tree_metrics: Tree Metrics

In rTwig: Realistic Quantitative Structure Models

Tree Metrics

Description

Calculates tree metrics from a QSM

Usage

tree_metrics(cylinder)

Arguments

cylinder

QSM cylinder data frame

Details

Calculates detailed tree, branch, and segment metrics from a QSM. The outputs include all of the standard outputs from TreeQSM, and also additional variables, including, but not limited to, growth length, reverse branch order, branch segment or node relationships, and distances from twigs and the base of the tree, across various distribution metrics. Also included is a simulated point cloud of the tree, based on the QSM cylinder radii. When corrected with Real Twig, this allow for the testing and validation of point cloud diameter overestimation throughout the tree.

Value

Returns a list of tree metric data frames and synthetic point cloud
