I have a point a nd a polygon vector shape (shapes) which I want to interpolate by using the saga tool "Ordinary Kriging". I always get the following error message:
Oooops! The following output layers could not be open
Grid: C:\Temp\processing\cba78634d19046f9bd0fa87f1156dac2\USERGRID.tif
The above files could not be opened, which probably indicates that they were not correctly produced by the executed algorithm
Checking the log information might help you see why those layers were not created as expected
This algorithm requires SAGA to be run. A test to check if SAGA is correctly installed and configured in your system has been performed, with the following result:
SAGA seems to be correctly installed and configured
This is the log:
