Interpolates vector points into a raster surface using a radial basis function scheme.

Usage

wbt_radial_basis_function_interpolation(
  input,
  field,
  output,
  use_z = FALSE,
  radius = NULL,
  min_points = NULL,
  func_type = "ThinPlateSpline",
  poly_order = "none",
  weight = 0.1,
  cell_size = NULL,
  base = NULL,
  wd = NULL,
  verbose_mode = NULL,
  compress_rasters = NULL,
  command_only = FALSE
)

Arguments

input

Input vector points file.

field

Input field name in attribute table.

output

Output raster file.

use_z

Use z-coordinate instead of field?.

radius

Search Radius (in map units).

min_points

Minimum number of points.

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.

cell_size

Optionally specified cell size of output raster. Not used when base raster is specified.

base

Optionally specified input base raster file. Not used when a cell size is specified.

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.
