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: -In current usage, the term remote sensing generally refers to the use of satellite-or aircraft-based sensor technologies to detect and classify objects on Earth. It includes the surface and the atmosphere and oceans, based on propagated signals (e.g. electromagnetic radiation).
Detailed explanation-3: -Remote sensing satellites are also called Earth observation satellites or Earth remote sensing satellites. They’re used as spy satellites or for environmental monitoring, meteorology, and cartography. The most common type are Earth-imaging satellites, which take satellite images similar to aerial photographs.
Detailed explanation-4: -Remote sensing of the earth from satellite systems such as Landsat, Nimbus, and Skylab has demonstrated the potential influence of such observations on a number of major human concerns.
