  dem,
  output,
  azimuth = 0,
  max_dist = 100,
  wd = NULL,
  verbose_mode = FALSE,
  compress_rasters = FALSE
)

Arguments

dem

Input raster DEM file.

output

Output raster file.

azimuth

Azimuth, in degrees.

max_dist

Optional maximum search distance (unspecified if none; in xy units). Minimum value is 5 x cell size.

wd

Changes the working directory.

verbose_mode

Sets verbose mode. If verbose mode is False, tools will not print output messages.

compress_rasters

Sets the flag used by WhiteboxTools to determine whether to use compression for output rasters.
