Hi everyone. I have used SNAP to process a time series of Sentinel-1 SLC products to obtain the C2 matrix, saving them in GEOTIFF-BigTIFF format. Now, I am trying to calculate the Compact-pol Radar Vegetation Index (CpRVI) using the tool from SNAP. I can run it if I open the C2 matrix in SNAP, and apply the CpRVI directly. However, I am having problems when I try to run the CpRVI calculation through the Graph Builder, getting the following error:
Error: java.lang.String cannot be cast to java.lang.Number
I am using the 9.0.0 version of SNAP.
Thank you!
The error-message is interesting but the real issue is most probably that S-1 is not a compact-polarisation system and therefore this index cannot be computed. @jun_lu
Thank you for the quick response. It could be, but then, shouldn’t I get the same error when I run it directly in SNAP? If I open the C2 matrix in SNAP and run the Compact-pol Radar Vegetation Index tool, I don’t get any error, and it calculates it perfectly.
A JIRA ticket ([SNAP-3710] - JIRA) has been created to track the issue. We will look into the issue and thank you for pointing out the problem.
