Forest canopy height extraction in rugged areas with ICESAT/GLAS data
Geoscience Laser Altimeter System data have been widely used in forest canopy height
extraction. It is still challenging over rugged areas. In this paper, we propose a forest canopy
height extraction method consisting of the Savitzky-Golay filter and fitting, Sigbeg
determination based on the fitting results, and slope correction for rugged areas, particularly
for slopes ranging from 5° to 15°. The method was applied to both the Xinlin Forest, China,
and Santa Rosa National Park, Costa Rica. The performance of this method was validated …
