Kriging: a method of interpolation for geographical information systems

open access: yesInternational journal of geographical information systems, 1990
Geographical information systems could be improved by adding procedures for geostatistical spatial analysis to existing facilities. Most traditional methods of interpolation are based on mathematical as distinct from stochastic models of spatial variation.

Probabilistic modelling of geotechnical conditions for offshore wind turbine support structures [PDF]

open access: yes, 2014
The geotechnical conditions of the soil can fluctuate greatly across the wind farm. This is an issue since geotechnical modelling is the base of the structural design of an offshore wind farm, and the efficient installation of the wind turbines ...

Super-Resolution Reconstruction of Depth Image Based on Kriging Interpolation

open access: yesApplied Sciences, 2023
The super-resolution of depth images is a research hotspot. In this study, the classical Kriging algorithm is applied to the spatial interpolation of depth images, together with the fractional-order differential method for edge recognition, to realise ...

Random Forest Spatial Interpolation

open access: yesRemote Sensing, 2020
For many decades, kriging and deterministic interpolation techniques, such as inverse distance weighting and nearest neighbour interpolation, have been the most popular spatial interpolation techniques.

Comparative suitability of ordinary kriging and Inverse Distance Weighted interpolation for indicating intactness gradients on threatened savannah woodland and forest stands

open access: yesEnvironmental and Sustainability Indicators, 2021
Mapping spatial variations in tree density and woody species diversity, as indicators of intactness of tropical forests and woodlands, is potentially useful to nature conservation managers.

Kriging interpolating cosmic velocity field [PDF]

open access: yesPhysical Review D, 2015
[abridged] Volume-weighted statistics of large scale peculiar velocity is preferred by peculiar velocity cosmology, since it is free of uncertainties of galaxy density bias entangled in mass-weighted statistics. However, measuring the volume-weighted velocity statistics from galaxy (halo/simulation particle) velocity data is challenging.

A Method of Camera Calibration Based on Kriging Interpolation

open access: yesIEEE Access, 2021
The basis of visual measurement is camera calibration. In the traditional calibration method, the radial and tangential distortion models usually are adopted. Because of the randomness of lens distortion, the above fixed form distortion model cannot accurately express the distortion distribution. To solve the above problems, a calibration method with a

Kriging Interpolation in Modelling Tropospheric Wet Delay [PDF]

open access: yesAtmosphere, 2020
This contribution implements the Kriging interpolation in predicting the tropospheric wet delays using global navigation satellite system networks. The predicted tropospheric delays can be used in strengthening the precise point positioning models and numerical weather prediction models.

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.
