Abstract
Based on ICESat-2 high-resolution data, the disclosure proposes a method for mapping tree height. The method includes acquiring ICESat-2 LiDAR data, airborne LiDAR data, Sentinel-2 imagery data, and ancillary data within the selected time and target area; preprocessing the Sentinel-2 imagery to calculate spectral feature parameters; performing photon-scale calibration on ICESat-2 LiDAR data, and combining with airborne LiDAR data for spatial-scale calibration to obtain tree height feature parameter; preprocessing the ancillary data and calculating terrain feature parameters and climate feature parameters; inputting the spectral feature parameters, terrain feature parameters, and climate feature parameters as independent variables, and the tree height feature parameter as the dependent variable into a random forest regression model to establish a forest tree height inversion model; and utilizing the forest tree height inversion model to generate forest tree height map at a resolution of 20 meters within the target area.
