wbt_horizon_angle: Horizon angle

In whitebox: 'WhiteboxTools' R Frontend

Horizon angle

Description

Calculates horizon angle (maximum upwind slope) for each grid cell in an input DEM.

Usage

wbt_horizon_angle(
  dem,
  output,
  azimuth = 0,
  max_dist = 100,
  wd = NULL,
  verbose_mode = NULL,
  compress_rasters = NULL,
  command_only = 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. 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.
