How to set a minimum value for kriging and cokriging?

BethBrockett

Hello everyone

 

I wonder if anyone can advise how I can set a minimum value for an interpolated surface created by kriging and cokriging? (I want to set a minimum predicted value of zero).  I am using the Geostatistical Analyst Wizard to create my model specifications - but may be able to get the modification scripted if necessary.

 

Many thanks, Beth

In most cases there should not be a problem. You can, however, see how well or how badly the data are being transformed. On the NormalSoreTransformation page in the Wizard change to a Cumulative graph and you’ll see if there is a large deviation or not.

The Wizard automatically does the back-transform so you don’t have to do that yourself.
