Using disjunctive kriging to create a prediction map
The data points need to be sampled from a phenomenon that is continuous in space and has a bivariate normal distribution.
Important parameters are appropriate transformation and detrending, covariance/semivariogram model, and search neighborhood.
Steps:
- Click the Geostatistical Wizard button on the Geostatistical Analyst toolbar.
- Click Kriging/CoKriging, choose a dataset and attribute field, then click Next.
- Choose Disjunctive, set Transformation type to Normal Score, then click Next.
- Specify the desired parameters on the Normal Score Transformation dialog box and click Next.
- Specify the desired parameters on the Semivariogram/Covariance Modeling dialog box and click Next.
- Specify the desired parameters on the Searching Neighborhood dialog box and click Next.
- Examine the results on the Cross Validation dialog box and click Finish.
- Click OK on the Method Report dialog box.
