Correlation between features and lodging degree. (a) Point cloud data presented the lodging area and the area without lodging with red and purple, respectively. (b) The tangent plane of the plot. (c) The terrain 3D area (m2), fill volume (m3), fill volume error (m3), cut volume (m3), cut volume error (m3), total volume (m3), and total volume error (m3) for the red and the purple area. (d) Volume estimation for all plots. (e) The error of the lodging index generated by the 6 factors and the true label.
