Using simple kriging to create a quantile map

Simple kriging can produce reliable quantile maps if the input data is normally distributed.

手順:

1. Click the Geostatistical Wizard button on the Geostatistical Analyst toolbar.
2. Select Kriging/CoKriging and choose a dataset and attribute field, then click Next.
3. Select Simple kriging and set the Transformation type to Normal Score and Output Type to Quantile.
4. Type a Quantile value and click Next.
5. Click Next on the Normal Score Transformation dialog box.
6. Specify the desired parameters on the Semivariogram/Covariance Modeling dialog box and click Next.
7. Specify the desired parameters on the Searching Neighborhood dialog box and click Next.
8. Examine the results on the Cross Validation dialog box and click Finish.
9. Click OK on the Method Report dialog box.
