I’d just like to check something about the way the GPT tool does its processing. I have a S1 pipeline that takes quite a long time, in the end generating a ~1.3Gb geotiff. If I watch the output directory while it runs I see the file created slowly increase in size. How does SNAP handle the data? Does it work line by line or pixel by pixel? Does it process the entire image at the same time?
I have an xml chain of commands, and I am trying to figure out if it finishes one step of the chain completely before moving on to the next step, or if it finishes part of the image and then pipes it to the next step.
Thanks for your help!
