Abstract
The forest has greatly been evaluated from viewpoint of the water resource cultivation. On the evaluation of the water resource cultivation of the forest, it is imperative to grasp the geobaotanical relation between the state of vegetation health as a constituent element of the forest and the geological feature. As a result of comparative analysis of geological distribution with spectral index computed by {50×(Band. 4/Band. 3)+Band. 5} of Landsat TM data, distribution pattern of both is nearly agreed. This spectral index was named “geobaotanical index”. This study proposes the use of the geobaotanical index by satellite data analysis as a possible method of assessing the physical property of cedar-forest soil in Boso Peninsula.
