SARPROZ ©

Hi Yuxiao,

thank you, it is ok now. And the December 2015 interferograms are the most coherent ones (for my AOI)!

Unfortunately, I can still see few phase ramps within the interferograms (about 3 in 30-40 interferograms). It seems that this did not improve since October. Do you need the test data?

Thank you again, Ivana

Hi,
Thank you for supporting. Its OK. it seems co-registration of sentinel images is OK.

SLC extraction is now correct

Thanks

The new version is available for download through the “manage version” module (pcodes and compiled for win and lnx).
please try it out and let us know!

Hi all,

The bug that impacts most S1A images acquired after November 2015 has been fixed and I have submitted the code to Dan. The next new version of SARPROZ that should come out in the next days should just work fine.

Please let me know if the new codes work well or not,

Thanks to you all!

Yours,
Yuxiao

hi qingli, please zip all files together

HI Qingli,

Sorry that I haven’t log on to QQ for a while.

I didn’t see anything specific from the log, so I will need to download your data and test it out. I will let you know once I’ve got the result.

Yuxiao

Dear Yuxiao,
i have already send the log file to u via QQ.
However, i noticed you didnot receive it.
Now, please see it in the attachment.
i already checked the amplitude of each image and they are correct without any dark areas except for the lake.
Thanks,
Regards,
Qingli

Hi Dora,

if your problem persist, we need to find a way to get your data and tested out.

Do you have a ftp or something like that so we can get the scene of data that is wrong? Or we can teamviewer together to take a look.

Yuxiao

Hi Daniele,

I checked the files and I didn’t find any problems. I copied the data using an usb disk.

Hi all,

I have been reported the inconsistency between images acquired after November 2015 and before that from a number of people. I am currently investigating this issue and I will come back to you once I get a conclusion.

Thanks to all,

Yuxiao

Dear all,
As I wrote in my previous mail, I received the same problem in co-registration of sentinel images in 2016 and some month at the end of 2015. it seems, there is some discrepancy between this image and previous image in their orbits and also these new images seem darker than previous image. then coregistration fails for theses images.
thanks

Hi Dear Matus,

I didn’t see anything particular wrong about the software. It looks like the thing is coming from data.

One thing you can do is to check if there’s some heavy raining on either of the dates.

Meanwhile I will take some time to download and take a look at your data also.

Yuxiao

I do not know what you mean with “grayed out”.
I’d suggest to show you a comparison between a normal image and what you call a “grayed out” one.
Isn’t it that it was raining? Anyway, if problems, I guess they belong to the data, not to the extraction code…
About the examples you attached, the first 2 images look coregistrable but shifted.

Dora,
check the formatting of text files (end lines/carriage returns/tabs/…)
it may have been messed up by some operations (like ftp-ing files from linux to windows)

Hi Yuxiao,

since I am working in windows and the untar option doesn’t work, I previously unzipped the images in Linux. Is this the cause of the problem?

Thanks,
Dora

Hi Dora,

I’ve downloaded your data and replicate the steps. However I didn’t seems to find anything wrong there. I successfully extracted the image. A screenshot of my process is available here.

Can you give us more infos on your case if it keeps going…[Read more]

Hi Dora,
together with Yuxiao we are downloading your data and checking what’s the problem.
We’ll let you know soon
