I have a 3D dataset of lines several lines contain large spikes - like the one in the screen shot and attached template.

I tried using the SpikeRemover but it doesn't seem to work - Does the Spike remover just not work on spike in the Z direction - the documentation doesn't really help identify why it doens't work?

Failing that is there another way to remove points like the (z points which are about 100 meters off from the expected position).

I started going down the line of extracting coordinates and trying to identify them that way but it seems like there must be a better way
