About
Sentinel-2 Surface Reflectance (Sentinel-2) is part of the Piksel Surface Reflectance dataset series. The series includes an extensive archive of imagery acquired by the US Geological Survey (USGS) Landsat satellite programme and the European Space Agency (ESA) Sentinel-2 programme. The imagery has been validated, calibrated and adjusted for conditions in Indonesia, making it ready for straightforward analysis.
This product combines imagery from the Multispectral Instrument (MSI) sensors on Sentinel-2A, Sentinel-2B and Sentinel-2C. It has been processed to Level-2A, representing bottom-of-atmosphere surface reflectance, using ESA's Sen2Cor processor.
