4. REMOTE SENSING
Remote Sensing is defined as the science and technology by which the characteristics of
objects of interest can be identified, measured or analyzed the characteristics without
direct contact.
Electro-magnetic radiation which is reflected or emitted from an object is the usual
source of remote sensing data. However any media such as gravity or magnetic fields can
be utilized in remote sensing

5. Importance of Remote Sensing
⮚ It is possible to collect data from dangerous or inaccessible areas, with growing relevance in
modern society.
⮚ It replaces slower, costly data collection on the ground, providing fast and repetitive
coverage of extremely large areas for everyday applications, ranging from weather forecasts
to reports on natural disasters or climate change.
⮚ Remote sensing is also an unobstructive method, allowing users to collect data and perform
data processing and GIS analysis offsite without disturbing the target area or object.
⮚ Monitoring floods and forest fires, deforestation, polar bears, chemical concentrations, and
earthquakes are just a few cases in which geospatial remote sensing provides a global
perspective and actionable insights that would otherwise be unattainable.

6. PRINCIPLE BEHIND REMOTE SENSING
⮚ Detection and discrimination of objects or surface features means detecting and recording of
radiant energy reflected or emitted by objects or surface material .
⮚ Different objects return different amount of energy in different bands of the electromagnetic
spectrum, incident upon it. This depends on the property of material (structural, chemical,
and physical), surface roughness, angle of incidence, intensity, and wavelength of radiant
energy
⮚ The Remote Sensing is basically a multi-disciplinary science which includes a combination
of various disciplines such as optics, spectroscopy, photography, computer, electronics and
telecommunication, satellite launching etc. All these technologies are integrated to act as one
complete system in itself, known as Remote Sensing System. There are a number of stages in
a Remote Sensing process, and each of them is important for successful operation
