wbt_feature_preserving_smoothing: Feature preserving smoothing

In whitebox: 'WhiteboxTools' R Frontend

Feature preserving smoothing

Description

Reduces short-scale variation in an input DEM using a modified Sun et al. (2007) algorithm.

Usage

wbt_feature_preserving_smoothing(
  dem,
  output,
  filter = 11,
  norm_diff = 15,
  num_iter = 3,
  max_diff = 0.5,
  zfactor = NULL,
  wd = NULL,
  verbose_mode = NULL,
  compress_rasters = NULL,
  command_only = FALSE
)

Arguments

dem	Input raster DEM file.
output	Output raster file.
filter	Size of the filter kernel.
norm_diff	Maximum difference in normal vectors, in degrees.
num_iter	Number of iterations.
max_diff	Maximum allowable absolute elevation change (optional).
zfactor	Optional multiplier for when the vertical and horizontal units are not the same.
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.
