this season. Only the concentration of arable. land 1 in the north makes it ar

image, because spectral signature is very similar to arable land 2. Although 
the cluster diagram (photo 2) shows good spectral separability, these classes An 
do not represent the intended classes entirely. Wet depressions with grassland cre 
are shown to advantage in this season, although rape-seed and green manure will cla 
lead to a slight overestimation of this area. The distribution of broadleaf sha 
forest, types of coniferous forest and sandpits have the indicator values as the

Here too, the classes residential_area and uncovered_soil are not well sepa- UTT 
rated spectrally. A differentiation of grassland areas against loamy arable den: 
land is similarily not possible, since during that season, the latter is mostly o 8 
covered by young growth of cereals or rape seed with very similar spectral 
behavior to grassland. On the other hand, the areas of glacial outwash, due 
to & different crop rotation, are hardly covered by crops during this season, 
so that they are represented quite well by the class uncovered soils.
