P.hv.par: Parallel Hemispherical-Voronoi Gap Fraction

In adam-erickson/gapfraction: Functions for processing airborne LiDAR scans of forests

Description

This function is a wrapper that allows you to run P.hv on multiple plots in parallel using multi-core CPUs with snow

Usage

P.hv.par(las = NA, models = "all", thresh.vals = seq(1, 4, 0.5),
  thresh.var = "height", reprojection = NA, pol.deg = 5, azi.deg = 45,
  col = "height", plots = TRUE, plots.each = FALSE, plots.save = FALSE)

Arguments

las	String vector or list of LAS files. Defaults to NA.
models	String vector or list of hemispherical lens models to use. Options include equi-distant ("equidist"), equi-angular ("equiangle"), stereographic ("stereo"), orthographic ("ortho"), or "all". Defaults to "all".
thresh.vals	String vector or list of height thresholds to use. Defaults to 2.
thresh.var	Specifies the LiDAR metric to use for thresholding canopy points. Options include height, intensity, nreturn, and class. Defaults to height.
reprojection	Proj4 projection string to use for reprojection. Defaults to NA.
pol.deg	Specifies the polar resolution for the radial plot lines. Defaults to 5.
azi.deg	Specifies the azimuthal resolution for the radial plot lines. Defaults to 45.
col	Specifies the LiDAR metric to use to color points of first plot in display. Options include height, intensity, nreturn, and class. Defaults to height.
plots	Boolean switch for the interactive display of plots. Defaults to FALSE.
plots.each	Boolean switch for displaying individual of plots. Defaults to FALSE.
plots.save	Boolean switch for the saving of plot files to the las.path folder. Defaults to FALSE.

Value

The results of P.hv.par
