Using Multispectral Spaceborne Imagery to Assess Mean Tree Height in a Dryland Plantation

Table 1

Comparative statistics for calibration and validation data subsets.

Parameter	Calibration subset			Validation subset
	Range	Average	STD	Range	Average	STD
𝐻𝑡 (m)	5–10	8	1	4–11	9	2
DBH (m)	0.12–0.2	0.16	0.02	0.10–0.19	0.16	0.03
CW (m)	3–5	4	1	3–5	4	1
CC (%)	25–91	56	20	28–90	56	19
TPP	6–10	7	1	7–10	8	2
Age (years)	32–37	35	1.5	30–38	35	2.3

𝐻_𝑡 represents mean tree height; DBH: diameter at breast height; CW: crown width; CC: canopy cover, TPP number of trees per plot, and STD: standard deviation.
