wbt_lidar_rooftop_analysis {whitebox}

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.

Value

Returns the tool text outputs.
