Abstract
A novel reflectance-based approach for radiometric calibration and atmospheric correction of airborne hyperspectral (HRS) data, supervised vicarious calibration (SVC), was proposed by Brook and Ben-Dor in 2011. The present study aimed to validate the SVC method using simultaneously operated several different airborne HRS sensors that acquired data above several selected sites. The general goal is thus to apply a cross-calibration approach to examine the capability and stability of the SVC method. In the current study three sensors were involved in an airborne campaign mission supported by EUFAR under a project entitled ValCalHyp. The AISA-Dual (operated by NERC), AHS and CASI (operated by INTA) acquired data over several selected sites in the south of France (Salon de Province, Marseille, Avignon and Montpellier) on 28 October 2010 between 13:00 and 16:00 UTC.
