I have some point clouds from mobile terrestrial laser scanning of circular sampling plots in woodland environments. I am interested in studying the structural complexity of the woodland understorey. I have used the
clip_circle() function to crop the point clouds to the 15 metre radius of the sampling plot.
Now, I would like to horizontally slice the point cloud so that I can obtain the first two metres of points from the woodland floor. Therefore, I would like to extract a 15-metre radius cylinder of two metres depth, positioned on the floor.
I managed to do this in CloudCompare and reimport the cloud back into R like this:
However I would like to do the whole pipeline in R to save time when I have more clouds to process.
