Hi dan,

Then it is desirable to ckeck it even if estimating displacement only (from what you say I interpret that it is used to remove the topographic phase reding it from my DEM, which in this case is a high-resolution one).

I have tried to re-process my dataset again with this option checked, and apart from taking too long (~8 hrs) I can’t…[Read more]

Checking External DEM means removing a phase component proportional to what is written in the external DEM file.
So, this is not directly related to movement.
However, you estimate the movement from phase time series. If you remove or not remove a component from the phase values, clearly you are changing your data. As a consequence, the estimated…[Read more]

Hi Nader,

yes, there are some residual fringes, when Yuxiao will have time he will improve his code.
In the meanwhile, as previously said, you can still process your data. There are several ways to remove or at least reduce spurious fringes.
The first thing to do is using the residual fringes estimation and removal module: did you do it?…[Read more]

Dear all,
Who can lead me in next step. As I sent the fringes, there is good fringe in this step (with some ramp), but I don’t know why I can receive good results as displacement?

Best regards
Nader

Hi Matus,

try the new pcodes

thank you,
please see attachment

upload exceeds allowed size

your interferograms. screenshot them.

Dear Yuxiao,
Please inform me on the files that I must send. (the files and their formats)

Hi Nader,

Dr. Perissin has already introduced you two methods in the post above. If you can also post your interferograms with fringes on to the forum we can help you by taking a look and giving suggestions.

Dear Yuxiao,

For testing my results: what method can you introduce? how you can help me in this check?
Nader

if you pick up manually a GCP,
you should not get significant problems

however, just make sure not to have NaNs in the DEM in SAR coordinates
in case, place them to zero

Hi Yuxiao,

can you please send me the compiled version for windows 64 bits with it?

Thank you for your help,
Dora

Hi Daniele and Yuxiao,

thank you, the problem was solved by deleting the one image,

it is S1A_IW_SLC__1SDV_20151004T045254_20151004T045321_007998_00B312_5C90.SAFE (IW3),

however now, the process of slaves extraction gets stuck on a different image,

S1A_IW_SLC__1SDV_20151109T045242_20151109T045309_008523_00C10E_3329.SAFE
(with no…[Read more]

Hi Dear Dora,

The warning inside your logs is fixed and your master image should extract just fine. I’ve already tested out the sample data you’ve uploaded and the extraction works well.

To eliminate the warnings you can just download the file I’ve uploaded, extract them and overwrite with the exist ones in your pcodes folder.
