Hi Matus,

as we have checked together, the sw was not finding the DEM that was loaded.
Don’t forget to read the messages, which tell you if something wrong is going on…

the error seems being generated by a corrupted site description file
if you delete the SiteDescription.txt file, it should work
anyway, a pcodes bug fix is being uploaded

The idea was correct,
but you should not LOAD the points, you should pick up the file you saved using the menu on the left (menu item: choose a real file).
Save/Load options use an internal format. While saving a subselection of points from scatter plots writes values in a SxL matrix (the common sw format). Make sure to choose also a parameter for…[Read more]

symmetric ranges are needed only in the APS processing, here you are not specifying in which module you are working.
it sounds strange saying that most points are stable and only a few move a lot
in any case, whether searching for a wide range of values can affect the estimate depends on many factors, like number of images and their time…[Read more]

DSF is the downsampling factor of the final APS. R is the length of the correlation filter (pixels).

together with the log file you have to include also the lasterror.mat

– you have to zip log files
– check this http://www.sarproz.com/groups/sarproz-group/forum/topic/sarproz-release-2016-00/

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
