    hi Ivana,
    you may want to try with the new version (just uploaded), it contains some changes in the sentinel code.
    if it does not solve the issue, we need to wait for yuxiao

    Hello,

    I am updating an old dataset using some more images, and for 2 of 3 datasets I get the error “index exceeds matrix dimension” in the “get contents” set. I know it helps to reprocess the whole directory again, but I don’t want to do it…

    Using version of 24-Aug.

    Thank you for your help, Ivana

  • Yes,

    you are right. I noticed this warning, expected that there is a problem with this image and it could not be extracted/coregistered. But I did not put it away, you are right. And after, I could not understand why “37 images could not be extracted” (and lots of extracted images could not be viewed, mostly from 2016) and why there are black…[Read more]

  • Dear Ivana,

    Among your warnings, there’s this one:

  • ok, once more with a different master

  • your log and lasterror.mat does not correspond with what you described here.

    please send them again.

  • Hello Yuxiao,

    I have encountered a strange behaviour in the coregistration step of S1 data (see the screenshot and log attached). When I click to see the extracted/coregistered images, the number of coregistered images is higher than the number of the extracted ones. In fact, the last two coregistered images have a large black area (missing…[Read more]

  • Hi all,

    Today we’ll release a major update on Sentinel TOPS module. This update will include two main functions:

    1. Support of Sentinel-1B data;

    2. Support of automatically merging adjacent images (on azimuth direction).
    Now, if you have two (it can be more, as long as all of them are adjacent) TOPS SLC images, on the same date, same orbit,…[Read more]

  • periz replied to the topic sub-dataset function in the forum Sarproz Forum 8 years, 1 month ago

    hi Ivana,
    all these errors are relative to file permissions…

  • Hello,

    I am attaching another error I got within the coregistration process, it looks similarly, so maybe it is a kind of general error… I don’t know.

    Please let me know if the problem is on my side… but I am encountering it for the first time in two different (coregistration) directories.

    Thank you, Ivana

  • Hello,

    I am using the sub-dataset function for the first time and I found a small bug (however, it does not let me continue). Attaching the log. Despite all the warnings, the refl map looks normally, the “final” problem is with writing the GCP data.

    (linux-compiled version)

    Thank you in advance,
    Ivana

  • Hi Yuxiao,
    I just got an advice, that oversampling could improve the results, and could not though, so I wanted to try it.
    Since it’s neither likely to help, nor supported in SARPROZ, I don’t see a reason to raise a dust.

    Jaroslav

  • Hi Jaroslav,

    The oversample of Sentinel is currently not supported.

    Is there a particular reason you want to oversample Sentinel data?

    yuxiao

  • Hello,
    I wanted to oversample my Sentinel-1 data, but got message, that oversampling for Sentinel-1 is not supported.
    Is it not implemented yet or just a tomporary problem?

    Regards,
    Jaroslav
