Lidar ground point filter

Description

Identifies ground points within LiDAR dataset using a slope-based method.

Usage

wbt_lidar_ground_point_filter(
  input,
  output,
  radius = 2,
  min_neighbours = 0,
  slope_threshold = 45,
  height_threshold = 1,
  classify = TRUE,
  slope_norm = TRUE,
  height_above_ground = FALSE,
  wd = NULL,
  verbose_mode = NULL,
  compress_rasters = NULL,
  command_only = FALSE
)

Arguments

`input`	Input LiDAR file.
`output`	Output LiDAR file.
`radius`	Search Radius.
`min_neighbours`	The minimum number of neighbouring points within search areas. If fewer points than this threshold are identified during the fixed-radius search, a subsequent kNN search is performed to identify the k number of neighbours.
`slope_threshold`	Maximum inter-point slope to be considered an off-terrain point.
`height_threshold`	Inter-point height difference to be considered an off-terrain point.
`classify`	Classify points as ground (2) or off-ground (1).
`slope_norm`	Perform initial ground slope normalization?.
`height_above_ground`	Transform output to height above average ground elevation?.
`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`.
