Maximum likelihood parametric reconstruction of forest vertical structure from inclined laser quadrat sampling.
Abstract Forest vertical structure is critical to ecological function, and provides a crucial link to air- and spaceborne remote sensing (including LiDAR), but is difficult to measure from the ground. Laser point quadrat sampling has been suggested as one alternative, but previous statistical approa...
