Enhancing Indoor Air Quality Estimation: A Spatially Aware Interpolation Scheme

open access: yesISPRS International Journal of Geo-Information, 2023
The comprehensive and accurate assessment of the indoor air quality (IAQ) in large spaces, such as offices or multipurpose facilities, is essential for IAQ management.

Information Diffusion Interpolation Model Based on the PSO-CV Algorithm and Its Application on Source Regions of the Yellow River

open access: yesRenmin Zhujiang, 2021
The spatial interpolation based on the limited observation data of precipitation stations is an effective means to explore the spatial characteristics of precipitation.This paper briefly introduces a spatial interpolation model based on the information ...

Spatiotemporal super-resolution for low bitrate H.264 video [PDF]

open access: yes, 2010
Super-resolution and frame interpolation enhance low resolution low-framerate videos. Such techniques are especially important for limited bandwidth communications. This paper proposes a novel technique to up-scale videos compressed with H.264 at low bit-

A statistical gap-filling method to interpolate global monthly surface ocean carbon dioxide data [PDF]

open access: yes, 2015
We have developed a statistical gap-filling method adapted to the specific coverage and prop-erties of observed fugacity of surface ocean CO2(fCO2). We have used this method to interpolate the Sur-face Ocean CO2Atlas (SOCAT) v2 database on a 2.5832.58 ...

Imputation of spatial air quality data using gis-spline and the index of agreement in sparse urban monitoring networks

open access: yesRevista Facultad de Ingeniería Universidad de Antioquia, 2015
This paper presents a procedure to address the lack of spatial air quality data in urban areas, based on the use of Geographic Information Systems (GIS) and spatial interpolation techniques as an alternative to conventional methods of statistical ...

Spatial snow water equivalent estimation for mountainous areas using wireless-sensor networks and remote-sensing products [PDF]

open access: yes, 2018
We developed an approach to estimate snow water equivalent (SWE) through interpolation of spatially representative point measurements using a k-nearest neighbors (k-NN) algorithm and historical spatial SWE data.

Spatial Interpolation

open access: yes
The theory and practical application of techniques of statistical interpolation are studied in this thesis, and new developments in multivariate spatial interpolation and the design of sampling plans are discussed. Several applications to studies in soil science are presented.Sampling strategies for collecting spatial data (both the number of ...

A comprehensive assessment of spatial interpolation methods for the groundwater quality evaluation of Lahore, Punjab, Pakistan

open access: yesNUST Journal of Engineering Sciences, 2017
Spatial interpolation is commonly used to generate water quality surfaces, but different spatial interpolation methods yield different surfaces from the same data.
