Dear all,

I have a problem with the function Kriging. I've searched on the internet and on these forums but I can't seem to find the solution.
I have a polygon shapefile and a point shapefile. The points have elevation values. I want to make a surface using kriging, based on the elevation values from the points, and extended over the polygon shapefile. The problem is that the kriging functions creates a 'horizontal' rectangle while my polygon has a different shape.
I want the new surface, created with the kriging function, to extend over the existing polygon. Anyone knows how to do this?
My workspace exists of many of these polygons with points shapefiles next to eachother and I want to make a surface overview of the elevation values.

See the attachment for a simplified image of the problem.

Have you set your Processing extent = to that of the polygon?

This is done via the Environment.

Thanks, that works!

Is there anyway I can use the Processing Extent as a variable in the Modelbuilder?
Edit: I already found how to this, nevermind 🙂
