Experimental programs for geologic classification by geomorphological profiles were developed.
A geomorphological profile indicates undulations and registance of a rock's characteristics, so this is one of the most important factors for the photogeological interpretation.
This study processed by following method.
1) Segmentation of objective area into level ground and mountainous district, further segmentation of mountainous district into several mountains
2) Make geomorphological profile for each mountain, profiles maked for four directions (N-S, E-W, NE-SW, NW-SE) at the length of 1.4 km across the DTM
3) Considered statistical features of profile are following:
relief energy, number of valleys and mountains, fourier transformation, second differential value, and others
4) Classification of geologic units by discriminant analysis
In the result, the method by a geomorphological profile is partially applicable to the geologic classification.
