does anyone have any experience with lasthin with percentile options?? I have a huge lidar point cloud and I only need 75th percentile and above. I labeled the points which are close to the 75th percentile as class 8 then with using lasheight I labeled low noise(class 7) above that percentile. But I am not sure if that is the correct way or not. While applying lasheight it asks me to state a height. But I don t know what is the height exactly...

You have to run the lasground tool before using lasheight. The lasground tool is used to classify the points as "ground" or "non-ground" for your point cloud. Only then the height of each point can be computed from the TIN generated from the ground points (class 2).
Then you can skip directly to the lasthin and keep all points above the 75% percentile.
