| Résumé | Unmanned aerial vehicles with hyperspectral sensors present new opportunities for acquiring imagery in overcast conditions. Under such conditions, the empirical line method, with targets of known reflectance can be used for atmospheric compensation. Therefore, understanding changes in spectral response from lab, to field and UAV conditions is important. We assess four standard reference targets (2%-50% reflectance) that were initially characterized in the laboratory. Then, we assess their reflectance derived from field spectroscopy measurements and UAV hyperspectral imagery under diffuse illumination field conditions. In-scattering from surrounding vegetation and high attenuation of the SWIR were found in field-based spectra. Resampled laboratory spectra show good correspondence with UAV HSI spectra of the panels. |
