Prerequisites for quantitative utilization of hyperspectral imagery are a physically based radiometric correction and accurate sensor calibration. An operational approach for calibration and validation (Cal/Val) would be the use of permanent test sites, which do not require campaign based reference measurements. In this article we present the Cal/Val results of the airborne hyperspectral imagery collected with AisaEAGLE-II sensor over the permanent Metsähovi remote sensing test field in Finland. Images were radiometrically corrected and reflectance accuracy of images based on both the laboratory and vicarious calibration was evaluated. The accuracy evaluation was based on the reference target reflectance in exact imaging geometry. Laboratory BRDF retrieved reflectance values were scaled with field nadir reflectance measurements acquired during the campaign to match with the imaging conditions. The transferability of the vicarious calibration performed over the Metsähovi was tested with the data taken in a different area a week later. The results indicated that the vicarious calibration improved the results in all evaluated cases. © 2013 IEEE.
