Dan,

I’ve checked it with the DEM Visualization tool (screenshot attached), finding no NaNs, but according to the manual this displays the DEM in Geo coordinates, which file corresponds to the DEM in SAR coordinates?

Santiago,
you need to plot and check the DEM in SAR coordinates

I enclose my log file,

I remember that when you warned me about NaN values in my DEMI checked it and I converted them to zero.
When I made that correction I restarted the process again from the external DEM selection to make sure it was updated.

If it takes too long,
as I previously explained, it means that there is something wrong.
You did not include the log file, it seems the error is happening in a file that has been modified in the last version.
Anyway, by remotely sensing you case, I think your DEM is containing NaNs.
If you remember, I told you to check it, since your DEM is not…[Read more]

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,

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.

Yuxiao

Dear Yuxiao,

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