I would like to ask about Graph Builder. I try to add file xml using sentinel-2a S2A_OPER_PRD_MSIL1C_PDMC_20151226T122831_R089_V20151226T030036_20151226T030036.xml in the read box. Is it possible to add the source because i look at the graph builder it use for ALOS,InSAR,and POLSAR? If possible could you tell me how to use and read the source. and second question how to use batch processing for sentinel-2 data. I try to add the same source it cant upload.
