Measuring diameter at breast height (DBH) is an essential but laborious task in the traditional forest inventory; it motivates people to develop alternative methods based on remote sensing technologies. In recent years, structure from motion (SfM) photogrammetry has drawn researchers’ attention surveying for its economy and high precision as light detection ranging (LiDAR) are always expensive....

Abstract. Floating lidar systems (FLSs) are widely used for offshore wind site assessment, and their measurements show good agreement when compared to trusted reference sources. However, some influence of motion on mean speed data from FLS has be assumed but could not have been quantified with experimental methods yet because the involved uncertainties larger than expected impact motion. This s...
