Source: R/terrain_analysis.R
wbt_wetness_index.Rd

Calculates the topographic wetness index, Ln(A / tan(slope)).

Usage

wbt_wetness_index(
  sca,
  slope,
  output,
  wd = NULL,
  verbose_mode = NULL,
  compress_rasters = NULL,
  command_only = FALSE
)

Arguments

sca

Input raster specific contributing area (SCA) file.

slope

Input raster slope file (in degrees).

output

Output raster file.

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.
