A Residual Trend Surface Approach for Understory Terrain Correction to Estimate Forest Stand Heights Using Spaceborne Stereo Imagery and ICESat-2 Ground Photons

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Forest stand height is a key forest structural metric. Spaceborne stereo imagery can generate a spatially continuous digital surface model (DSM) over large areas; however, inaccurate understory terrain caused by canopy obstruction reduces the estimation ...
