Lidar nearest neighbour gridding — wbt_lidar_nearest_neighbour

Grids LiDAR files using nearest-neighbour scheme. When the input/output parameters are not specified, the tool grids all LAS files contained within the working directory.

Usage

wbt_lidar_nearest_neighbour_gridding(
  input,
  output = NULL,
  parameter = "elevation",
  returns = "all",
  resolution = 1,
  radius = 2.5,
  exclude_cls = NULL,
  minz = NULL,
  maxz = NULL,
  wd = NULL,
  verbose_mode = NULL,
  compress_rasters = NULL,
  command_only = FALSE
)

Arguments

input: Input LiDAR file (including extension).
output: Output raster file (including extension).
parameter: Interpolation parameter; options are 'elevation' (default), 'intensity', 'class', 'return_number', 'number_of_returns', 'scan angle', 'rgb', 'user data', 'time'.
returns: Point return types to include; options are 'all' (default), 'last', 'first'.
resolution: Output raster's grid resolution.
radius: Search Radius.
exclude_cls: Optional exclude classes from interpolation; Valid class values range from 0 to 18, based on LAS specifications. Example, --exclude_cls='3,4,5,6,7,18'.
minz: Optional minimum elevation for inclusion in interpolation.
maxz: Optional maximum elevation for inclusion in interpolation.
wd: Changes the working directory. Default: NULL will use the value in WhiteboxTools settings, see wbt_wd() for details.
verbose_mode: Sets verbose mode. If verbose mode is FALSE, tools will not print output messages. Default: NULL will use the value in WhiteboxTools settings, see wbt_verbose() for details.
compress_rasters: Sets the flag used by 'WhiteboxTools' to determine whether to use compression for output rasters. Default: NULL will use the value in WhiteboxTools settings, see wbt_compress_rasters() for details.
command_only: Return command that would be executed by system() rather than running tool. Default: FALSE.

Value

Returns the tool text outputs.
