  Modes

  1. SPOT

  15 km x 15 km at nadir, in both PAN and Multispectral bands or at different Roll and Pitch angles, within [-45°,45°] in Roll and [-30°, 30°] in Pitch.

  2. STRIP

  The strip length acquisition capacity can vary from 15 Km to as maximum 3480 Km (depending on the compression ratio).

  3. STEREO

  The length of a stereo strip image in single pass can vary from 15 Km to 410 Km depending on the mean fore/aft Pitch angle.

  4. WIDE AREA

  North-South Wide Areas (2 to 5 Strip), East-West Wide Areas (2 to 4 Strip), Single-pass Wide Area Stereo Image (2 Stereo Strips of 45 km each)

  
  

  Image Levels

  • L0 : Raw Image
  • L1 : Radiometrically corrected image (Detector errors, noise and blur removed image)
  • L2A : Geometrically corrected image (Image created by removing the errors caused by the tilt and orientation of the earth)
  • L2B : The image obtained by georectifying the L2A level image (Projected to the determined ellipsoid model)
  • L3A : Orthophoto image
  • L3B : Orthophoto image produced using Ground Control Point(s) (GCP)
  • L4 : Digital elevation model created from stereo image pairs
  • L5 : Mosaic image
  • L6 : Classified image
