This ppt will tell you about remote sensing and its utilization

3.  What is Remote Sensing ?
Remote sensing is a method of obtaining
information about the properties of an object without coming into
physical contact with it.
 Sensing of electromagnetic energy operated
from airborne or space borne platforms.
 Sensors collect the data on how earth
surface features emit and reflects
electromagnetic energy.

4. HOW IT WORKS
Process
• Energy source-: 1st requirement, provide
electromagnetic energy to the target.
• Radiation & atmosphere-:
Radiation interact with atmosphere.
• Interaction with the target-:
• Recording of energy by
sensor
• Transmission, reception and processing.
• Interpretation and analysis.
• Application-: final process

5.  Land Use Mapping/ drainage-: obtaining up-to-date land
use pattern of large areas, status of drain especially in tea estate
 Weather Forecasting-: used to warn people about
impending cyclones.
 Environmental Study-: used to study deforestation,
degradation of fertile lands, pollution in atmosphere etc.
 Study of Natural hazards-: helpful to predict the
occurrence of natural hazards.
 Resource exploration-: identifying the sites for
quarrying the minerals and helpful in locating fossil fuel
deposits.

6. ADVANTAGES
Provides a regional view.
Provides high accuracy data.
It Doesn’t Disturb People or the
Environment.
Survey Large and Inaccessible Areas.
Can easily trace out the problems.

7. CONCLUSION
Although remote sensing techniques have
primarily been viewed as a means for
gathering data that are then interpreted by
the user, they are increasingly serving other
roles in scientific and applied research.

8. “Google Earth is an incredible resource
because from hundreds of miles in space,
we can zoom in, and we can find things.
Everyone always looks for their house
first. That is the tip of the iceberg with
remote sensing.”
