clip_plots_fusion: clip plots or polygons form lidar
In jstrunk001/lasR: Simple lidar reading, processing, viewing

Description Usage Details Value Author(s) See Also Examples

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

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)

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".
