Surface Reflectance orthorectified imagery from CBERS-4, Landsat-8 and Sentinel-2 satellites
Image collections are products that meet the minimum requirements to be used by applications. These collections are obtained from their official data providers and redistributed or distributed by the BDC project after processing. These data are also called ARD (Analysis Ready Data) products and are in comply with CEOS ARD specifications.
In the context of the BDC, image collections at the digital level (DN) and top of atmosphere reflectance (ToA) are used to generate collections at the surface reflectance (SR) level to be later used to produce data cubes.
The SR images are generated with software distributed by the agencies that provide the DN or ToA images, for example, for Landsat-8 images the LaSRC (Landsat Surface Reflectance Code) processor is used, Figure 2 illustrates the atmospheric correction processing in several products to generate surface reflectance products.
