The availability of multiple processing levels of satellite imagery products, either in the free or commercialized domain, by multi-national government agencies or private companies has made imagery utilization for many applications easier than ever.  Take Sentinel-2 imagery as an example, it is been delivered to the public as multi-level data products. You can get L1c products that only radiometric and geometrically corrected, or higher level L2a which the data has been processed to reflectance unit, furthermore it is already atmospherically corrected. So we don't talk about Top of Atmosphere reflectance anymore, we talk about surface reflectance.  However, all this easiness should not make us became lazy person alright?. It is important that remote sensing users know how to do atmospheric correction either in the practical or theoretical domain. Without deep knowledge of remote sensing theories, all of your image processing and analysis skills cant be trusted in order to get...
