Hi all,

Good day. I am trying to use ISCE2 to StaMPS for PSI processing. I got this error when I tried to run the stamps(2,2).

The error indicates that line 49 is the problem. So, I studied and found out that my Ko is a negative value, which is causing this problem. Further investigation into the Ko value, I understand that it is from my inc angle (that I loaded from ISCE2), which contains negative values (which is wrong, I guess?).

The -ve value brings a problem to my line 49. Did anyone have experience or any idea on this? 

I appreciate your help and response. Thank you in advance.

Regards,
Ai Ling

Hi,
I resolved this issue by redownloading the latest version of gdal2isce_xml.py.
Thank you.

Regards,
Ai Ling
