Synchronous retrieval of forest canopy cover by airborn LiDAR and optical remote sensing
Forest canopy cover is retrieved Synchronous by the airborne LiDAR data and SPOT-5 HRG data, using the method of linear spectrum decomposition model combined with Li-Strahler geometric-optical model. First, the airborne LiDAR data is used to retrieve forest parameters and then the proportion of pixel not covered by crown or shadow Kg of each pixel in the sample was calculated using Li-Strahler geometric-optical model, while the linear spectrum decomposition model is used to extract the proportion of pixel not covered by crown or shadow Kg of each pixel in the whole imagery.
