I am using NOAA LiDAR data to experiment with methods in lidR. I want to use the linear
segment_shapes() function to locate powerlines, but some of powerlines are already classified as noise. Using
lidR (preferably) or unlicensed
QGIS how do I reset the classification of these points.
I have used the
classify_noise() function in both the las and catalog format. I can't find a simply way to view classifications.
Otherwise is it possible to tell the function from ch 13 in the lidR textbook to consider all points despite already being classified?
lasfile <- readLAS(here("ch13/central_blvd_palmbeach/91_10/9110/Job648155_26080_91_10.las")) las_denoise <- classify_noise(lasfile, ivf(5,2)) seg_las <- segment_shapes(las_denoise, shp_line(th = 8, k = 15), "linear") plot(seg_las, color = "Classification") writeLAS(seg_las, here("ch13/central_blvd_palmbeach/91_10/9110/seg_las.las"))
I am also having trouble updating the classification based on
segment_shapes() algorithm results.
