Optimal Cross‐Validation Strategies for Selection of Spatial Interpolation Models for the Canadian Forest Fire Weather Index System

open access: yesEarth and Space Science, 2022
The Canadian forest fire weather index (FWI) system requires spatially continuous, gridded weather data for temperature, relative humidity, wind speed, and precipitation.

A Spatial Interpolation of Meteorological Parameters considering Geographic Semantics

open access: yesAdvances in Meteorology, 2020
Spatial interpolation of meteorological parameters, closely related to the earth surface, plays important roles in climatological study. However, most of traditional spatial interpolation methods ignore the geographic semantics of interpolation sample ...

Application of a semivariogram based on a deep neural network to Ordinary Kriging interpolation of elevation data.

open access: yesPLoS ONE, 2022
The Ordinary Kriging method is a common spatial interpolation algorithm in geostatistics. Because the semivariogram required for kriging interpolation greatly influences this process, optimal fitting of the semivariogram is of major significance for ...

Comparative evaluation of interpolation methods for the directivity of musical instruments

open access: yesEURASIP Journal on Audio, Speech, and Music Processing, 2021
Measurements of the directivity of acoustic sound sources must be interpolated in almost all cases, either for spatial upsampling to higher resolution representations of the data, for spatial resampling to another sampling grid, or for use in simulations

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

open access: yes, 2005
Spatial interpolation of rain gauge data is important in forcing of hydrological simulations or evaluation of weather predictions, for example. The spatial density of available data sites is often changing with time.

Enhanced spatial error concealment with directional entropy based interpolation switching [PDF]

open access: yes, 2006
This paper describes a spatial error concealment method that uses edge related information for concealing missing macroblocks in a way that not only preserves existing edges but also avoids introducing new strong ones.

Spatial analysis of precipitation in a high-mountain region: exploring methods with multi-scale topographic predictors and circulation types [PDF]

open access: yesHydrology and Earth System Sciences, 2014
Statistical models of the relationship between precipitation and topography are key elements for the spatial interpolation of rain-gauge measurements in high-mountain regions.

Spatial interpolation of precipitation depending on elevation: Case study of the Skrapež River, Western Serbia [PDF]

open access: yesGlasnik Srpskog Geografskog Društva, 2008
In order to make an adequate basic dataset for a subsequent hydrological research, the study of interpolation of precipitation values from measurement stations (points) to large areas (areas) was done.

A Hybrid Method for Interpolating Missing Data in Heterogeneous Spatio-Temporal Datasets

open access: yesISPRS International Journal of Geo-Information, 2016
Space-time interpolation is widely used to estimate missing or unobserved values in a dataset integrating both spatial and temporal records. Although space-time interpolation plays a key role in space-time modeling, existing methods were mainly developed
