Hi,

I am using l2bin to create daily l3b files, which is then followed by l3mapgen.

My issue is with L2 flags and their implementation at the l2bin stage. Is there a way to output masks as bands in the L3b file rather than masking directly at the l2bin stage?

I would like to have some flexibility with flag use and would prefer to apply masks later on in my processing stream.

Thanks,

Dan

Level-2 flags (masks) cannot be output products of the l2bin. The reasoning is that for a given binned output file pixel, you can have multiple source input files which contribute to the bin aggregate depending on the flag (mask) of the particular source input file. Once a file is binned, the connection between the source flags and their respective source pixels is lost, so flagging after binning would not be useful.

Compared to l2gen, binning is not time- or space-consuming, so running l2bin with different flag settings may not be a big problem.
