Relative aspect — wbt_relative

Calculates relative aspect (relative to a user-specified direction) from an input DEM.

Usage

wbt_relative_aspect(
  dem,
  output,
  azimuth = 0,
  zfactor = NULL,
  wd = NULL,
  verbose_mode = NULL,
  compress_rasters = NULL,
  command_only = FALSE
)

Arguments

dem: Input raster DEM file.
output: Output raster file.
azimuth: Illumination source azimuth.
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.
