I need to work with Sentinel-2 data, and I have been having difficult with the ESA toolbox (SNAP), so I've decided to process the imagery with QGIS instead.

My question is, is there a significant difference in the quality of atmospherical correction results that would justify working with SNAP instead of QGIS?

  • .SAFE format is to organize the information. I don't understand what you want... If is correct atmospherically the scenes, .jp2 will be useless for Sen2cor outside SNAP – aldo_tapia Dec 1 '17 at 15:58
  • I want to correct the scenes outside of SNAP (so, that is, not on Sen2Cor). But I just realized I made a mistake and thought .SAFE was also a specific image format. My bad, I will change edit the question again. – Fer Dec 1 '17 at 16:45
  • Also, you are wrong about Sen2Cor... Read carefully step.esa.int/main/third-party-plugins-2/sen2cor – aldo_tapia Dec 1 '17 at 17:27
  • I am sorry, but I do not understand your comment. I am wrong about what regarding Sen2Cor? – Fer Dec 1 '17 at 17:35
  • Sen2cor is an add-in to SNAP... I've never use it inside SNAP, always from cmd/terminal. Try from command line. SNAP take account water vapor, cirrus, aerosols and others variables (such land use - computed from sen2cor-, snow, water bodies, DEM)... So the performance of this tool is better than QGIS DOS or i.atcorr – aldo_tapia Dec 1 '17 at 17:39
