    thank you for this, i'm doing my master thesis on SAR and InSAR and this was pretty helpful :D

    Hi! I'm doing a MSc thesis in which I'm going to work with a SAR dataset, from Sentinel-1. These videos have been suggested to me and they have been fantastic!
    A question @ 21:00, I'm confused regarding the workflow. Do I do "regular" SAR pre-processing first and then do the PolSARPro processing? Thank you!

    Hi, could anyone confirm if the explantion in 37:40 is correct?

      Yeah, it didn't make sense to me either.. She said that the returned VH signal would be relatively higher for volume scattering makes sense, but it is not what is shown in the chart. I assume there was a mistake in the chart, but it seems bizarre that that would happen.

    Great intro video, really helped me with SAR classification!

    Thank you for your presentation! By the way, I'm not good at English... If you don't mind, could you make a English subtitle for that presentation? Session 1 has a script but 2,3 and 4 haven't.. It's really good educational presentation!

    Great video with invaluable information regarding Polarimetric analysis! well done!
    I have a question though. My config.txt is at first created in T3 directory and I copy paste it in decomposition directory, otherwise I have this error:
    A processing error occured !
    Could not open configuration file : decomposition\config.txt
    When I copy the config.txt in decomposition I have this error:
    Segmentation fault.
    What am I doing wrong?
    Thanks in advance!

      Did you manage to solve the issue?

    So if you're sewing a plot, avoid geometric shapes like polygones when you plant the seeds
    If you're building home, avoid 90 degrees angle, make it look like a borrow
    If you're kids play outside, make sure they don't leave the forest.
    Got it!

    Why does the runway has high Entropy values???

      Although it's a surface, it is rough, so scatters in different directions. That would be my guess.

    PolsarPro is not available... Does Snap can do the same?

      Yes you can perform this processing with SNAP
