hello,yuxiao, here is still the problem of loading TOPS data .
i attached the log. and last error. mat file and please have a look with them.
Thanks,

here is the reminder in the matlab.

Hi Daniele,

thank you for your quick reply.

I’ve got reasonably good results using the Star images graph.
By the way, I would like to check phase unwrapping files and where I can find them?
Do I need to use small area processing module for that purpose?

thanks,
Venera

that’s exactly the purpose of using a GCP. Anyway in Sarproz you can correct such shifts also later with the geographic corrections module

I encounter an error when i choose “Manage version” and click “Go”. This following error occurs:

Connecting to the Server…
Fatal: Host key did not appear in manually configured list
failure in calling psftp
Aborting…
sftp_multi_platf: job “get” failed!

What is wrong with your manage version module?

Hi Periz,

I viewed the reflectivity map with 1×1 downsampling from (Extended geocoding). There appears to be a slight shift (several metres) between the reflectivity map and the actual structures from Google Earth. Do you think this can/should be improved by choosing better GCP?

Thank you very much!

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,

i already zip these two files. please have a look.

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!

Moath

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

Moath

Hello,

That was a very stupid mistake of mine and it is fixed.
