Creating spatial interpolation surfaces with DHS data

  
No. 11. (2015)

Abstract

Improved understanding of sub-national geographic variation and inequity in demographic and health indicators is increasingly recognized as central to meeting development goals. Data from DHS surveys are critical to monitoring progress in these indicators but are generally not used to support sub-national evaluation below the first-level administrative unit. This study explored the potential of geostatistical approaches for the production of interpolated surfaces from GPS cluster located survey data, and for the prediction of gridded surfaces at 5×5km resolution. The impact of DHS cluster displacement on these interpolated ...

 

A new fully gap-free time series of land surface temperature from MODIS LST data

  
Remote Sensing, Vol. 9, No. 12. (20 December 2017), 1333, https://doi.org/10.3390/rs9121333

Abstract

Temperature time series with high spatial and temporal resolutions are important for several applications. The new MODIS Land Surface Temperature (LST) collection 6 provides numerous improvements compared to collection 5. However, being remotely sensed data in the thermal range, LST shows gaps in cloud-covered areas. We present a novel method to fully reconstruct MODIS daily LST products for central Europe at 1 km resolution and globally, at 3 arc-min. We combined temporal and spatial interpolation, using emissivity and elevation as covariates ...

 

WorldClim 2: new 1-km spatial resolution climate surfaces for global land areas

  
International Journal of Climatology (15 May 2017), https://doi.org/10.1002/joc.5086

Abstract

We created a new dataset of spatially interpolated monthly climate data for global land areas at a very high spatial resolution (approximately 1 km2). We included monthly temperature (minimum, maximum and average), precipitation, solar radiation, vapour pressure and wind speed, aggregated across a target temporal range of 1970–2000, using data from between 9000 and 60 000 weather stations. Weather station data were interpolated using thin-plate splines with covariates including elevation, distance to the coast and three satellite-derived covariates: maximum and minimum land surface ...

This data is provided in an effort to promote the use of geospatial science and applications for sustainable development and resource conservation in the developing world. Digital elevation models (DEM) for the entire globe, covering all of the countries of the world, are available for download on this site. [\n] The ...

 

General variational approach to the interpolation problem

  
Computers & Mathematics with Applications, Vol. 16, No. 12. (1988), pp. 983-992, https://doi.org/10.1016/0898-1221(88)90255-6

Abstract

The Talmi and Gilat variational approach to the interpolation problem in arbitrary dimension is presented together with the corresponding physical model. The connection of this approach to some known spline methods is demonstrated and new interpolation functions are derived for one-, two- and three-dimensional cases. They are designed to be flexible through the use of meaningful parameters and to give good approximations of both the function itself and its derivatives as well. ...

 

Smooth interpolation of scattered data by local thin plate splines

  
Computers & Mathematics with Applications, Vol. 8, No. 4. (1982), pp. 273-281, https://doi.org/10.1016/0898-1221(82)90009-8

Abstract

An algorithm and the corresponding computer program for solution of the scattered data interpolation problem is described. Given points (xk, yk, fk), k = 1,…,N a locally defined function F(x, y) which has the property F(xk, yk) = fk, k = 1,…,N is constructed. The algorithm is based on a weighted sum of locally defined thin plate splines, and yields an interpolation function which is differentiable. The program is available from the author. ...

 

An evaluation of void-filling interpolation methods for SRTM data

  
International Journal of Geographical Information Science, Vol. 21, No. 9. (1 October 2007), pp. 983-1008, https://doi.org/10.1080/13658810601169899

Abstract

The Digital Elevation Model that has been derived from the February 2000 Shuttle Radar Topography Mission (SRTM) has been one of the most important publicly available new spatial data sets in recent years. However, the ‘finished’ grade version of the data (also referred to as Version 2) still contains data voids (some 836,000 km2)—and other anomalies—that prevent immediate use in many applications. These voids can be filled using a range of interpolation algorithms in conjunction with other sources of elevation data, ...

Corrigendum to "Modelling soil erosion at European scale: towards harmonization and reproducibility" published in Nat. Hazards Earth Syst. Sci.,15, 225-245, 2015

  
Natural Hazards and Earth System Science, Vol. 15, No. 2. (16 February 2015), pp. 291-291, https://doi.org/10.5194/nhess-15-291-2015

Abstract

[Excerpt] Two editorial mistakes were found in the article. Both refer to Eq. (2), p. 231 (whose correct version was published in the discussion paper, p. 2652). [\n] The first mistake is related to the operator Ω, which was wrongly rendered with a summation operator (Σ). The editorial notation mistake is also evident by considering the semantics of the RDS (relative distance similarity) statistics. As explained in de Rigo et al. (2013) and Bosco et al. (2013), RDS is defined in [0, 1]. Therefore, a summation operator whose arguments are quantities ...

 

Coverage bias in the HadCRUT4 temperature series and its impact on recent temperature trends

  
Q.J.R. Meteorol. Soc. (1 February 2014), pp. n/a-n/a, https://doi.org/10.1002/qj.2297

Abstract

Incomplete global coverage is a potential source of bias in global temperature reconstructions if the unsampled regions are not uniformly distributed over the planet's surface. The widely used Hadley Centre–Climatic Reseach Unit Version 4 (HadCRUT4) dataset covers on average about 84% of the globe over recent decades, with the unsampled regions being concentrated at the poles and over Africa. Three existing reconstructions with near-global coverage are examined, each suggesting that HadCRUT4 is subject to bias due to its treatment of unobserved ...
