WEEK TWO
\n<\/strong>SATELLITE REMOTE SENSING
\n<\/strong>
\n\u00a0Remote Sensing is defined as the act of obtaining information about an object without being in direct contact with the object.<\/p>\n

\u00a0A satellite is an artificial body placed in orbit round the earth or on another planet to collect information or for communication.<\/p>\n

\u00a0Satellite remote sensing is a satellite that study the earth’s surface and atmosphere.<\/p>\n

\u00a0APPLICATION OF SATELLITE REMOTE SENSING
\n<\/strong>Satellite remote sensing can be applied in various field of life such as forestry, agriculture, environment, telecommunication, transportation etc.<\/p>\n

\u00a0Energy is the capacity to do work. Energy can take many forms such as light, heat or sound, and it can be transmitted between objects through three processes which are:<\/p>\n

\u00a0Conduction: The objects are in direct physical contact. Energy is transferred from the high energy object to the low energy object until both objects are at the same energy level.<\/p>\n

\u00a0Convection: This occurs in liquid and gases. It is based on currents that distribute energy throughout the volume of liquid or gas.<\/p>\n

\u00a0Radiation: This does not require physical contact or the existence of a liquid or gas.<\/p>\n

\u00a0Environmental remote sensing systems focus on electromagnetic energy, which is a dynamic form of energy caused by the oscillation or acceleration of an electrical charge. All objects that have a temperature higher than absolute zero emit electromagnetic energy. The wavelength of the emmited energy is a function of temperature.
\nAlmost all electromagnetic energy in the earth and its atmosphere is produced by the sun and is transmitted through the vacuum of space by radiation. <\/p>\n
