Kriging Explorer
Adjust the influence range and distance power to interpolate nitrate concentrations between wells. Hover each well to see its influence radius.
How far each well's influence extends — the kriging "range" parameter. Larger = smoother, but more likely to blur real gradients.
How steeply influence falls with distance. High power = only the nearest wells contribute; low power = distant wells still matter.

Hover a well to see its influence radius. The colour surface predicts nitrate concentration between wells — this is spatial interpolation. The GW-14 hotspot (northeast) drives the red region around the agricultural zone.
