Using ordinary kriging to create a prediction map
Ordinary kriging assumes an unknown constant mean. The data points need to be sampled from a phenomenon that is continuous in space. Important parameters include an appropriate transformation, a possible detrending surface, covariance/semivariogram models, and search neighborhoods.
Pasos:
- Haga clic en el botón Geostatistical Wizard en la barra de herramientas Geostatistical Analyst.
- Select Kriging/CoKriging, choose a dataset and attribute field, then click Next.
- Choose Ordinary kriging, then 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.Nota:
On the Kriging/CoKriging dialog box, a database file can be used in place of an ArcMap layer by clicking the Browse button and navigating to the desired database file.
