Hello everybody,
 
doing my diploma thesis I am working with SPOT pan data, off-nadir.
Unfortunately I am not quite sure about some parameters listed in the
information sheet from SPOT. I would be very grateful for getting
explanation to the following parameters:
 
-Orientation angle (angle between viewing direction and parallel?)
-Incidence angle (the view off the nadir direction, I suppose ..?)
-azimut of sun (where is the origin for counting the angle?)
-elevation of sun (where starts counting?)
-absolute calibration
 
Thank you very much for your help,
 
best regards,
 
Andrea
