In whitebox: 'WhiteboxTools' R Frontend

Description

Calculates an FD8 flow accumulation raster from an input DEM.

Usage

fd8_flow_accumulation(dem, output,
  out_type = "specific contributing area", exponent = 1.1,
  threshold = NULL, log = FALSE, clip = FALSE,
  verbose_mode = FALSE)

Arguments

dem	Input raster DEM file.
output	Output raster file.
out_type	Output type; one of 'cells', 'specific contributing area' (default), and 'catchment area'.
exponent	Optional exponent parameter; default is 1.1.
threshold	Optional convergence threshold parameter, in grid cells; default is inifinity.
log	Optional flag to request the output be log-transformed.
clip	Optional flag to request clipping the display max by 1 percent.
verbose_mode	Sets verbose mode. If verbose mode is False, tools will not print output messages.
