  n_core = 4,
  gridmetrics_path = "c:\\fusion\\gridmetrics64.exe",
  heightbreak = 3,
  minht = NA,
  cellsize = 66,
  first = T,
  intensity = F,
  outlier = c(-5, 400),
  fusion_switches = "/nointensity /first /failnoz",
  xmn = NA,
  xmx = NA,
  ymn = NA,
  ymx = NA,
  temp = "c:\\temp\\run_gridmetrics\\",
  new_dtm_path = c(from = NA, to = NA),
  new_las_path = list(from = NA, to = c(NA, NA), prop = c(0.6, 0.4)),
  skip_existing = T,
  existing_coms = c(NA,
    "C:\\Temp\\run_gridmetrics\\2017Aug17_100740\\all_commands.txt"),

  ...
)

Arguments

n_core	number of corest to run process on
gridmetrics_path	where is gridmetrics.exe (FUSION)
heightbreak	Height break for cover calculation
minht	set minht for gridmetrics.ex
cellsize	output raster resolution
first	T/F use only first returns
intensity	T/F include intensity metrics
outlier	c(-5,500) range of inclusion
fusion_switches	other fusion switches as a string e.g. "/noground"
xmn, xmx, ymn, ymx	set extent for analysis
temp	temp folder to hold batch files for use with gridmetrics.exe
new_dtm_path	= c(from = NA, to = NA) rename input file paths (e.g. files have moved)
new_las_path	= c(from = NA, to = NA) rename input file paths (e.g. files have moved)
skip_existing	skip tiles if they already have output csvs
existing_coms	path to existing batch comamnds, incase processing was interrupted the first time
project_gpkg	polygon file of intersections created by project_make() function
table	output folder name
