WebMentioning: 4 - A practical physics-based regression method was developed and evaluated for nearly real time estimate of land surface emissivity spectra in 8-14 μm from hyperspectral thermal infrared data. Two spectral emissivity libraries and one atmospheric profile database fully covering all the possible situations for clear sky conditions were … WebFLAASH is a better choice for these scenes. QUAC performs best when the imagery is uniformly illuminated, such as clear-sky conditions or when airborne sensors fly under complete cloud cover. If the imagery contains clouds and cloud shadows, you can mask out the clouds and shadows.
