Worldview 2 Product reader

I can’t open the .xml file for worldview 2 product. When using the file type for worldview 2 products the files won’t appear in the folder location.

You should choose the _README.XML file within the product, in order to open it in SNAP:

Best regards,

Hi, Oana!
I’m having troubles with opening WorldView 2 product in SNAP 9.0. I’m getting the following error:

at org.esa.s2tbx.dataio.worldview2.metadata.TileComponent.getScalingFactor(
at org.esa.s2tbx.dataio.worldview2.WorldView2ProductReader.readProductNodesImpl(
at org.esa.snap.core.dataio.AbstractProductReader.readProductNodes(
at org.esa.snap.core.dataio.ProductIO.readProduct(
at org.openide.util.RequestProcessor$
at org.netbeans.modules.openide.util.GlobalLookup.execute(
at org.openide.util.lookup.Lookups.executeWith(
[catch] at org.openide.util.RequestProcessor$

Seems like SNAP cannot load the ABSCALFACTOR parameter from image’s XML file, while this parameter is present there (example):


Do you have any ideas about that?


I just tested with the WW2 products that I have and no error occured (but the names of the bands within the products I have are different…). Can you send me the product somehow? Or indicate from where I can download it? Or try to show its structure?

Here is what I have and you can also see the bands name

Oana, thank You so much for your reply!
Please find the filestructure attached in fileList.txt
and all the files except tiffs in
If You gave me your email or other contact, I would give You the link to the full data. (424.8 KB)

I sent you a private message yesterday with my email address.
From our quick tests and analysis, we noticed that in your product metadata the version is 29:
isd/IMD/VERSION 29.0
while in our products metadata the version is 28.
The WV2 reader from SNAP expects a bandid “MS1”, while in your product I see “Multi”.
[isd/IMD/BANDID Multi - in your product, while isd/IMD/BANDID MS1 - in our products]
[isd/RPB/BANDID Multi - in your product, while isd/RPB/BANDID MS1 - in our products]

A first conclusion is that the reader from SNAP should be updated in order to take into account this type of bandid too.
I will get back to you after testing with the actual product. (many thanks for providing it to us)

After testing with your product, I confirm that the reader must be upgraded.
I created a ticket in our issue tracker SIITBX-492
After some quick code changes that we made, we managed to open your product:

These changes will be available in the next minor version updates of SNAP 9 (no fixed date yet, I will keep you posted)
