Fig. 2

Selected profile. A selected profile (vertical slice) of 3D raster representing the reconstructed 3D vegetation structure (top) and fragmentation index profile (bottom). The yellow color represents cells which contain lidar points from the original point cloud. The green color represents the reconstructed vegetation. The colors in the bottom profile represent the fragmentation index as described in Fig. 3. Vertical and horizontal scales in this figure are the same. The position of the profile is shown in Fig. 5 in 2D and in Fig. 6 in 3D space
