    dct:description "The UK Compiled Topsoil Dataset (UKTS) is the most extensive topsoil geochemistry dataset for the UK available at the time of release (August 2024). The dataset consists of 82 georeferenced TIFF raster images (GeoTIFF format) with a cell size of 500 x 500 m, displaying the predicted concentrations for 41 chemical elements in UK topsoil and their respective standard error. The dataset 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 UKTS was brought together by combining data from the following sources: i. the British Geological Survey’s (BGS) Geochemical Baseline Survey of the Environment (G-BASE) rural and urban topsoil dataset (which accounts for 76.4% of the topsoil samples included in the UKTS) ii. the Geological Survey of Northern Ireland (GSNI) TellusNI rural and urban topsoil geochemical survey dataset (13.8% of the UKTS samples) iii. the BGS-Rothamsted Research X-ray Fluorescence Spectrometry (XRF) rural soil dataset (RR-BGS XRF), based on sub-samples held at Rothamsted Research from the National Soil Inventory (NSI) of England and Wales sample archive, National Soil Resources Institute, Cranfield University (9.8% of the UKTS samples). An atlas of the compiled topsoil concentrations for the UK is available to download (https://nora.nerc.ac.uk/id/eprint/535963) and all maps are available to view within the UK Soil Observatory website (https://www.ukso.org). The dataset covers 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 ESRI ArcGIS 10.8." ;
