Hi group! I tried to find a way to filter out point cloud points, if they have too big Z difference compared to neighbor points. I couldn't find any transformer, which would do it. I could try using buffering a point, then find the points inside the buffer, then compare the Z with the buffered point and the inside points, but with 70GB of LAS files, I think it's too heavy. Are there any PointCloud related transformers, which could do that? Basically I'm filtering out noise and clouds or errors in Z.

What you're suggesting is basically what I did a long time ago (before the Point Cloud transformers were available)
Have you tried resampling?
