metrics_lefsky: Canopy volume classes

In ptompalski/lidRmetrics: Point cloud metrics for the lidR package.

Canopy volume classes

Description

Canopy volume classes based on Lefsky et al 1999 (see references), modified. A voxel rerprenetation of a forest stand is divided into four classes including: open gap space, closed gap space, euphotic zone, and oligophotic zone. This function is meant to be used within metrics_voxels.

Usage

metrics_lefsky(x, y, z, n)

Arguments

x, y, z	X, Y, Z coordinate of the voxels
n	Point count inside each voxel. Used to distinguish filled and empty voxels.

Value

Percentage of voxels in each class
