The spatial distribution of forest canopy cover is a critical indicator for evaluating the forest productivity and decomposition rates.With the Wangqing Forest Region in Jilin Province of China as the study area,this study first estimated the forest canopy cover using spaceborne Li DAR ICESat-GLAS waveforms and Landsat-TM multispectral images,respectively,and then GLAS data and TM images were combined to further estimate forest canopy cover by using multiple linear regression and BP neural network.The resul...
