Edge contamination — wbt_edge_contamination • whitebox

Identifies grid cells within an input DEM that may be impacted by edge contamination for hydrological applications.

Usage

wbt_edge_contamination(
  dem,
  output,
  flow_type = "mfd",
  zfactor = "",
  wd = NULL,
  verbose_mode = NULL,
  compress_rasters = NULL,
  command_only = FALSE
)

Arguments

dem: Name of the input DEM raster file; must be depressionless.
output: Name of the output raster file.
flow_type: Flow algorithm type, one of 'd8', 'mfd', or 'dinf'.
zfactor: 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.
