internode_distances: Get internode distances between primary branches from a QSM

In tReeTraits: Calculate Tree Traits from Terrestrial Lidar

Get internode distances between primary branches from a QSM

Description

This function estimates the internode distance between primary branches from a QSM. It filters out all primary branches 'branching_order == 1' calculates their attachment points (Z) to the trunk, and then returns the distances betweent the branches

Usage

internode_distances(qsm, min_diam = 2)

Arguments

qsm	a QSM loaded using '[load_qsm()]'.
min_diam	numeric - minimum diameter (in cm) to include branch

Value

A numeric vector of internode distances (m) between consecutive primary branches that meet the diameter threshold. Returns 'NA' if fewer than two qualifying primary branches are present.

Examples

qsm_file = system.file("extdata", "tree_0744_qsm.txt", package='tReeTraits')
qsm = load_qsm(qsm_file)
inodes = internode_distances(qsm)
print(inodes)
median(inodes)
