asterios_papas · November 27, 2015, 2:24pm

Dear all,
Is anybody else experiencing problems with sentinel 2 product opening in the latest snap 2 software?

Thank you

Hi,

Which particular product are you trying to open ?
Do you experience problems with all products ?

Thanks

asterios_papas · November 27, 2015, 4:28pm

with all sentinel 2 products downloaded fromm the esa hub. i’ve tried to open it either from the open product selection, or from the import sentinel 2 selection.both seem not to work.

jmalik · November 27, 2015, 4:38pm

Please mention the exact product ids.
I just tested S2A_OPER_PRD_MSIL1C_PDMC_20150714T123646_R019_V20150704T102427_20150704T102427 and it works for me.

Also mention your OS.

There is a on the bottom right corner. Could you click on it, the click on “show and report problem”, the “details” and send us the error message? Thanks in advance.

Thank you @asterios_papas for reporting

@Nicolas this is :

                                               this.getProductResolution().resolution,

                                               0.0, 0.0));
} catch (FactoryException e) {
    throw new IOException(e);
} catch (TransformException e) {
    throw new IOException(e);
}


product.setPreferredTileSize(S2Config.DEFAULT_JAI_TILE_SIZE, S2Config.DEFAULT_JAI_TILE_SIZE);
product.setNumResolutionsMax(getConfig().getTileLayout(S2SpatialResolution.R10M.resolution).numResolutions);
product.setAutoGrouping("sun:view:quality");


List<BandInfo> bandInfoList = new ArrayList<>();


List<S2Metadata.Tile> tileList = metadataHeader.getTileList();
if (isAGranule) {
    tileList = tileList.stream().filter(p -> p.getId().equalsIgnoreCase(aFilter)).collect(Collectors.toList());
}


// Verify access to granule image files, and store absolute location

This suggests we still have an issue with the openjpeg executables (opj_dump here probably did not execute properly)…

after evaluation i understood that this problem is only on my computer. my important question is, is there any way to fix this?
i tried to uninstall and install it again and it didnt work, either deleting every directory.
Is there anything i can do?

thivanlekhoa · February 2, 2016, 4:59pm

I have the same problem with my computer!

gorang · February 9, 2016, 7:12pm

Dear Helpers,

I do not manage to open S2 product (MSIL1C in jp2 format).
My version of SNAP is 2.0.2 and I am using Window 7.

After creating manually the folder .snap\var\cache, I just have the message ‘Error while reading file’.

I manage to open this same file with QGIS.

Is this problem known for next version of SNAP ?

BTW, I manage to open S1 product without pb.

Thank you.

abgbaumann · February 29, 2016, 10:54am

Hi Celine,

I tested it and I can not open them either. But why do you only want to open one band&tile? Just for visualisation? If so I would recommend IrfanView. You would need to install the software itself and the plugins (to be able to open jp2).

Cheers
Andreas

Celine · February 29, 2016, 2:11pm

Hi Andreas,

Thanks for the IrfanView advice, QGIS is pretty good too.
As I am not sure to have well understood, could you precise if there is a solution if you open all the bands&tiles?

Thanks,

Céline

abgbaumann · February 29, 2016, 2:19pm

Hi Céline

To open a S2-dataset you have to open the XML-File in the main directory:

I hope the graph above is not too obscure.

Cheers,
Andreas

Celine · February 29, 2016, 2:31pm

It is very clear. Thank you very much.
I can open the S2-dataset now (although it is a bit long to read all the bands&tiles).

Cheers,

Céline
