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.
