Gaussian scale space

Description

Uses the fast Gaussian approximation algorithm to produce scaled land-surface parameter measurements from an input DEM.

Usage

wbt_gaussian_scale_space(
  dem,
  output,
  output_zscore,
  output_scale,
  points = NULL,
  sigma = 0.5,
  step = 0.5,
  num_steps = 10,
  lsp = "Slope",
  z_factor = NULL,
  wd = NULL,
  verbose_mode = NULL,
  compress_rasters = NULL,
  command_only = FALSE
)

Arguments

`dem`	Name of the input DEM raster file.
`output`	Name of the output land-surface parameter raster file.
`output_zscore`	Name of the output z-score raster file.
`output_scale`	Name of the output scale raster file.
`points`	Name of the input vector points shapefile.
`sigma`	Initial sigma value (cells).
`step`	Step size as any positive non-zero integer.
`num_steps`	Number of steps.
`lsp`	Output land-surface parameter; one of 'AnisotropyLTP', 'Aspect', 'DiffMeanElev', 'Eastness', 'Elevation', 'Hillshade', 'MeanCurvature', 'Northness', 'PlanCurvature', 'ProfileCurvature', 'Ruggedness', 'Slope', 'TanCurvature', 'TotalCurvature'.
`z_factor`	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`.
