Remote Sensing

Remote sensing is the process where the Remote sensors assemble data by identifying the energy that is replicated from earth. These sensors can be on satellites or aircrafts. The electromagnetic radiation is generally used as an information carrier in remote sensing. Remote sensors collect the information by determining the electromagnetic radiation that is reflected, emitted and absorbed by objects in numerous spectral regions, from gamma-rays to radio waves. To extent this radiation, both active and passive remote sensors are used. Passive remote sensors record natural sensors that is echoed or radiated from the earth surface. The most collective source of detection is sunlight. Active sensors use internal stimulates to assemble data about earth. Remote sensing methods are used to increase enhanced understanding of the earth and its functions. A Global Earth Observation System of Systems (GEOSS) is being established to connect earth observation systems around the world. A comprehensive and synchronized system of earth observations could lead to improved management of environmental data and could fulfil numerous societal benefits.
