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.
