UK Compiled Topsoil raster dataset (UKTSraster)

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®).
