联合空地LiDAR的红树林单木生长参数提取方法 - 遥感学报
Nov 3, 2023 · Aiming at the problem that it is difficult to fully describe the 3D structure of mangroves using only airborne LiDAR, the research on the method of mangrove single tree segmentation and parameter extraction based on combinational Airborne-Ground LiDAR helps to explore the applicability of LiDAR in the protection of coastal ecosystems, and provid...
Individual mangrove tree measurement using UAV-based LiDAR …
Mar 15, 2019 · Specifically, we aim to detect and measure tree height (TH) and crown diameter (CD) of each mangrove tree, and analyze the impact of crown clumping density and spatial resolution on mangrove ITDD. To this end, we combined the variable window filtering method and marker controlled watershed segmentation algorithm, and successfully delineated 46. ...
Mangrove tree distribution - Wikipedia
Global mangrove distributions have fluctuated throughout human and geological history. The area covered by mangroves is influenced by a complex interaction between land position, rainfall hydrology, sea level, sedimentation, subsidence, storms and pest-predator relationships [2][3]).
Segmentation of individual mangrove trees using UAV-based …
Nov 1, 2023 · In this study, we systematically analysed the factors influencing mangrove single-tree segmentation, such as data source, image resolution, segmentation algorithm, and stand density, based on UAV LiDAR data.
