The number of NoData pixel in the output L2 composite product is too high #57

Open JRGZ opened 4 years ago

Dear Oliver,

I'm using MAJA to create a L2 time series for Ireland and I'm running into an issue in one of the tiles (29UNV). I'm producing a complete time series from 2015 to 2017, and for all other tiles the process works fine. For 2016, however for 29UNV all images after 2016-03-17 will execute fully (including writing the L2 products to the output folder) but then the algorith will rename the folder to a L2NOTV*. The only error message I can find in the log file is "The number of NoData pixel in the output L2 composite product is too high." It will do this for all images in the tile for 2016, then in 2017 it works fine again. I have attached the log file for S2A_MSIL1C_20160330T115422_N0201_R023_T29UNV_20160330T115425. All L1 products going into the process were obtained using the PEPS downloader.

Any help would be much appreciated.

Kind regards, Jesko

I solved the issue. The problem was in the 2016 CAMS files. It turned out that none of the tiles produced any usable results (all bands where black). After deleting the CAMS files, the L2 products came out alright.
