Definition of Remote Sensing

Remote sensing is a process that is used to detect and monitor the physical attributes of an area. This is done by measuring the radiations that are emitted and reflected in that area. This is typically performed through an aircraft or a satellite. The researchers perceive things related to the earth by the images captured by special cameras.


The cameras present on the satellites and aircrafts capture images of large regions of the earth as well as of oceans when the temperature of oceans is changing. The ships have sonar systems with which they take images of the ocean floor. With the help of remote sensing, forest fires can be determined and mapped, the weather can be predicted by tracking the clouds, volcanic eruptions can be seen and the growth of cities over several years can be determined.
