Discrete natural neighbour interpolation with uncertainty using cross-validation error-distance fields [PDF]

open access: yesPeerJ Computer Science, 2020
Interpolation techniques provide a method to convert point data of a geographic phenomenon into a continuous field estimate of that phenomenon, and have become a fundamental geocomputational technique of spatial and geographical analysts.

Assessing Spatial Variation and Driving Factors of Available Phosphorus in a Hilly Area (Gaozhou, South China) Using Modeling Approaches and Digital Soil Mapping

open access: yesAgriculture, 2023
Soil fertility plays a crucial role in crop growth, so it is important to study the spatial distribution and variation of soil fertility for agricultural management and decision-making.

Lattice constraints on the thermal photon rate [PDF]

open access: yes, 2016
We estimate the photon production rate from an SU(3) plasma at temperatures of about 1.1Tc and 1.3Tc. Lattice results for the vector current correlator at spatial momenta k ~ (2-6)T are extrapolated to the continuum limit and analyzed with the help of a ...

Distance in spatial interpolation of daily rain gauge data [PDF]

open access: yesHydrology and Earth System Sciences, 2006
Spatial interpolation of rain gauge data is important in forcing of hydrological simulations or evaluation of weather predictions, for example. This paper investigates the application of statistical distance, like one minus common variance of observation

Application of a four-dimensional space fractal interpolation algorithm in grade estimation

open access: yes工程科学学报, 2015
Kriging interpolation is a widely used low-pass filter interpolation method, but it cannot reconstruct the high-frequency, low-frequency and partial information of original information.

Four simplified gradient elasticity models for the simulation of dispersive wave propagation [PDF]

open access: yes, 2008
Gradient elasticity theories can be used to simulate dispersive wave propagation as it occurs in heterogeneous materials. Compared to the second-order partial differential equations of classical elasticity, in its most general format gradient elasticity ...

Spatiotemporal Interpolation for Environmental Modelling

open access: yesSensors, 2016
A variation of the reduction-based approach to spatiotemporal interpolation (STI), in which time is treated independently from the spatial dimensions, is proposed in this paper. We reviewed and compared three widely-used spatial interpolation techniques:

Accuracy of areal interpolation methods for count data

open access: yes, 2015
The combination of several socio-economic data bases originating from different administrative sources collected on several different partitions of a geographic zone of interest into administrative units induces the so called areal interpolation problem.
