Topsoil Vis-NIR Spectral Data from Great Britain Countryside Survey

Visible and near-infrared reflectance spectra from 451 and 306 soil samples collected in Great Britain during 2018-2019. The data were used to predict 23 soil parameters via the Open Spectra Soil Library engine, with a comparative analysis performed on 12 measured soil matrices.

Use Cases

• Predict 23 harmonized soil properties from Vis-NIR spectral reflectance data using the OSSL engine
• Perform comparative analysis between measured soil matrices and their spectral prediction results
• Analyze spectral data from ASD AgricSpec and FOSS DS2500 spectrometers across 350-2500 nm wavelengths
• Model soil parameter relationships using diffuse reflectance spectra from 451 re-quartered fine earth samples

Strengths

• Spectral data from 451 samples using an ASD AgricSpec spectrometer and 306 samples using a FOSS DS2500
• Covers visible (350-780 nm) and near-infrared (780-2500 nm) regions with 1 nm and 0.5 nm resolutions
• Linked to prediction of 23 soil parameters and analysis of 12 measured soil matrices

Limitations

• Sample count reduced from 481 collected to 451 analyzed, introducing potential selection bias
• Data is embargoed until June 30, 2026, restricting immediate access and use
• Specific column schema, file formats, and dataset size are unknown from the provided input
