Perhaps you can read the messages given by the software: why it is not working?

hi Sandersax,
if you want to apply spatial phase unwrapping, please download the last sw version, a bug was found and fixed.

hi Sandersax,
to work on a single interferogram, use this module: http://sarproz.com/manual/insar_analysis_site.html
to see a description of insar parameters, check this http://sarproz.com/manual/insar_params.html
The idea is that, to convert the phase into mm, you have to unwrap the interferogram
so, if you check the “unwrap” option, then you can…[Read more]

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

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]

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]

Hi Matus,

try the new pcodes
d

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 Ivana,
we are adding an option for visualizing which image has the problem.
I’ll send you the pcodes by email, there are also some other changes going on, keep it as a temporary version.
You’ll have to use the “debug” option in advanced parameters.
In that way, you can post here which is the image with problems, Yuxiao needs to look into it.
bye

Hi Santiago,
send us the file name of a VV/VH image so that we can download and check it

Hi Sg,
– here http://sarproz.com/manual/slc_data_module.html you can read that you can update your dataset, trying to coregister again the failed images (be careful, when you press buttons always read carefully the messages given by the sw. in particular, if you do not check the “update” option you may overwrite your work if you press randomly…[Read more]

hi Nader,

as mentioned by Yuxiao in a previous topic, there could be several reasons for having a ramp on an interferogram.
E.g. orbital inaccuracies, coregistration problems, atmospheric artifacts and so on.
Yuxiao is checking it because the Sentinel processing still deserves some extra care.
Generally speaking, forgetting for a moment that you…[Read more]

Hi Nader,
in your picture you can see 2 different types of NaNs (not-a-number):
a. some spots here and there (usually in areas of steep slopes): they correspond to SRTM missing data. Sarproz interpolates those values when the DEM in SAR coordinates is generated. You can check the result after your process it, by plotting it with the “view…[Read more]

The new version is available for download through the “manage version” module (pcodes and compiled for win and lnx).
please try it out and let us know!

hi qingli, please zip all files together
