Vegetation index VI derived from the data in figure 7 and the relation between VI and coverage as computed for the nadir direction. To cope with this problem, usually the pixel-values are corrected by means of a quadratic equation. When crops with different properties show a uniformly distribution pattern over the observed area, this correction is shown to work quite well, but when gradients occur in the observed area, the correction primarily corrects for the gradient itself rather than for the differences in radiation caused by the observation geometry. ion of cover ch differ in eg., the leaf spherical, the ed by crop and ion introduces e.
