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]

Yuxiao started the topic A major update on Sentinel TOPS module in the forum Sarproz Forum 7 years, 11 months ago
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] -

Yes, you are right, all the problems are solved now.
Thank you, Ivana

hi Ivana,
all these errors are relative to file permissions… -
ivca-cz replied to the topic sub-dataset function in the forum Sarproz Forum 7 years, 11 months ago
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

ivca-cz started the topic sub-dataset function in the forum Sarproz Forum 7 years, 11 months ago
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,

jaroslav replied to the topic Sentinel-1 oversampling in the forum Sarproz Forum 7 years, 12 months ago
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

Yuxiao replied to the topic Sentinel-1 oversampling in the forum Sarproz Forum 7 years, 12 months ago
Hi Jaroslav,
The oversample of Sentinel is currently not supported.
Is there a particular reason you want to oversample Sentinel data?

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,

Yuxiao replied to the topic S-1 coregistration error in the forum Sarproz Forum 7 years, 12 months ago
It is good to know this is a corrupted file instead of a sarproz bug. Can you probably try it again when you download again the correct file and see if it works well?

ok,
so, I have tried this – i used the same master and put only 4 wrong slaves in a “test” project.
Two of them were extracted (normally?):4 Slave images have not been extracted!!

Yuxiao replied to the topic S-1 coregistration error in the forum Sarproz Forum 7 years, 12 months ago
We need to investigate if with a good SLC file it ended up extracting a wrong area. That is why I need you to keep these files and do some tests to see if indeed there’s a bug in extracting slave images in such a case.
