clip plots or polygons form lidar

Description

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

Usage

clip_plots_fusion(
  idxyd = NA,
  dir_las = NA,
  dir_dtm = NA,
  dir_clipdata = "c:\\fusion\\clipdata.exe",
  dir_out = NA,
  out_f = c(".las", ".laz"),
  clipdata_switches = c("/height /shape:1", "")[1],
  n_core = 6,
  temp = "c:\\temp\\clipdata",
  run = T
)

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".
