.
- PHASE 4: Recording of Energy by the Sensor.
- PHASE 5: Transmission, Reception, and Processing.
- PHASE 6: Interpretation and Analysis.

What is importance of remote sensing?
The advantages of remote sensing include the ability to collect information over large spatial areas; to characterize natural features or physical objects on the ground; to observe surface areas and objects on a systematic basis and monitor their changes over time; and the ability to integrate this data with other …
What are the four basic components of remote sensing system?
There are four basic components of a remote sensing system ( Fig. 1) including: (1) a target; (2) an energy source; (3) a transmission path; and (4) a satellite sensor (Landsat, SPOT, or the SIR-C radar) which records the intensity of electromagnetic radiation (sunlight) reflected from the earth at different …
