Vegetation height is one of the leading dimensions of ecological variations among tree species and is central to ecosystem functioning [1]. Since its launch in 2003, GLAS (Geoscience Laser Altimeter System) on board ICESat (Ice, Cloud,and land Elevation Satellite) has produced unprecedented dataset at the global scale [2]. However, the challenge to retrieve canopy height from large-footprint sa...

Gaussian decomposition has been used to extract terrain elevation from waveforms of the satellite lidar GLAS (Geoscience Laser Altimeter System), on board ICESat (Ice, Cloud, and land Elevation Satellite). The common assumption is that one of the extracted Gaussian peaks, especially the lowest one, corresponds to the ground. However, Gaussian decomposition is usually complicated due to the broa...
