Current Status and Development Trend in Estimating Forest Structural Parameters with Spaceborne LiDAR
The spaceborne LiDAR measurement system offers a solution by covering remote areas that are challenging to access via airborne systems.This system effectively addresses the technical limitations of optical imaging and synthetic aperture radar measurements,thereby providing a reliable data source for swiftly and accurately obtaining forest structure parameters.However,the existing review on applications of spaceborne LiDAR has a lack of analysis that measures the accuracy of forest structural parameters estimated by spaceborne LiDAR as a whole and the content of the analysis is not systematic.The existing spaceborne LiDAR technology observation system were initially reviewed,and then the applicability of spaceborne LiDAR data estimation for multi-scale forest structure parameters was explored.The current development trends,as well as the existing advantages and disadvantages of satellite-borne LiDAR were also analyzed.Finally,the current challenges and anticipates the future prospects and development directions of spaceborne LiDAR technology were summarized.The research result can serve as a valuable reference for the design and application of spaceborne LiDAR remote sensing satellites in forestry.It was suggested that further research can deepen the in-depth study on the inversion of different forest structure parameters,product systems and standard specifications,accuracy evaluation of forestry applications,and design of LiDAR parameters for forestry.
