Figure 2. Flight stripe side-lap effect detected in (aWaveform Energy (sum of waveform intensities) metric and () Return b) LiDAR point cloud with variable density
Figure 4. Flowchart of the overall process followed to assess  and quantify dissimilarities between pairwise samples
Table 2 shows statistical results for each testing variation carried out, indicating when differences are statistically significant between paired samples, being our target to achieve a greater number of variables with no statistical dissimilarities
Figure 5 displays four different global behaviours: WD and NP differences decrease when voxel size increases; HOME, HTMR, VDR and RWE results improve with 0.5 and 1 m voxel size (except mode); FS has not a clear behaviour, increasing and decreasing differe
