For REDD+ (Reduction of Emission from Deforestation and forest Degradation) and the Kyoto Protocol, the methodology for a wide range in a short time forest measurement, high-resolution measurement, LiDAR (Lightning Detection and Ranging) will be a powerful tool. In this study, the interpolation method, low-pass filtering, Local Maximum Filter method, and Watershed method were used to estimate the individual stem. Following the comparison of the estimation result of individual stem using LiDAR vs the measured values, the result of accuracy evaluation is 93%.
