Export validation results from GA as table

ZachHecht-Leavitt — Tue, 20 Dec 2011 14:48:17 GMT

Greetings,

I see it's possible to export what ESRI calls "cross-validation" results from a kriging interpolation using the "Save cross-validation..." button in the Geostatistical Wizard. However, this button disappears in the validation step (that is, if you chose new data on which to test your "trained" model). I would very much like to export the validation results (NOT the "cross-validation" results). Is this possible? I'm using Indicator Kriging with 9.3.

Thank you for any help!

Zach

You can do this with the GA Layer to Points geoprocessing tool:

Build your model with the training data, then use GA Layer to Points. Supply the kriging geostatistical layer you created with the training data, then give the validation dataset and the z-field with the measured values to compare against.
