Title
Proceedings of the Symposium on Global and Environmental Monitoring

4 CONCLUSIONS
230
From Table 2, following conclusions were
obtained.
1) Classification accuracies of the
proposed automatic classification method
show almost same value to those of a
conventional method by a skilled opera
tor. The variation of mean accuracies
between the conventional method and the
proposed method is less than 1%.
2) Obtained accuracies by using the
proposed method do not depend used
reference maps. The variation of mean
accuracies among the cases of using three
reference maps is less than 1%.
3) In the case of using conventional
method, several weeks may be needed to
establish similar classification
accuracies. Meanwhile, the proposed
method were carried out with about 15
hours by using HP9000/840 mini-computer.
