Lidar rooftop analysis — wbt_lidar_rooftop

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.

Value

Returns the tool text outputs.
