Outline of Final Research Achievements

In this research, possibility of estimating large scale three dimensional structure of plant communities with multi platform lidar and SAR was investigated. Methods for accurate estimation of woody volume, leaf area density and leaf inclination angle of trees were developed based on voxel modeling with lidar measurements. In SAR analysis, it was confirmed that analysis using plant structural information was possible based on decomposition of polarimetric scatter components that depend on plant structure. UAV lidar mounting a small lidar was developed, by which precise 3-D images of plant communities could be obtained. Basic knowledge for estimating large scale structure of plant communities using UAV lidar, portable lidar and SAR could be obtained.
