Laboratory soil reflectance spectra and Zn, Pb, Cd concentrations (pXRF and ICP-OES) used in hyperspectral soil contamination modelling.

This record contains the laboratory spectral and geochemical reference data of Zn, Pb and Cd used in the study “Hyperspectral Soil Heavy Metal Prediction via Privileged-Informed Residual Correction” (Remote Sensing, 2025, 17(12), 1987; DOI: 10.3390/rs17121987). The dataset supports modelling of Zn, Pb, and Cd concentrations in topsoil using laboratory spectroscopy and provides paired reference concentrations measured by portable XRF (pXRF) and ICP-OES. Airborne hyperspectral imagery used in the study is not included.
