A geometry-aligned and elevation-guided U-Net for canopy mapping of Populus euphratica trees using UAV LiDAR and multispectral imagery
ABSTRACT Accurate plot-scale canopy mapping of Populus euphratica trees in desert riparian forests remains challenging because highly reflective bare soil, mixed shrubs and fragmented crowns often cause severe spectral confusion. In addition, residual local inconsistencies between uncrewed aerial vehicle (UAV) multispe...
