Title

UK Compiled Topsoil raster dataset (UKTSraster)

Abstract

The UKTSraster consists of 82 Georeferenced TIFF raster images (GeoTIFF format) with a cell size of 500x500 m, displaying the predicted concentrations for 41 chemical elements in UK topsoil and respective standard error. The UKTSraster is based on the geochemical analyses of 57,966 topsoil samples collected between 1978 and 2014 and analysed by X-Ray Fluorescence spectrometry (XRF). The UKTSraster covers all of England, Wales, and Northern Ireland, and the Clyde basin in Scotland. The GeoTIFF raster image maps were produced from the interpolation by ordinary kriging of the concentration values in the source data points, using the geostatistical wizard in the geostatistical analyst toolbox of ArcGIS 10.8 (ESRI®).

Quality and validity

Lineage

The 57,966 topsoil data points of the source data are a combination of data from three main sources, namely the BGS G-BASE rural and urban topsoil data, the GSNI TellusNI rural and urban topsoil data and the RR-BGS XRF, accounting with 76.4%, 13.8 and 9.8% of the source data points respectively. Source data points are unevenly distributed varying from 1 sample per 25 km2 in the RR-BGS XRF to 4 samples per 1 km2 in urban centres sampled by the G-BASE and TellusNI projects. The predicted concentration maps reflect this uneven sampling density with less ‘smooth’ geochemical features in areas of the map where sampling density is higher, given the options made during the ordinary kriging.
