Three preprocessing levels
- FORMOSAT-2 products are available in 3 preprocessing levels:

  • Level 1A
    Radiometric corrections to remove distortions due to variations in sensitivity of elementary detectors in the imaging sensor.
  • Level 2A
    Radiometric corrections identical to level 1A. Geometric corrections to frame the image in a given map projection (default projection is UTM WGS 84).
  • Ortho
    Radiometric corrections identical to level 1A. Geometric corrections to frame the image in a map projection specified by the user and to remove relief distortions (map and/or control points and digital elevation model supplied by user).
