Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

The main idea behind principle of remote sensing is the storing reflected electromagnetic energy by a sensor that is distant from the object being sensed. Basic principles of remote sensing are: 1. Electromagnetic energy striking an object is reflected, absorbed or transmitted. 2. Objects appear as color they most reflects 3. Objects also reflect other portions of electromagnetic spectrum. 4. Detection and discrimination of objects or surface features means detecting and recording of radiant energy reflected or emitted by objects or surfaces.
