## Inputs, algorithm and outputs
The processing chain creates a synthesis image of multiple Level-2A tiles produced with [MAJA](http://www.cesbio.ups-tlse.fr/multitemp/?p=6203). A database of over 150.000 freely distributed products is available under:
The processing chain creates a synthesis image from multiple Level-2A tiles produced with [MAJA](http://www.cesbio.ups-tlse.fr/multitemp/?p=6203). MAJA Level 2A products can be obtained:
The algorithm to combine the inputs into one single synthesis is described [here](http://www.cesbio.ups-tlse.fr/multitemp/?p=13976).
*[From Theia, the French Land data centre, for several countries or regions](https://theia.cnes.fr/atdistrib/rocket/#/search?page=1&collection=SENTINEL2&processingLevel=LEVEL2A)
*[From PEPS, as an on-demand processing, anywhere on the world](https://github.com/olivierhagolle/maja_peps)
*[Using MAJA on user side](https://github.com/olivierhagolle/Start_maja)
*[within the Sen2Agri project](http://www.esa-sen2agri.org/)
The weigted average synthesis method to combine the inputs into one single synthesis is described [here](http://www.cesbio.ups-tlse.fr/multitemp/?p=13976).
Once synthesized, a Level-3 product is generated further described in the [format description](http://www.cesbio.ups-tlse.fr/multitemp/?page_id=14019).
A collection of Level-3 products can be found under:
Theia also produces [**Level 3A products with WASP over France**](https://theia.cnes.fr/atdistrib/rocket/#/search?page=1&collection=SENTINEL2&processingLevel=LEVEL3A), and soon over all the zones already processed by Theia.
