Hi there,
I have been using the Geospatial Wizard in the ArcMap 10.4.1 desktop GUI to interpolate rainfall station data with good success. During the process I consult the variograms and adjust parameters accordingly -- however, I noticed that the "optimize" feature in the Geospatial Wizard, which uses cross validation to optimize the kriging parameters, gives me equally accurate results.
I have many many layers that I wish to interpolate and I want to do this in a standalone Python script. However, I can't find any way to "optimize" the parameters like in the Geospatial Wizard, I can only input them manually or use the defaults.
Any luck with this? If I am forced to use Model Builder, does that have the optimize feature?
Thank you.
Solved! Go to Solution.
I found an answer to this question - no you cannot automate kriging optimization.
Are you looking to incorporate this tool?

Hmm yes that must be what the Geospatial Wizard is using under the hood, thank you. I was hoping there would be a function that would cross validate and select the correct parameters like the wizard but I guess that would be too easy. If only the Geospatial Wizard wasn't so opaque.

Eric Krouse's post there does provide a suggestion as how to do it though.
Steve Lynch, Eric Krause any changes in this or is the approach the same?
