MAJA (MACCS ATCOR Joint Algorthm) is a level 2A processing chain that:
Historically the MACCS (Multi-sensor Atmospheric Correction and Cloud Screening) chain was developed jointly by CESBIO and CNES for Venus mission and extend progressively to other missions (SPOT-5, Formosat-2, Landsat 5, 7, 8 and Sentinel-2A/B). CESBIO design the algorithms and develop a prototype, while CNES took in charge the operational version of the chain, which CESBIO largely contributed to validate. More recently, CNES+CESBIO and DLR decided to pool their efforts to develop the MAJA chain (MACCS-ATCOR Joint Algorithm). This chain is an evolution of the MACCS chain in which methods from the DLR’s ATCOR chain will be progressively added. In order to celebrate this agreement, MACCS 6.0 version has been renamed to MAJA V1.0.
MAJA 4.X will be relased in open source in 2020 with a new architecture which allow better integration with OTB and possibility to CESBIO and other researchers to reuse and update algorithms.
MAJA is now used on multiple programs, including Venus, Sentinel2, Landsat, Formosat-2, SPOT5.
CS promotes the MAJA chain as a product (cf. MAJA)
