2. 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.

3. Aerial Photos
 Balloon photography
(1858)
 Kite photography (1890)
 Pigeon cameras (1903)
 Aircraft (WWI and
WWII)
 Space (1947)

 Hyper spectral Imaging System
 RADAR System
 LiDAR System

11. Optical Remote System
 Optical 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.

12. Panchromatic Imaging System
 A single channel sensor is used to detect radiation
 If range of wavelength and the visible range become
same then the imagery will appear as a black and white
photograph taken from space

13. Multispectral Imaging System
 Uses a multi channel detector and records radiation
with a narrow range
 Brightness and color informatics are available

14. Super Spectral Imaging System
 Finer spectral feature that capture by the sensors.

15. RADAR System
 Radio Detection And Ranging
 Object detection system which uses electromagnetic
waves determine range, direction or speed

16. LiDAR System
 Light Detection And Ranging
 Measures distance by sending pulses of laser light that
strike and reflect from the surface of earth.

17. Application Area
 Forestry
 Agriculture
 Hydrology
 Sea Ice
 Land Cover & Land Use
