Contours from raster — wbt_contours_from

Derives a vector contour coverage from a raster surface.

Usage

wbt_contours_from_raster(
  input,
  output,
  interval = 10,
  base = 0,
  smooth = 9,
  tolerance = 10,
  wd = NULL,
  verbose_mode = NULL,
  compress_rasters = NULL,
  command_only = FALSE
)

Arguments

input: Input surface raster file.
output: Output vector contour file.
interval: Contour interval.
base: Base contour height.
smooth: Smoothing filter size (in num. points), e.g. 3, 5, 7, 9, 11.
tolerance: Tolerance factor, in degrees (0-45); determines generalization level.
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.
