When using either methods to create a surface from the same set of observations, these surfaces differ from each other.
Visually it can be seen in the differences of the following contours (overlaid; the Red is Ordinary Kringin, Purple is Universal).
What are the main differences in those methods so that they would create different results?
The surfaces were produces using ArcMap's 3D analyst - Default parameters for both tools. I realize that not many people have access to those tools, so I've put online the produced surfaces here. If you want to recreate the contours, in your software use base heights of 9 and step of 2.
