Feature preserving smoothing

Source: R/terrain_analysis.R
wbt_feature_preserving_smoothing.Rd

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.
