| Outline of Final Research Achievements |
I tried to develop the method for creating a wide stand volume map in Japanese cedar and Hinoki cypress plantations using remote sensing techniques. The method is composed of two scale-up processes. First, I developed a method for estimating mean tree height at plot scale precisely using airborne LiDAR data with low point density and then a method for mapping stand volume from the plot scale up to sub regional coverage through an empirical regression model constructed using mean tree height data and stand volume data in the field. Second, I performed modeling the relationship between the stand volume estimated with the LiDAR data and a Landsat data within a test area. The estimation error was approximately 20% of the mean stand volume (ca. 670m3/ha) within the test area. The result showed that the Landsat data would have a high potential ability for estimating stand volume.
