Lidar rbf interpolation

Description

Interpolates LAS files using a radial basis function (RBF) scheme. When the input/output parameters are not specified, the tool interpolates all LAS files contained within the working directory.

Usage

wbt_lidar_rbf_interpolation(
  input,
  output = NULL,
  parameter = "elevation",
  returns = "all",
  resolution = 1,
  num_points = 20,
  exclude_cls = NULL,
  minz = NULL,
  maxz = NULL,
  func_type = "ThinPlateSpline",
  poly_order = "none",
  weight = 5,
  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'.

returns

Point return types to include; options are 'all' (default), 'last', 'first'.

resolution

Output raster's grid resolution.

num_points

Number of points.

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.

func_type

Radial basis function type; options are 'ThinPlateSpline' (default), 'PolyHarmonic', 'Gaussian', 'MultiQuadric', 'InverseMultiQuadric'.

poly_order

Polynomial order; options are 'none' (default), 'constant', 'affine'.

weight

Weight parameter used in basis function.

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.
