Hi Matus,
try first the code I passed you by email, we’ll upload it after a few more tests
thanks

Hi Mahtab,
write an email to me, I will pass you a piece of code which may solve this issue, we need some tests before uploading the complete new version.
thanks

If you check your failing SRTM file,
it should be very small, you can open it with a text editor, you will see it is actually an html file, not a zip one
delete it and all similar files, that will solve the problem (the software will download them automatically when needed)
if you are not sure about which file is good, which one is not, delete all…[Read more]

Hi Jaroslav,
first of all, take this as a temporary message. We are working at general solutions for avoiding these problems.
Secondly, when you get such messages, the first thing you should do is checking if this has an impact on the phase.
The quickest solution is temporarily discarding images that generate this problem.
Otherwise, the problem…[Read more]

Please update your code with the lastest version via the “manage version” module, that you find in the “dataset selection” window. this is a bug that we already fixed.

Hi Prashant,
Yuxiao has been working at the weather data module for the past 2 weeks, rewriting the code and making it stable against changes on the online weather database (the error is caused by some data returned in an unusual format). We will release a new version very soon. Please be patient a bit more.

Hi Prashant,
such an error -as you point out- is affecting a Java command. After a quick search online I found the following:

“Probably for some reason the connection dropped. There are a number of different reasons that can happen, including

system overheating
driver problems with your ethernet card
hardware problems with your…[Read more]

Hi Jaroslav,
I assume you are talking about azimuth shifts. That is common for Sentinel and it’s not a problem.
You should not have any coregistration issues.
Moreover, you can put consecutive images in the SLC folder: Yuxiao developed a simple algorithm to merge them, and you can treat them as a whole image.

There are many things you don’t say,
as how you calculated those parameters, what does your dataset look like (in terms of number of images, distribution of acquisition dates/baselines/doppler). then we should check the original parameters as reflectivity, ampl stab ind, spat coher and so on.
anyway, as a general answer, if the spatial coherence…[Read more]

Hi Mahtab,
the life time is calculated from amplitude time series of good scatterers using this module http://sarproz.com/manual/amp_series_proc.html. The analysis is carried out on the amplitude series of single pixels.
The easiest way is to use the on-off model, then Tin and Tfin (birth and death dates) of targets will be estimated, their…[Read more]

Hi Prashant,
we are working on it.
We’ll send an update soon

Hi Artem,
we are investigating it.
However, it looks like this is not going to generate errors. So, for the moment you can ignore it.

Hi Jaroslav
sometime in December the SRTM ftp download changed the format and we uploaded the new code on Dec 12.
You have to update your software version. If you cannot use the “manage version” module, write an email to me, and I’ll send you a link

I confirm that the weather data download works.
If it does not on your side, unless you present an error, I am forced to think that it is a network problem between you and the weather database.
About the message you get at the beginning, it is due to a recent licensing issue. It is a temporary problem, do not pay attention to that message.
bye

Hi Kapil,
you have to patiently read the messages from the software
if you read your log files, it’s full of WARNINGS. you have to check them
your data looks corrupted because some infos are missing. please check it according to what the software says

this is just an example:
Your S1A imgfile:…[Read more]

please attach the log file after zipping it

Hi Kapil,
if you want to get assistance you must zip log and lasterror files and upload them here. Without those infos we cannot be of any help.
About the weather data download, it looks like a network problem on your side.
But again, we need log and lasterror.mat files (and you have to zip them before uploading)

fix for the linux compiled version: https://we.tl/yC88CE1xgB
