Figs. 3 and 4 confirm that these 27 clusters have a high degree of seperatability: none of the final classes has a similar phenology. The
ISODATA clustering technique met the expected goal to separate
phenological differences such as the start of growing season, the
end of the growing season and growing length of a particular crop.
The two peaks in one annual cycle (Fig. 3) represent multi-cropping
systems with intensive irrigation practices. The start and end of
these peaks distinguish major crop types grown in the study area.
