Geomorphons

Description

Computes geomorphon patterns.

Usage

wbt_geomorphons(
  dem,
  output,
  search = 50,
  threshold = 0,
  fdist = 0,
  skip = 0,
  forms = TRUE,
  residuals = FALSE,
  wd = NULL,
  verbose_mode = NULL,
  compress_rasters = NULL,
  command_only = FALSE
)

Arguments

`dem`	Input raster DEM file.
`output`	Output raster file.
`search`	Look up distance (in cells).
`threshold`	Flatness threshold for the classification function (in degrees).
`fdist`	Distance (in cells) to begin reducing the flatness threshold to avoid problems with pseudo-flat lines-of-sight.
`skip`	Distance (in cells) to begin calculating lines-of-sight.
`forms`	Classify geomorphons into 10 common land morphologies, else output ternary pattern.
`residuals`	Convert elevation to residuals of a linear model.
`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`.
