Geomorphons

Source: R/terrain_analysis.R
wbt_geomorphons.Rd

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.

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.

Value

Returns the tool text outputs.
