get_area_profile: Generate area estimates of tree profile in segments

In tReeTraits: Calculate Tree Traits from Terrestrial Lidar

Generate area estimates of tree profile in segments

Description

This function calculates the area of the tree profile by breaking it into segments of height 'segment_height' and estimating the width of each segement. Area profiles are useful for caluclating total area, but also used to detect crown base height.

Usage

get_area_profile(las, segment_height = 0.25, quantile = c(0.001), angle = 0)

Arguments

las	'LAS' object from 'lidR' package representing individually segmented tree, with the crown labeled.
segment_height	numeric - height of each segment in which to calculate area
quantile	numeric - quantile at which width is measured Values in the interval approaching 0 (e.g., 0.001) are recommended to trim random noise
angle	numeric - angle at which to rotate the point cloud prior to estimating area. Useful in a loop if quantifying mulitple angles

Value

A tibble with columns 'bottom', 'top', 'width', 'area', and 'angle' describing the vertical area profile.
