WebThis study used a commercially available ENVI-FLAASH ® (Fast Line of sight Atmospheric Analysis of Spectral Hypercubes) atmospheric correction module to correct clear-sky Landsat 5 TM imagery acquired for the analysis. However, the validation of FLAASH results (e.g., surface reflectance) was a necessary step before algorithm development and ... WebThe Atmospheric Correction Module provides two atmospheric correction modeling tools for retrieving spectral reflectance from multispectral and hyperspectral radiance images: QUick Atmospheric Correction (QUAC ®) and Fast Line-of-sight Atmospheric Analysis of Spectral Hypercubes (FLAASH ®).
