Hi @chrihartl, |
At least reading the SNOW_ICE MERIS L2 flag should work now. This should be checked by experts though. (I added TODOs in various places.) The main change was: - to rename MER_RR__2P_flags_data to MER_RR__2P_flags_IODD7_data - to derive a new version MER_RR__2P_flags_data from it: - Added SNOW_ICE - Replaced LARS_ON by DDV - Removed LOW_PRESSURE - Fixed typo in description of WHITE_SCATTERER (Presense -> Presence) - Fixed bug (?) in CASE2_S: Using bits 8+21 (was: 8 only, i.e. water bit 21 not set) The following references were used for this change: - http://www.brockmann-consult.de/beam-jira/browse/BEAM-1237?page=com.atlassian.jira.plugin.system.issuetabpanels:changehistory-tabpanel - https://github.com/bcdev/beam/blob/58f66c3d6697daab049abaa7284b26f652bfca5c/beam-envisat-reader/src/main/resources/org/esa/beam/resources/dddb/flags/MER_RR__2P_flags.dd - http://earth.eo.esa.int/pcs/envisat/meris/documentation/MERIS_IPF_evolution.pdf

The SNOW_ICE L2 flag introduced in MERIS IODD8 is currently unknown to the epr-api.
IODD7 is the latest supported, and apparently there is some backward compatibility built in for IODD6 and IODD5.
This fork proposes changes that introduce support for IODD8. In particular it is now possible to read the SNOW_ICE flag from a MERIS L2 product file ("MER_RR__2xyz.N1"). More details are in the commit message of the main commit:
Catalysts@9c7088c
Note that there are several comments having TODOs, mostly to indicate that the changes should be reviewed by experts and complemented if necessary.
Cheers
