Level 0

    Raw image given by the system:
      Used for calibration and the measure of the performances
    5 adjacent bands not superimposed to build the whole field
    Volume for one scene:
      PA: 1.8 Gb
      XS: 450 Mb

Level 1

    Image with the same geometry than the Level 0
    Radiometrically corrected:
      aberrant detectors
      ZIB reconstruction
      ghost images XS AC
      PA restauration
    5 adjacent bands not superimposed to build the whole field
    Volume for one scene: idem level 0
      PA: 1.8 Gb
      XS: 450 Mb

Level Perfect Sensor

    Radiometry:
      idem level 1
      PA + XS fusion
    Geometry:
      PA + XS detectors rectilinear
      attitude smoothed
      perfect dating / orbito
    Product preprocessed (the preprocessings consist in the elimination of all the effects due to Pleiades instrument and the restitution in a perfect sensor geometry) before projection on the ground:
      users interfaces simplified
      localisation accuracy preserved
    Volume for one scene:
      PA alone: 3.6 Gb
      XS alone: 900 Mb
      PA + XS: 18 Gb

Level Orthoimages / Orthoimages Mosaic

    Projection on the ground:
      corrected of relief effets but not of the superstructures
    Coordinates system geographic or cartographic
    Final product dedicated to GIS
    Volume for one scene: idem PS
      PA alone: 3.6 Gb (nadir 50 cm)
      XS alone: 900 Mb (nadir 2 m)
      PA + XS: 18 Gb (nadir 50 cm)
