Supplementary Data S4 – Modell results spearman rank correlation and alternative bias measure.
Figure S4.1: Additional results experiment 1. Panels A and B show squared spearman rank correlation values for Validation A and B.
Figure S4.2: Additional results experiment 2. Panels A and B show squared spearman rank correlation values for Validation A and B.
Supplementary Data S5 – Influence of selected height and crown diameter buffers on finally obtained DEMs
Fig. S5.1: Example for DSMs of one forest stand calculated from point clouds which were composed using different ranges of height (H1-H5 / 1 to 5 m selection range) and crown diameter buffers (CR1-CR5 / 1 to 5 m selection range) to match the SILVA trees.
Figure S5.2: Number of different trees that were selected to construct the forest stand depending on the selected ranges of height (h = 1-5 m) and crown diameter (cr = 1-5 m). The setting of h = 4 m and cr = 4 m applied in the study is marked with an arrow.
