get_circle_fit: Computes the 3d alpha shape, volume, surface area, and...

In spatial-mk/tre3d: Antarctic Pinguin Measurements

Description

computes the 2d alpha shape, 2d convex hull a 3D set of points as well as ground diameter and diameter at breast height
To avoid collinearity a small random jitter is added to the points before alpha-shape computation.

Usage

get_circle_fit(
  input_cloud = data.frame(x = runif(20), y = runif(20), z = runif(20)),
  plot_fit = FALSE
)

Arguments

input_cloud	A file or data.frame containing a tree point cloud with x y z. If file, it assumes first three columns to be x y z without header. Futher columns are ignored.
plot_fit	Should the circle fit be plotted. Default to FALSE.

Value

A .txt files containing: CPA, CH, Height, GD, DBH, etc.
