A national-level map of above-ground live woody biomass density for tropical countries at 500m. This dataset was assembled from a combination of co-located field measurements, LiDAR observations, and imagery recorded from the Moderate Resolution Imaging Spectroradiometer (MODIS).
热带国家500米处地面活木生物量密度的国家级地图。这个数据集是由同地的实地测量、LiDAR观测和中分辨率成像光谱仪(MODIS)记录的图像组合而成。
