Idw interpolation — wbt_idw_interpolation • whitebox

Interpolates vector points into a raster surface using an inverse-distance weighted scheme.

Usage

wbt_idw_interpolation(
  input,
  field,
  output,
  use_z = FALSE,
  weight = 2,
  radius = NULL,
  min_points = NULL,
  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?.
weight: IDW weight value.
radius: Search Radius in map units.
min_points: Minimum number of points.
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.
