Maximum Tree Canopy Height data of Nepal

Leaf Area Index (LAI) generated based on Landsat-8 the OLI cloud free images. To generate tree canopy height map, a density scatter graph between the Geoscience Laser Altimeter System (GLAS) on the Ice, Cloud, and Land Elevation Satellite (ICESat) estimated maximum height and Landsat LAI nearest to the center coordinates of the GLAS shots show a moderate but significant exponential correlation (31.211*LAI0.4593, R2= 0.33, RMSE=13.25 m).

本数据集为基于陆地卫星8号（Landsat-8）运行陆地成像仪（Operational Land Imager, OLI）的无云影像反演得到的叶面积指数（Leaf Area Index, LAI）。为构建林冠高度图，研究以冰、云与陆地高程卫星（Ice, Cloud, and Land Elevation Satellite, ICESat）搭载的地球科学激光测高系统（Geoscience Laser Altimeter System, GLAS）反演得到的最大冠层高度，与最接近GLAS光斑中心坐标的Landsat LAI数据绘制密度散点图，结果显示二者存在中等强度且显著的指数相关关系，拟合公式为31.211×LAI^0.4593，决定系数R²=0.33，均方根误差（Root Mean Square Error, RMSE）为13.25 m。
