VEGETATION

 

 

    

   The VEGETATION optical instrument, a wide field of view sensor on board of the SPOT-4 earth observation satellite launched in March 1998, operates in 4 spectral bands :
• Blue, mainly to perform atmospheric corrections
• Red and Near Infrared (NIR), sensitive to the vegetation's photosynthetic activity and cell structure
• Short Wave Infrared (SWIR), sensitive to soil and vegetation moisture content.
Its 1 km spatial resolution is nearly constant across the whole 2,250km corridor it covers, which means that there is almost no distortion on image edges.
