This interactive demo shows the Kriging system and its solution based on N samples in two-dimensions. The central location, which is located at the middle point on the plane (0,0), will be estimated. The cartesian plane has limits between -100.0 and 100.0 in both x and y. I will improve the display of the plane soon.

You can generate from 2 to 6 samples. Move any sample around the plane and see the changes on distances, kriging (ordinary) system, weights, estimated value and kriging variance.

Number of sample points to generate (between 2 and 6):

Minimum and maximum value from uniform distribution:
