Minimize Level-2A

The Level-2A product provides Bottom Of Atmosphere (BOA) reflectance images derived from the associated Level-1C products. Each Level-2A product is composed of 100x100 km2 tiles in cartographic geometry (UTM/WGS84 projection).

Level-2A products are systematically generated at the ground segment over Europe since March 2018, and the production was extended to global in December 2018. Level-2A generation can also be performed by the user through the Sentinel-2 Toolbox using as input the associated Level-1C product (demonstrated below).
