How to define the path which I surveyed 4 times?

I did a kinematic survey of a path. I automatically collected data with GPS every second while I was walking on the path (walking speed is not constant). I did 8 repetitions on the same path. Now I have 8 different point clouds for the same path. How can I define one point cloud from 8 point clouds?

The image shows how the points look in QGIS. I don't have enough knowledge to figure it out.

• It is unclear what you want to do. What do you mean by "define one Point cloud"? You want to combine your 8 Point layers into one? – BERA Dec 12 '17 at 14:05
• I want to create a point layer which is average of my 8 point layer. – Can Delice Dec 12 '17 at 15:45
• I think you should digitize the path manually – BERA Dec 12 '17 at 17:22
• do you want to average XYs (horizontal) and Z (vertical)? If that is all the points you have, I wonder if that is something you could do with field calcaulator... make each iteration of X1, Y1, Z1, : X2, Y2, Z2 etc of the path a field and calculate the average of the Xs, Ys, Zs to create your new layer of averages. – ZrSiO4 Dec 12 '17 at 20:32
