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.

Value

Returns the tool text outputs.
