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.
