OperatorException Error

Hi,
while doing a radiometric calibration on a S1A image, I receive an OperationException error type (an image is attached). The error says ‘Cannot Construct DataBuffer’. Could anyone please help me why and how to fix this error? Thanks so much in advance!

This could be the RAM , is not enough, similar problem is quite a lot discussed within this FORUM

Thanks! My system RAM is 8GB plus 16GB optane. Wouldn’t that suffice?

Thy should be enough, but what kind of S1A, do you use? And how do you calibrate it?

Take a look at this example of using gpt to calibrate to sigma0, but be careful this is “Sentinel1 SLC SM data”
