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,

Dear Dan or yuxiao,
Here is a new problem.

When i try to do slave extraction, there is a error.
Please find the master slection area, the footprint.kml, lasterror.mat and log file in the attachment.
Could u help me to check why it cannot work?
Thanks,

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.

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,

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.

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,

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.

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,
I’ve found some strange error while working with SLC IW images from Sentinel-1 usually starting from November, 2015. Images from >Nov,2015 in more than one track have grayed out intensity and corregistration fails everytime I am using them.
Few examples are:
SLC IW from ASCENDING track with relativeorbitnumber:102 over the area centered…[Read more] -

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,

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.

Nader,
as a kind of general comment, with 6 images you should use a multi-master approach, and use also unwrapped interferograms. However, there are many comments more for your case, and also many options that could be chosen to help you solving your case. So, again, I suggest you to take a direct contact with some of us and have a remote session…[Read more]
