Calculate statistics on lascatalog files

Source: R/catalog_clip_polygons.R
catalog_clip_polygons.Rd

his function generates multiple output *.laz files based on input polygons (one file per polygon). The files are named after an attribute in the input polygon dataset.

Usage

catalog_clip_polygons(
  lascatalog,
  input_epsg,
  output_path,
  filename_convention = "{ID}",
  polygons,
  parallel = F,
  n_cores = 2
)

Arguments

lascatalog

object of class lascatalog

input_epsg

character EPSG-code of coordinate system

output_path

character path to folder where the newly generated laz-files will be exported to

filename_convention

character identifying the attribute in the polygon data that should be used to name the output files

polygons

object of class spatial polygons featuring an attribute with the IDs or names of the polygons

parallel

logical of length 1. Should the computation be split over several cores? Defaults to FALSE.

n_cores

numeric of length 1. If parall = TRUE, on how many cores should the computations be run on? Defaults to the value registered in options("cores")[[1]], or, if this is not available, to parallel::detectCores()).

Value

lascatalog
