Danie Krige and Kriging

Throughout his life, Daniel Gerhardus Krige (1919 – 2013) conducted much research into mining and mining engineering. His research led to the creation of the spatial interpolation method known as kriging. This article provides a biography of a Danie Krige, and presents a short overview of geostatistics and kriging.
