java.lang.NullPointerException when importing ALOS-2 L1.1 data

Hello everyone,

I encountered the following error when importing ALOS-2 L1.1 data:

Any ideas what might be the cause?
I am using SNAP Desktop Version 7.0.4 in HPC environment.

This is my first time dealing with ALOS data.
Any helps will be appreciated!
Thank you in advance~

I’m not sure if SNAP supports these products. Mabye someone in here has tested it so far.
Did you get them from JAXA?

Hi @ABraun,
Yes, I got the data from JAXA.

A stupid question: So what kind of product does SNAP support?
Thanks :smiley:

I think I have also ordered ALOS-2 ScanSAR data one day, but I am not sure if I was able to load it.

Let’s ask one of the developers: @lveci can SNAP read ALOS-2 ScanSAR L1.1 products?

From the Product Format Description (PALSAR-2_xx_Format_CEOS_E_f.pdf), WBD stands for “Scan SAR nominal [14MHz] mode Dual polarization”.
Based on this, I suppose my data are not WideBeam products, no?
Because I also see the following info:
VBS: Scan SAR wide mode Single polarization
VBD: Scan SAR wide mode Dual polarization
Thanks :smiley:

good point, thank you. I changed the question.

Thank you as well :smiley:

Hello developers @lveci and @mengdahl,

Any ideas regarding this error?
Or ALOS-2 ScanSAR L1.1 products are not supported yet in SNAP?

Thank you in advance!
