cbh_from_qsm: Crown base height (CBH) extraction from a quantitative...

In spatial-mk/tre3d: Antarctic Pinguin Measurements

Description

Extracts the CBH from a QSM file. QSM file (cyl_data*.txt) must come from TreeQSM 2.30.

Usage

cbh_from_qsm(
  cyl_data = "cyl_data_*.txt",
  min_diameter_m = 0.07,
  max_angle_deg = 60,
  min_branch_length_m = 2
)

Arguments

cyl_data	A file containing a QSM, e.g. cyl_data_*.txt
max_angle_deg	Maximum allowed branch angle (in degree) from vertical tree axis. Default 60.0
min_branch_length_m	Minimum length of a first order branch considered to be first living trunk. Default 2.0
min_diameter	Minimum diameter (in meter) of a first order branch considered to be first living trunk. Default 0.07

Value

CBH in meter. Note that CBH computation sets lowest tree point in z axis to 0.
