Spatial interpolation of water quality index based on Ordinary kriging and Universal kriging
Geomatics, Natural Hazards and Risk, 2023 Water is a very vital needed substance in order to maintain the important activities of humans. However, contaminated water can transmit diseases such as typhoid, dysentery, diarrhea, cholera and polio.

Application of a semivariogram based on a deep neural network to Ordinary Kriging interpolation of elevation data. [PDF]
PLoS ONE, 2022 The Ordinary Kriging method is a common spatial interpolation algorithm in geostatistics. Because the semivariogram required for kriging interpolation greatly influences this process, optimal fitting of the semivariogram is of major significance for ...

PERBANDINGAN PENDUGAAN METODE ORDINARY KRIGING DAN METODE ORDINARY KRIGING DENGAN TEKNIK JACKKNIFE [PDF]
MAp (Mathematics and Applications) Journal, 2023 Pada analisis spasial jika terdapat data yang memiliki distribusi tidak normal, maka akan menghasilkan prediksi yang kurang baik. Untuk mengatasi hal tersebut digunakan metode ordinary kriging dengan teknik jackknife. Dalam metode ordinary kriging dan ordinary kriging dengan teknik jackknife perlu memperhitungkan semivariogram.

Calculation of Probability Maps Directly from Ordinary Kriging Weights [PDF]
Geologia USP. Série Científica, 2010 Probability maps are useful to analyze ores or contaminants in soils and they are helpful to make a decision duringexploration work. These probability maps are usually derived from the indicator kriging approach.

Pendugaan Metode Ordinary Kriging
Jurnal Penelitian Ilmu Sosial dan Eksakta, 2022 Geostatistika merupakan ilmu yang berfokus pada data spasial. Dalam geostatistika terdapat metode pendugaan untuk menangani variabel yang mempunyai nilai bervariasi dengan berubahnya lokasi atau tempat yang disebut variabel teregionalisasi. Metode pendugaan yang digunakan untuk menangani variabel teregionalisasi disebut metode kriging.
