clip plots or polygons form lidar

Description

clip plots or polygons form lidar - requires that one first make a project using project which includes both lidar and dtms

Usage

clip_plots(
  idxyd = NA,
  idxy = NA,
  plot_polys = NA,
  id_field_plots = "plot",
  project_gpkg = NA,
  intersect_gpkg = NA,
  dir_out = NA,
  height = T,
  do_plot = F,
  return = F,
  n_core = 6,
  dir_dtm = NA,
  dir_las = NA,
  skip_existing = T,
  fix_dsm_bug = F
)

Arguments

idxyd	dataframe with point id, x and y coordinates, and circle diameter
idxy	(optional) dataframe with polygon vertices (x,y) organized by point id
plot_polys	(optional) shapefile path, or sp object with plot boundaries
id_field_plots	(optional) in the event that a polygon is provided
project_gpkg	spatial polygons dataframe (intersection between dtm and las tiles)
dir_out	where to send clipped plots
height	T/F subtract the ground
do_plot	T/F make a plot of the intersections
return	T/F return intersectiosn
n_core	number of cores to use in clipping
dir_dtm	in case path to dtms has changed from project
dir_las	in case path to las has changed from project
skip_existing	skip csv files that have been processed already - in case processing was interupted
project	path to spatial polygons dataframe (intersection between dtm and las tiles)
plot_tile_intersect	path to spatial polygons dataframe representing intersection between plots and project

Details

There are three ways to provide the input shapes to this function - either as a list of plot ids, coordinates and plot diameters (4 column data.frame), as a list of vertices organized by plot_id (3 column data.frame), or as a polygon shapefile (path to shapefile) inwich case the plot id field must be specified "id_field_plots".
