LiDAR for vegetation applications

However, in LiDAR measurements of forests, many of the ‘last return’ points may not penetrate to the ground level: indeed, should the small footprint laser hit a large leaf or branch, there may be essentially no difference between these points. We may term these samples ‘crown-crown’ points. Similarly, some points may be ‘ground-ground’ in that the first pulse, as well as the last ... ................
