Hi Dimitris,
1. please take the time to read the messages from the software. You can learn a lot from them. They are included in the log file you attached.
2. one of the messages says: “If you need assistance, please include the file lasterror.mat “. without that file we cannot help.
3. here you have some material to learn how to use the software…[Read more]

Hi Daniele,

I did exactly has you showed me yesterday and I don’t see any problem about the xml files (please find the capture in attachments) or any files. I corrected all of those which were empty. They work fine on SNAP.
So I don’t understand what problem might be. Only works if I import only one S1 dataset.

Hi Joana,
such message is a warning, not an error. The log also says that the file you cannot modify is a file contained in the original SLC data, and this is not a problem, since the software is not going to overwrite those files.
Your problem is that your SLC data are partial or corrupted. The log says:
Error in s1_slc2file(): can not find…[Read more]

Just to note here that this issue has been solved.

For other’s reference, when one is importing SLC data:
1. Check if the input latitude/longitude is consistent with the MasterArea.kml (that is generated by clicking “View”);
2. Check if the extracted Master image is corresponding to the MasterArea.kml (you can see the master image by “View…[Read more]

Hello Alicia,

I suggest we set up a remote session for me to take a look at your dataset. Are you familiar with using teamviewer?

In this way, we could quickly go over your dataset and diagnose the problem.

If you have teamviewer installed, then email me at qyuxiao@sarproz.com so that I can quickly connect and see the dataset.

Hello Yuxiao,

The slaves images are also in the wrong location, just as master, even if the location coordinates dont belong there. From 24 slaves, 22 didnt corregistrated and 2 did (even in the wrong spot). In the link 2 images with no errors in date 04-jan-2016 and 03-may-2016; two with errors 22-mar-2015 and 15-04-2015.

The interesting thing…[Read more]

Hi Antonio,

If you restart the software,
you should get a different message, did you try it?
Something else to try:
(1) open a terminal (2) type ‘hostname’ (3) ping the returned name (eg: ping mycomputername)
(4) if no packets are received, add the name returned by ‘hostname’ to the file /etc/hosts

Thank you for quick response, hope to see the full pixel-tracking function be available soon.

When sarproz process the coregistration,
the estimated offsets are saved in _coreg_offL and _coreg_offS files in the EXT folder.
These files could be loaded into sarproz (by selecting “choose a real file” from the menu that you can find in most modules)
And you could analyze pixel offsets.
However, at the moment these offsets contain also the…[Read more]

Hello Alicia,

I would check the following as a start: the extracted master and slave images. In the attached file you showed me, I can only see the jpeg of master image. Could you also show me a few examples of the slave images? You can find the corresponding jpeg images in the EXT/yyyymmdd folder.

I can see that the master area extracted is…[Read more]

Sorry for the delay, but I want to make 100% sure what was going on. From what you suggest I could find a shift in my images, they all cover my area of interest, however the select area in sarproz area selection option and the area of the master images are different!
The link above contains: master image in jpg, the log file and an explanation…[Read more]

Just to note for other’s reference, this problem has been solved.

It appears that one of the SLC folders was corrupted and does not contain the xml file that is required for reading in meta data.

In the next version of sarproz we will add a folder integrity check for Sentinel Tops folder inside the SLC folder for data import purpose.

I’ve sent it to you.

Please email me your log file at qyuxiao@sarproz.com.

Due to a recent wordpress problem I am not able to see your log file here on forum.
