Description

The classification of forest types investigated by the angles between the slope and the sun. The significance of differences between the means of multispectral scanner data in relation to forest types was tested. Based on the original data, the observed differences between Cryptomeria japonica and Pinus densiflora and between Cryptomeria japonica and hardwood were regarded as significant except for 11th channel data. Using the revised data, the observed differences between Chamaecyparis obtusa and Pinus densiflora or between Chamaecyparis obtusa and hardwood were also regarded as significant. The rate of correct classification by the discriminant function was 55.1% using the original data, and this became 57.6% using the revised data. The rate of correct classification for Cryptomeria japonica and Chamaecyparis obtusa using the original data was almost the same as that obtained using the revised data.
