I don’t see easily a reason for that residual ramp. This would deserve some deeper investigation. The results anyway are now much better.
About the geocoded reflectivity map: are you keeping a 1×1 downsampling? Otherwise, u’ll degrade the resolution. The mean kml generated from the GCP module is downsampled 8×8. That map is generated just to give…[Read more]

Hi,
I’ll be grateful if you sent me new pcodes, since i’am unable to
update using the manage version module.
Thank you in advance,

Hi Periz,
Thank you very much for your response. I do think it is related to a faulty memory as I recently added an 8 GB RAM which could have caused this issue.
Anyways, The problem does not happen that often recently, but if it persists I will definitely try what you suggested.

Thank you very much for your help. I really appreciate it!

I also have two more questions:

1- Although the results obtained after residual orbit removal were better, there are still interferograms that are affected by ramps (see attachment). Could this still have influence on my results?

2- The other issue is with the GCP selection. I identified a lamp post as a GCP and when opening mean KML, everything…[Read more]

Hi Periz

Thank you very much for your response.I checked the interferograms and they had ramps. I obtained better results (please find attachments) when I used the function you mentioned the the parameters you specified.

Is there a way to know how good these results are?

Many thanks

hi qingli please zip and attach mat and log files

@ Yuxiao, thaks so much, problem resolved

This error is solved and a warning is added when the wrong S1 SLC folder is placed.

Benattou,

1. please be cautious when you extract S1 SLC files with third party unzipping softwares;
2. The Correct folder name for SLC should be in “S1*****.SAFE” format;
3. I added a warning when your zipping software do not produce this correct format (in your case, there were a S1A***.SAFE format under one S1***** folder. I don’t even know how…[Read more]

Did you use the patch I posted?

Another way to get it work is: go to Select Dataset -> Advanced Parameters -> tick “Debug Messages”.

Then please repeat the steps and pass me the log file.

The idea is that we need some more information on this bug.

let me know,

Q

dear Yuxiao,
sorry i have the same error, there’s no warning.
maybe there’s something in the data changed because i used to process sentinel data before and didn’t have a problem in the data reading.

Hello Benattou,

Sorry for this, but you’re not attaching the one I want.

If you used the patch, and everything went “right”, you should be able to see the following warning:

combine_3_subswath(): Error Combining meta files of subswaths! Debug file is saved in S1-meta-1234-56-78.mat!

Then that mat file is the one I need.

I am think of…[Read more]
