The last plugin is named IdePix too. Should be S2 Toolbox OTB adapters.

  • S2 L1C/L2A reader: The reader is good, but there are too often issues with GDAL
  • S2 Resampling Processor: It is too slow.
  • C2RCC Processor: In general very good. Unfortunately, the quality of the results is not on the same level for the supported sensors. The automatic download of ancillary data is not working anymore. And the impact of the parameters is not well documented.
  • IdePix: Very good, but computing cloud shadow takes very long. Also classification of S2 takes too long.
  • S2 Toolbox OTB adapters: Never used them.

Some suggestions for SNAP:
1) Sentinel-2/3 data should be more convient if they are automatically open in image window (for example: in natural color ,in NIR-R-G combination by default),it will save great lot of time.
2) the FU classification for Sentinel-2 might be better if is is applicable to L2 data(currently it seems only available to L1C product)
3)mosaicking processor seems too slow for multiple neighbouring granules( in my routine work I have to mosaic 20 to 25 100km*100km granules, I ran SNAP mosaicking for several days yet can’t be finished, instead I ran under ENVI and it was finished within 1 hour).

My only feedback on the topics listed is the Sen2Cor Processors. I have found it simpler to do this step outside of SNAP. The tools are reasonably implementable and it’s easier to keep track of what’s up to date and see the processing info.

I think the Sen_ET plugin was great when it was working properly. It would be super if it is updated.
S2Resampling is too slow.
