The Use of LiDAR Terrain Data in Characterizing Surface Roughness and Microtopography

Table 3

Qualitative interpretive table used for visual interpretation. Landforms were delineated using these measurements. For example, Top of Ridge was delineated based on a low value for SD of curvature, a high value for the pit fill metric, a low value for SD of slope, and a low value for the spline.

	Roughness metric
	Top of Ridge	Top Slope	Lower Slope	Valley Bottom	Shale Hill
SD of curvature (1)	Low	High	Medium	High	Low
Pit fill metric (2)	High	Low	Medium	High	Low
SD of slope (3)	Low	High	Medium	High	Low
Spline (4)	Low	High	Medium	High	Low
