Google Earth Engine——地球科学激光测高系统（GLAS）的空间激光雷达数据（2005年）和辅助地理空间数据融合的全球树木高度数据集

This dataset represents global tree heights based on a fusion of spaceborne-lidar data (2005) from the Geoscience Laser Altimeter System (GLAS) and ancillary geospatial data. See [Simard et al. (2011)] (​​Mapping forest canopy height globally with spaceborne lidar - Simard - 2011 - Journal of Geophysical Research: Biogeosciences - Wiley Online Library​​) for details.

该数据集代表了基于地球科学激光测高系统（GLAS）的空间激光雷达数据（2005年）和辅助地理空间数据融合的全球树木高度。详见[Simard等人（2011）]（https://agupubs.onlinelibrary.wiley.com/doi/abs/10.1029/2011JG001708）。
