Article Title: Evaluating UAV and Handheld LiDAR Point Clouds for Radiative Transfer Modeling Using a Voxel-Based Point Density Proxy

Figure Lengend Snippet: Relationship between voxel size (20, 50, 100, and 200 cm) and correlation coefficient ( r ) between simulated radiance and Sentinel-2 NIR reflectance for each LiDAR sensor. UAV-LiDAR (Explorer and Voyager) maintained relatively high and stable correlations across voxel sizes, whereas HLSs (TrionS1 and Hovermap-ST) showed a marked decline in correlation at coarsest voxel resolution (200 cm).
Article Snippet: Four different LiDAR sensors were employed to capture forest structural information: two UAV-LiDAR (Explorer and Voyager, YellowScan SAS, Saint-Clément-de-Rivière, France) and two HLSs (Hovermap-ST, Emesent Pty Ltd., Milton, QLD, Australia; Trion S1, FJD Dynamics, Singapore).
