I recently upgraded to SNAP 11, and I’m having troubles with procedures using gpt that worked fine with SNAP 10. They are processes that start from L2 files in NetCDF format generated using SeaDAS (binary l2gen).
Interactively, the files load correctly in the SNAP graphical interface and, for example, they are exported correctly to BEAM-DIMAP. I’ve generated a simple xml that only reads the L2 and writes it in BEAM-DIMAP format. With SNAP 10 it works correctly, however with SNAP 11 the reading process with the gpt Read command returns the following error:
