History
1858 Balloonist G.Tournachon made photographs of Paris from his balloon.
Systematic aerial photography developed for military and reconnaissance purposes beginning in World War I and reaching a climax during the Cold War .
Artificial satellites in the latter half of the 20th century.

Balloon photography (1858)
Kite photography (1890)
Pigeon cameras (1903)
Aircraft (WWI and WWII)

Optical Remote SystemOptical remote sensing makes use of visible, near
infrared and short-wave infrared sensors to form images of the earth's surface by detecting the solar radiation reflected from targets on the ground.
Panchromatic Imaging SystemA single channel sensor is used to detect radiationIf range of wavelength and the visible range become
same then the imagery will appear as a black and white photograph taken from space
Multispectral Imaging SystemUses a multi channel detector and records radiation
with a narrow range
Brightness and color informatics are available
Super Spectral Imaging SystemFiner spectral feature that capture by the sensors.
RADAR SystemRadio Detection And RangingObject detection system which uses electromagnetic
waves determine range, direction or speed
LiDAR SystemLight Detection And RangingMeasures distance by sending pulses of laser light that
strike and reflect from the surface of earth.
