  • 1.  
  • 2.  
  • 3. Presented by BCA-3A (Kreatipedia )
  • 4.
    • The gathering of information from an object or surface without direct contact.
  • 5.
    • Lithosphere 
    • Biosphere
    • Remote Sensor
    • Reflecting surfaces
  • 6.
    • 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
  • 7.
    • Passive Remote Sensing
        • Photography
        • Radiometers
        • Infrared
    • Active Remote Sensing
        • RADAR

  • 10.  
  • 11.
    • Spectral Signatures
    • Image Acquisition
    • Spatial Resolution
    • Spectral Resolution
    • Multispectral Images
    • Radiometric Resolution
  • 12.
    • signatures produced by wavelength-dependent absorption
    • the ratio of reflected energy to incident energy as a function
  • 13.
    • radiant energy that is measured by an aerial or satellite sensor
    • electromagnetic energy returned from the Earth’s surface can be detected by a light-sensitive film
  • 14.
    • a function of the design of the sensor
    • detectors in a remote sensor measures energy received from a finite patch of the ground
    • surface
  • 15.
    • Parallel sensor arrays detecting radiation in a small number of broad wavelength bands
    • allow discrimination of different types of :
    • vegetation,
      • rocks and soils,
      • clear and turbid water, and
      • some man-made materials
  • 16.
    • Quantized incoming energy
    • analyze the numerical values in the bands of a multispectral image
  • 17.
    • High Resolutions Low Resolution
  • 18.
    • Optical System
        • Panchromatic imaging system
        • Multispectral imaging system
        • Super spectral Imaging System
        • Hyper spectral Imaging System
    • RADAR System
    • LiDAR System
  • 19.
    • 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.
  • 20.
    • 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
  • 21.
    • Uses a multi channel detector and records radiation with a narrow range
    • Brightness and color
    • informatics are available
  • 22.
    • Finer spectral feature that capture by the sensors .
  • 23.
    • RAdio Detection And Ranging
    • Object detection system which uses electromagnetic waves determine range, direction or
    • speed
  • 24.
    • Detect the presence of an object at a distance
    • Detect the speed of an object
    • Map something
        • Echo
        • Doppler Shift
  • 25.
    • Light Detection And Ranging
    • Measures distance by sending pulses of laser light that strike and reflect from the surface of earth.
