lidar_ground_point_filter: Lidar ground point filter

In whitebox: 'WhiteboxTools' R Frontend

Description

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

Usage

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,
  verbose_mode = 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 idenfied 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?.
verbose_mode	Sets verbose mode. If verbose mode is False, tools will not print output messages.

Value

Returns the tool text outputs.
