lidar_ground_point_filter {whitebox} | R Documentation |
Identifies ground points within LiDAR dataset using a slope-based method.
lidar_ground_point_filter(input, output, radius = 2, min_neighbours = 0, slope_threshold = 45, height_threshold = 1, classify = TRUE, slope_norm = TRUE, verbose_mode = FALSE)
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?. |
verbose_mode |
Sets verbose mode. If verbose mode is False, tools will not print output messages. |
Returns the tool text outputs.
