Abstract	This study examined the accuracy of external form assessments of individual trees acquired by high-resolution airborne LiDAR in an urban area. The airborne LiDAR points obtained for the crown surface were extracted using multiple extraction intervals. The spatial accuracy of these points was then verified using the terrestrial LiDAR data. The external form of the tree crown was then reconstructed using voxels. External voxels that include one or more points were extracted as areas in which foliage was distributed. The distribution accuracy of the extracted voxels was verified by comparing with the data against terrestrial LiDAR data. The reasons for voxels not being extracted by the airborne LiDAR were also investigated using the Leaf Area Density in voxels derived from terrestrial LiDAR.
