Lidar rooftop analysis

Description

Identifies roof segments in a LiDAR point cloud.

Usage

wbt_lidar_rooftop_analysis(
  buildings,
  output,
  input = NULL,
  radius = 2,
  num_iter = 50,
  num_samples = 10,
  threshold = 0.15,
  model_size = 15,
  max_slope = 65,
  norm_diff = 10,
  azimuth = 180,
  altitude = 30,
  wd = NULL,
  verbose_mode = NULL,
  compress_rasters = NULL,
  command_only = FALSE
)

Arguments

`buildings`	Input vector build footprint polygons file.
`output`	Output vector polygon file.
`input`	Input LiDAR file.
`radius`	Search Radius.
`num_iter`	Number of iterations.
`num_samples`	Number of sample points on which to build the model.
`threshold`	Threshold used to determine inlier points (in elevation units).
`model_size`	Acceptable model size, in points.
`max_slope`	Maximum planar slope, in degrees.
`norm_diff`	Maximum difference in normal vectors, in degrees.
`azimuth`	Illumination source azimuth, in degrees.
`altitude`	Illumination source altitude in degrees.
`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`.
