Outline of Final Research Achievements

A Quantity of forest biomass was estimated by 3D measurement using aerial photography and ground based LiDAR. The measurement data were converted to voxel model with 10cm resolution. A timber volume was estimated from number of measurement point in each voxel. Suggested method was compared with existing model using tree hight and the diameter at breast height. The residual error showed 2%.
Field survey to sample important plants was carried out 439 points in Shikoku area. Sampled plants were "Ubayuri", "Kuromoji", "Himekozo" and "Ryobu". Autogenous land was extracted spatial analysis using topography, geology and meteorology. The results showed "Ubayuri" had a suitable to habitat in Kochi prefecture. Currently, "Ubayuri" is planting to validate in test field.
