From Kriging to contour plot

pangcc
Dear Experts,

Is ILWIS 3.0 contain a function to output Kriging results (i.e. semi-variogram) to contour plot?  

I have obtained this nice little semi-variogram (as attached), and I would like to output the point data as an interpolated contour plot based on this Kriging result.  Is there a way to do that?  Please advice.



Thanks!

Best regards,
Clement

Hi!

There is a page in the ILWIS Help that describes the steps to perform
Kriging
The page's title is "How to use Kriging", and you can navigate there as
follows:
In the ILWIS window, click Help->How To...->use...->Kriging
I can see that you have reached Step 2 on this page, and perhaps Step 3
(adding a Semi-variogram Model to the Graph, with sill, range and
nugget, or sill slope and power, depending on the model).
Paragraph 3.3 suggests how to verify the fitting of your model.
When you are satisfied, you will have a kriging method, a semivariogram
model, and the sill, range, nugget values or sill, slope, power values,
in order to proceed with Step 4 to actually proceed with the Kriging
interpolation and get an interpolated raster map.

Cheers,
