Embankment mapping

Description

Maps and/or removes road embankments from an input fine-resolution DEM.

Usage

wbt_embankment_mapping(
  dem,
  road_vec,
  output,
  search_dist = 2.5,
  min_road_width = 6,
  typical_width = 30,
  max_height = 2,
  max_width = 60,
  max_increment = 0.05,
  spillout_slope = 4,
  remove_embankments = FALSE,
  wd = NULL,
  verbose_mode = NULL,
  compress_rasters = NULL,
  command_only = FALSE
)

Arguments

`dem`	Input raster DEM file.
`road_vec`	Input vector polygons file.
`output`	Output raster file.
`search_dist`	Search distance used to reposition transportation vectors onto road embankments (in map units).
`min_road_width`	Minimum road width; this is the width of the paved road surface (in map units).
`typical_width`	Typical embankment width; this is the maximum width of an embankment with roadside ditches (in map units).
`max_height`	Typical embankment maximum height; this is the height a typical embankment with roadside ditches (in map units).
`max_width`	Maximum embankment width, typically where embankments traverse steep-sided valleys (in map units).
`max_increment`	Maximum upwards increment between neighbouring cells on an embankment (in elevation units).
`spillout_slope`	Spillout slope (in degrees).
`remove_embankments`	Optional flag indicating whether to output a DEM with embankments removed (true) or an embankment raster map (false).
`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`.
