Sensor Geometry

Land Geometry

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)
