Mapping the topsoil pH and humus quality of forest soils in the North Bohemian Jizerské hory Mts. region with ordinary, universal, and regression kriging: cross-validation comparison

open access: yesSoil and Water Research, 2013
North Bohemia belongs to one of the most heavily industrialized and polluted regions in Europe. The enormous acid deposition which culminated in the 1970s has largely contributed to the accelerated acidification process in the soils and consequently to ...

Spatio-Temporal Analysis of Drought Severity Using Drought Indices and Deterministic and Geostatistical Methods (Case Study: Zayandehroud River Basin) [PDF]

open access: yesDesert, 2016
Drought monitoring is a fundamental component of drought risk management. It is normally performed using various drought indices that are effectively continuous functions of rainfall and other hydrometeorological variables.

Universal kriging. [PDF]

open access: yes, 2023
Accurate velocity reconstruction is essential for assessing coronary artery disease. We propose a Gaussian process method to reconstruct the velocity profile using the sparse data of the positron emission particle tracking (PEPT) in a biological ...

Augmenting Geostatistics with Matrix Factorization: A Case Study for House Price Estimation

open access: yesISPRS International Journal of Geo-Information, 2020
Singular value decomposition (SVD) is ubiquitously used in recommendation systems to estimate and predict values based on latent features obtained through matrix factorization.

Enhanced universal kriging for transformed input parameter spaces

open access: yesProbabilistic Engineering Mechanics, 2023
With computational models becoming more expensive and complex, surrogate models have gained increasing attention in many scientific disciplines and are often necessary to conduct sensitivity studies, parameter optimization etc. In the scientific discipline of uncertainty quantification (UQ), model input quantities are often described by probability ...

Regional scale surface of the top of the Variscan basement in the central sector of Italy

open access: yesJournal of Maps, 2023
In this study, we combined regional geology and geostatistical analytical processing to model the top surface of the Variscan basement in Italy. This surface, which is overlain by the pre-Alpine sedimentary cycle (Upper Carboniferous – Permian) followed ...

COMPARISON OF ORDINARY AND UNIVERSAL KRIGING INTERPOLATION TECHNIQUES ON A DEPTH VARIABLE (A CASE OF LINEAR SPATIAL TREND), CASE STUDY OF THE ŠANDROVAC FIELD

open access: yesRudarsko-geološko-naftni Zbornik, 2016
Universal Kriging has not until now been used for mapping of geological data in Croatia. However, it is one of the most frequently used methods of Kriging, probably the most adequate in cases when the input data is marked by a common trend.
