 The Sentinel-2 data service platform provides users with the ability to process ESA's level 1c top-of-atmosphere reflectance data to generate atmospherically corrected bottom-of-atmosphere, BOA, reflectance, level 2a. Users can then access the process data through a user-friendly web page or by using a dedicated API. Additionally, the platform generates value-added products such as LEAF Area Index, LAI, and broadband hemispherical directional reflectance factor, HDRF. The platform has been tested at six different locations and the results have shown a high level of accuracy when compared to Landsat 8 data.
