There is potential to use soil ·-proximal and remote sensing derived spectra concomitantly to develop soil organic carbon (SOC) models. Yet mixing spectral data from different sources and technologies to improve soil models is still in its infancy. The objective of this study was to incorporate soil spectral features indicative of SOC from laboratory visible near-infrared reflectance (vis-NlR) spectra and incorporate them with remote sensing (RS) images to improve predictions of top SOC in the Skjem river catchment, Denmark. The secondary objective was to improve prediction results by separately calibrating samples from upland and wetland. We hypbthesize that final prediction accuracy is significantly improved by incorporatin1 laboratory vis-NlR images upscaled from point-based spectra to catchment scale and RS data for topsoil SOC spatial modeling.
