An object of class list
of length 7.
An object of class list
of length 7.
extraction: parameters used to extract the point cloud, process it into small sections and compute profiles
road_max_len: maximum size of a processed road. If longer than that it will be split in chunks of equal sizes such as no one is more than this size.
road_max_width: maximum width of a road for metrics measurements
road_buffer: width of a buffer around the road for point-cloud extraction
section_length: length of sections of road for metrics measurements
profile_resolution: resolution of the profiles and DTMs for metrics measurements
constraint: parameters to contraint the road relocation step
confidence The confidence you have on the location of the reference roads. 1 means that the road is 100\ confidence that the reference road is correct and this will help the algorithm. Low values leave more freedom to the algorithm but it becomes also more prone to errors. However this parameter is not very sensitive.
embankments: parameters to detect embankments in the terrain
min_slope: slope (degrees) greater may initiate or terminate the detection of embankments
terrain: parameters to detect road based on the terrain aspect (excluding embankment)
max_sd_ground_points: point belonging on road have a low dispersion on Z. maximum standard deviation to be considered as low dispersion
max_elevation_ground_points: once normalized relatively to the potential road all the points are expected to be at 0. This is the tolerance.
state: parameters to evaluate the state of a section
percentage_veg_thresholds:
drivable_width_thresholds:
