航空機LiDARの反射強度を用いた単位照射領域における樹種別の樹冠葉面占有率把握に関する検討

抄録

On this study, it was discuss about possibility of extraction of the leaf area density difference between tree species, such as Japanese walnut, White willow and Robinia pseudoacasia, from LiDAR intensity information. It was calculated canopy leaf area ratio in order to grasp the tree species difference. The canopy leaf area ratio was calculated by effective irradiation area versus unit irradiation area using a reflectance intensity of the airborne LiDAR. The canopy leaf area ratio was a difference in leaf area of a single leaf. Possibility of tree species identification was suggested by difference of the canopy leaf area ratio.
