whitebox (version 2.4.0)

wbt_horizon_angle: 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
)

Value

Returns the tool text outputs.

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.
