[MSD44-P10] Estimation of forest resources by a dual-wavelength imaging LiDAR system
This system includes two new technologies. One is imaging LiDAR with modulating Laser light to measure spatial distribution of forest resource in a footprint. Another is dual-wavelength to detect ground surface with high accuracy. Measuring spatial distribution of forest in a footprint by modulating Laser Light gives us information about canopy height and biomass with high accuracy compared with the former sensor such as ICESat/GLAS. A dual-wavelength is able to detect forest surface and ground surface more correctly than the former sensor. This system can increase measurement accuracy for canopy height on a slope, which is difficult situation for evaluating canopy height by the former systems because the system is able to measure a shape of ground surface in the area of Laser irradiation. One of the objective of this mission is to evaluate canopy height with 1 m accuracy; the accuracy of canopy heitht of ICESat/GLAS was 5 m and that of MOLI will be 3 m.
