On the reduction of the ordinary kriging smoothing effect
A simple but novel and applicable approach is proposed to solve the problem of smoothing effect of ordinary kriging estimate which is widely used in mining and earth sciences. It is based on transformation equation in which Z scores are derived from ordinary kriging estimates and then rescaled by the standard deviation of sample data and the sample mean is added to the result. It bears the grea...

متن کاملUsing Ordinary Kriging for the Creation of Scintillation Maps
This paper introduces Ordinary Kriging as a method for the creation of maps of scintillation indices S4 and σφ which could be used to provide the user information on the accuracy of specific receiver-satellite links. Sufficiently accurate scintillation maps, also providing an er‐ ror estimate of the map values, could ultimately lead to their direct implementation in the positioning’s stochastic...
