Transcript of "Ppt on remote sensing system"

  1. 3. Presented by BCA-3A (Kreatipedia )
  2. 4. <ul><li>The gathering of information from an object or surface without direct contact. </li></ul>
  3. 5. <ul><li>Lithosphere  </li></ul><ul><li>Biosphere </li></ul><ul><li>Remote Sensor </li></ul><ul><li>Reflecting surfaces </li></ul>
  4. 6. <ul><li>1858 Balloonist G.Tournachon made photographs of paris from his balloon. </li></ul><ul><li>Systematic aerial photography developed for military and reconnaissance purposes beginning in World War I and reaching a climax during the Cold War  </li></ul><ul><li>Artificial satellites in the latter half of the 20th century </li></ul>
  5. 7. <ul><li>Passive Remote Sensing </li></ul><ul><ul><ul><li>Photography </li></ul></ul></ul><ul><ul><ul><li>Radiometers </li></ul></ul></ul><ul><ul><ul><li>Infrared </li></ul></ul></ul><ul><li>Active Remote Sensing </li></ul><ul><ul><ul><li>RADAR </li></ul></ul></ul><ul><ul><ul><li>LiDAR </li></ul></ul></ul>
  6. 8. <ul><li>Geology </li></ul><ul><li>Environmental monitoring </li></ul><ul><li>Commercial forestry </li></ul><ul><li>Reconnaissance mapping </li></ul>
  7. 9. <ul><li>Forestry </li></ul><ul><li>Agriculture </li></ul><ul><li>Hydrology </li></ul><ul><li>Sea Ice </li></ul><ul><li>Land Cover </li></ul><ul><li>& </li></ul><ul><li>Land Use </li></ul>
  8. 11. <ul><li>Spectral Signatures </li></ul><ul><li>Image Acquisition </li></ul><ul><li>Spatial Resolution </li></ul><ul><li>Spectral Resolution </li></ul><ul><li>Multispectral Images </li></ul><ul><li>Radiometric Resolution </li></ul>
  9. 12. <ul><li>signatures produced by wavelength-dependent absorption </li></ul><ul><li>the ratio of reflected energy to incident energy as a function </li></ul>
  10. 13. <ul><li>radiant energy that is measured by an aerial or satellite sensor </li></ul><ul><li>electromagnetic energy returned from the Earth’s surface can be detected by a light-sensitive film </li></ul>
  11. 14. <ul><li>a function of the design of the sensor </li></ul><ul><li>detectors in a remote sensor measures energy received from a finite patch of the ground </li></ul><ul><li>surface </li></ul>
  12. 15. <ul><li>Parallel sensor arrays detecting radiation in a small number of broad wavelength bands </li></ul><ul><li>allow discrimination of different types of : </li></ul><ul><li>vegetation, </li></ul><ul><ul><li>rocks and soils, </li></ul></ul><ul><ul><li>clear and turbid water, and </li></ul></ul><ul><ul><li>some man-made materials </li></ul></ul>
  13. 16. <ul><li>Quantized incoming energy </li></ul><ul><li>analyze the numerical values in the bands of a multispectral image </li></ul>
  14. 17. <ul><li>High Resolutions Low Resolution </li></ul>
  15. 18. <ul><li>Optical System </li></ul><ul><ul><ul><li>Panchromatic imaging system </li></ul></ul></ul><ul><ul><ul><li>Multispectral imaging system </li></ul></ul></ul><ul><ul><ul><li>Super spectral Imaging System </li></ul></ul></ul><ul><ul><ul><li>Hyper spectral Imaging System </li></ul></ul></ul><ul><li>RADAR System </li></ul><ul><li>LiDAR System </li></ul>
  16. 19. <ul><li>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. </li></ul>
  17. 20. <ul><li>A single channel sensor is used to detect radiation </li></ul><ul><li>If range of wavelength and the visible range become same then the imagery </li></ul><ul><li>will appear as a black </li></ul><ul><li>and white photograph </li></ul><ul><li>taken from space </li></ul>
  18. 21. <ul><li>Uses a multi channel detector and records radiation with a narrow range </li></ul><ul><li>Brightness and color </li></ul><ul><li>informatics are available </li></ul>
  19. 22. <ul><li>Finer spectral feature that capture by the sensors . </li></ul>
  20. 23. <ul><li>RAdio Detection And Ranging </li></ul><ul><li>Object detection system which uses electromagnetic waves determine range, direction or </li></ul><ul><li>speed </li></ul>
  21. 24. <ul><li>Detect the presence of an object at a distance </li></ul><ul><li>Detect the speed of an object </li></ul><ul><li>Map something </li></ul><ul><ul><ul><li>Echo </li></ul></ul></ul><ul><ul><ul><li>Doppler Shift </li></ul></ul></ul>
  22. 25. <ul><li>Light Detection And Ranging </li></ul><ul><li>Measures distance by sending pulses of laser light that strike and reflect from the surface of earth. </li></ul>
