Thanks Nemati.

I will still benefit from your SLC file list to improve the software.

Hi N,

Could you please also kindly pass me the list of SLC files for my debug purpose?

Thanks!

richard-czikhardt replied to the topic errors about get co-registration and get weather data in the forum Sarproz Forum 7 years, 10 months ago

Dear Yuxiao,

I also encountered respective error during TOPS post-coregistration processing plus the one concerning the weather data. However, throughout latest processing of the same dataset, there was no such error. So maybe it is indeed the problem of latest version (23. Dec).

Logfile and lasterror.mat are attached, along with SLC…[Read more]

Hi Dr. Perissin
I am trying to co-register a Stack of sentinel1 images but i got an error, would you pls check it.

ivca-cz replied to the topic errors about get co-registration and get weather data in the forum Sarproz Forum 7 years, 10 months ago

Hello,
I got probably the same error in the last (20-Dec) version, but i ignored it (without counting the number of images, so maybe one or two could be missing, but maybe not) and everything seemed to be allright… this is the problem of the last version. I only checked the coregistered images and they seemed to be ok

OK，The attachment is the SLC filenames. Thank you !

Yuxiao replied to the topic errors about get co-registration and get weather data in the forum Sarproz Forum 7 years, 10 months ago

Hi YaLe,

send me the list of SLC filenames, I need to run your data and browse through all the problems.

Hi,

when I co-registration the sentinel data there is an error said that：Index exceeds matrix dimensions. And when I get the weather data the error said：Attempt to reference field of non-structure array.
The attachmens are the log file and lasterror. Can you help me solve these errors?

Thank you！

periz started the topic Last Sarproz Release in the forum Sarproz Forum 7 years, 10 months ago

Dear all,
many changes have been implemented in the past months.
I give here a brief overview of the major ones.
1) drastic improvement in low level reading functions. In particular, reading a full matrix sparsely is now much faster than before (to test it, use the load mask function and select points applying a threshold on the reflectivity map).…[Read more]

periz replied to the topic Error in Running the main.exe file in the forum Sarproz Forum 7 years, 10 months ago

Dear Mirzadeh,
sorry for the late answer.
The software is telling you to close the application and start it again, I suppose you did it and it did not solve your issue.
Then it should be a java problem. Are you using both IPv4 and IPv6?
try the following:
open cmd as administrator and run:
netsh winsock reset
the launch the software again
let me know

ivca-cz replied to the topic splitting a dataset in the forum Sarproz Forum 7 years, 10 months ago

Hi Daniele,
thank you.
I tried points 2 and 3. With point 2, however, I could not see a difference in the reflmap (it seems to me that it is computed from all the images), but the problem was solved with point 3, with no problem (just warnings) with the master image.

Regards, Ivana

periz replied to the topic splitting a dataset in the forum Sarproz Forum 7 years, 10 months ago

Hi Ivana,
there are several ways to do what you want to do.
1. if you want to process temporary targets, you can analyze the amplitude time series with an on/off model http://sarproz.com/manual/amp_series_proc.html and then use the amplitude as a weight in the insar time series processing frames
2. you can select the images to process in the…[Read more]

Hello Daniele,

(thank you for the implementation of the SRTM download change.)

I am facing a special problem: to split an already coregistered dataset into two, resp. excluding a significant number of images (I need to perform the processing of installed reflectors separately after the data they were installed).

But, in the dataset, the master…[Read more]
