With the focus on new available hyperspectral imaging sensors sensitive within the thermal infrared (TIR) wavelength region, this study is testing the ability of the TIR in deriving soil erosion relevant parameters (e.g. texture, organic carbon content) from soil spectral measurements with the respect to commonly used VNIR-SWIR spectrometers. Therefore a study site was chosen located within an agricultural area in Western Australia, which is suffering from soil loss through wind erosion processes. VNIR-SWIR and TIR soil spectra derived from laboratory measurements using common field instruments were therefore resampled to imaging sensor spectral specifications (HyMAP and TASI-600). Prediction models have been established via multivariate regression analysis techniques to quantitatively estimate the soils’ physical-chemical parameters using signatures from different spectral regions.
