Detailed explanation-1: -Remote sensing is the process of detecting and monitoring the physical characteristics of an area by measuring its reflected and emitted radiation at a distance (typically from satellite or aircraft). Special cameras collect remotely sensed images, which help researchers “sense” things about the Earth.
Detailed explanation-2: -Remote Sensing techniques can be immensely helpful in inventory of irrigated land, identification of crop types, crop extent, crop condition and estimation of crop yield, as demonstrated in various investigations in India and in other countries.
Detailed explanation-3: -Environmental monitoring by remote sensing is based on processing data and images acquired by sensors on satellites and other types of platforms, to extract information about targets on the earth’s surface, or processes of interest over time.
