Leaf area density (LAD) profile of zelkova trees was estimated by combining helicopter-borne and portable lidar data based on voxel-based canopy profiling (VCP) method. In this VCP-method, 3-D point cloud data of the trees in the measurement plot were collected from airborne and portable scanning lidar. These data were registered into a single-point cloud date set with a common coordinate system, and then converted into a voxel-based 3-D model that reproduced the tree precisely, including within the canopy. This precise voxel model allowed the LAD of these trees to be computed by direct counting of the beam-contact frequency in each layer. Afterwards, linear interpolation was applied to the underestimated parts of the LAD profile. Root mean square error of the best LAD estimations was 0.20 m2m-3.
