WebbThe Landsat 8 OLI sensor is more sensitive so these data are rescaled into 16-bit DNs with a range from 0 and 65536. Also these data have been converted to reflectance, rather than radiance, so DNs can be manually converted to Reflectance in a single step. Webb27 nov. 2024 · Landsat 8 Surface Reflectance data are generated from the Land Surface Reflectance Code (LaSRC). LaSRC makes use of the coastal aerosol band to perform aerosol inversion tests, uses auxiliary climate data from MODIS and uses a unique radiative transfer model. out and about products
