Abstract

E{Z}-kriging is educational software that makes it easier for students without a mathematical background to explore the world of kriging. It is interactive, self-explanatory, and easy to use (hence the name, to be pronounced as 'Easy-kriging'). Last but not least: it is available for free. By dragging points and sliding sliders, students will learn features like:
- the distance effect (a.k.a. Tobler's First Law of Geography);
- the screening effect illustrating that kriging is a non-convex interpolator;
- the declustering effect;
- the effect of aggregation (a.k.a. 'upscaling');
- the effect of the variogram model and its parameters (nugget, sill and range);
- the effect of scaling the variogram;
- the effect of data values and configuration;
- how kriging can be turned into a nearest neighbor interpolator or a local mean interpolator.

The first version of E{Z}-kriging was developed in 2001 for the geostatistics course at Wageningen University. Since 2004, it used to be published on the former AI_GEOSTATS website. Since 2026, it has a DOI.
