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?

enter image description here

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.

  • This seems very broad. What literature have you reviewed prior to posting? For example, both seem to be mentioned in en.wikipedia.org/wiki/Kriging. Are you able to focus this down to a single question as per the Tour? Even here we have a few posts that look worth reviewing and referencing as prior research: gis.stackexchange.com/search?q=%5Bkriging%5D+universal+ordinary – PolyGeo Nov 22 '15 at 22:22

    You are right; too broad. Hopefully I 've narrowed down a bit. Voting to reopen. – nickves Nov 22 '15 at 23:45
  • Are you using tools from ArcGIS for Desktop, or something else? Not being able to see how your results came about is all that holds me back from re-opening after your edit. – PolyGeo Nov 22 '15 at 23:48

    It shouldn't matter since it's a Question on how these two work, but yes I am. Mostly this Question aims as a reference for people looking for more information on the said methods. And a chance for someone to answer it better than I would. – nickves Nov 22 '15 at 23:54
  • If you are writing this to become Community Wiki, then there is a checkbox for that, and also an algorithm tag that can be used. – PolyGeo Nov 23 '15 at 0:09
