The suggested date of separation and classification of the three summer crops is
between 20 July and 20 August (Fig. 5.26 ). Figure 5.27 illustrates the different
spectral responses of these major crops.
These results are compatible with both ASTER-data and LANDSAT-data, and
it is possible to generalize them with other remotely sensed data that operates
especially in the visible and the near infra-red spectral ranges.
