Comparing linear and non-linear kriging for grade prediction and ore/waste classification in mineral deposits
(Taylor and Francis Ltd., 2019)
© 2017, © 2017 Informa UK Limited, trading as Taylor & Francis Group. Ore/waste classification and economic evaluations of mineral deposits rely on the grade of elements of interest, which must be predicted as accurately ...

Ordinary multigaussian kriging for mapping conditional probabilities of soil properties
(ELSEVIER, 2006-05)
This paper addresses the problem of assessing the risk of deficiency or excess of a soil property at unsampled locations, and more generally of estimating a function of such a property given the information monitored at ...
Comparación de los interpoladores IDW y Kriging en la variación espacial de pH, Ca, CICE y P del suelo
(2007-12-13)
Con el objetivo de comparar los interpoladores Kriging y el IDW (Inverse Distance Weighting), por ser los más utilizados en los estudios de análisis de la variación espacial, en un área de 2 467 m2 se procedió a georeferenciar ...
Geostatistical estimation of mineral resources with soft geological boundaries: a comparative study
(SOUTH AFRICAN INST MINING METALLURGY, 2006-08)
Mineral resource evaluation requires defining geological domains that differentiate the types of mineralogy, alteration and lithology. Usual practice is to consider the domain boundaries as hard, i.e. data from across the ...
Multigaussian kriging for point-support estimation: incorporating constraints on the sum of the kriging weights
(SPRINGER, 2006-01)
In the geostatistical analysis of regionalized data, the practitioner may not be interested in mapping the unsampled values of the variable that has been monitored, but in assessing the risk that these values exceed or ...
Técnicas geoestatísticas aplicadas ao mapeamento de variáveis limnológicas e quantificação da incerteza associada às estimativas
(2015-01-01)
Aim: This study aimed to map the concentrations of limnological variables in a reservoir employing semivariogram geostatistical techniques and Kriging estimates for unsampled locations, as well as the uncertainty calculation ...
Multi-Gaussian kriging: a practice to enhance delineation of mineralized zones by Concentration–Volume fractal model in Dardevey iron ore deposit, SE Iran
(Elsevier, 2015)
The purpose of this study is to identify the effect of ordinary and simple multi-Gaussian kriging (oMK, sMK) estimation methods for the delineation of iron mineralized zones based on subsurface data using Concentration-Volume ...
SRTM resample with short distance-low nugget kriging
(TAYLOR & FRANCIS LTD, 2008)
The shuttle radar topography mission (SRTM), was flow on the space shuttle Endeavour in February 2000, with the objective of acquiring a digital elevation model of all land between 60 degrees north latitude and 56 degrees ...
