To produce this "multitemporal" image, three images acquired in September 1991 were superimposed upon one another, each in one of the primary colours. Unexpectedly, instead of a preponderance of greys, all colours were abundantly present. Over the observation period, considerable changes of surface structure and moisture took place. On the ground a field study revealed which colour corresponded to which change: harvested grain shows up in yellow, ground prepared for winter corn red, potato fields white, corn fields green, meadows dark green, and forests in blue. The application of this technique for crop classification and monitoring is obvious.
