I've got many rivers (polylines ZM) with many vertices' errors as you can see in the image above.
Vertices' Z errors are not all equal in height (i.e. they are not all at zero height).
I must create a TIN using these rivers as breaklines.
How can I automate this kind of correction?

I was thinking to use "Add Z information" and "feature to point" to transform each polyline's vertex in a point with it's Z value... then.. I would have to compare all the points with their neighboring and identify those with very large Z difference... and then, assign a medium Z value.
Could it work? How can I do? Suggestions?
Thanks in advance!
Paolo
