The code supports 2D and 3D ordinary and universal kriging. Standard variogram models (linear, power, spherical, gaussian, exponential) are built in, but custom variogram models can also be used. The ...

The use of spatially predicted air pollution exposures in an epidemiologic analysis can be viewed in a measurement error framework, where the predicted exposures ...

Abstract: Estimating traffic flow states at unmeasured urban locations provides a cost-efficient solution for many ITS applications. In this work, a geostatistical framework, kriging is extended in ...

Abstract: Ionospheric delay is a critical error source for global navigation satellite system (GNSS) users. The kriging method is widely adopted to estimate the ...

With inverse distance weighting and simple kriging, we assumed that the underlying spatial trend was essentially constant, or at least wasn’t determined by external information. This is generally a ...
