FLAASH Atmospheric Correction of Landsat-8 Image in ENVI

FLAASH Atmospheric Correction of Landsat-8 Image in ENVI is what we've talked about in this video. But let's have some explanation:
➡ The objective of atmospheric correction is to determine true surface reflectance values by removing atmospheric effects from satellite images. Atmospheric correction is arguably the most important part of the pre-processing of satellite remotely sensed data and any omission produces erroneous results.
______
➡ FLAASH is a first-principles atmospheric correction tool that corrects wavelengths in the visible through near-infrared and shortwave infrared regions, up to 3 µm. FLAASH is An option to compute scene-average visibility (aerosol/haze amount). FLAASH uses the most advanced techniques for handling particularly stressing atmospheric conditions, such as the presence of clouds.
