Hello Daniele,

I’m interested in getting this information too. I exported the Synthetic Amplitude via the Time Series Module and would like know whether its values are the normalized ones you mention to Ivana.

I enclose the created CSV file. As you see the values for the first date are always 0. Why? Is it the Synthetic Amplitude the correct…[Read more]

Hi PY,
I had a feedback from an other user who met the same problem. But he has 2 computers, and it happens on only one of them. It looks like it is related to openGL. At this moment I have no more clues, I’ll let you know

Hi Yasser,

you will need to zip the lasterror.mat together with the log file and upload the zip file so that I can take a look.

Thanks!

Hi PY,
is this happening after a sarproz update?
if so, would you mind switching back to a previous version and try if that solves the problem?
without any other information, it sounds like it’s a system/matlab problem…
could you single out any other software/system change on your PC? Maybe related to Java?
We may need to investigate it directly…[Read more]

ok, now I understand the issue.
in fact, we did not consider this situation, we will modify the code for that.
The fact is that you are multilooking. as a consequence, the “Amp. Stab. Ind plus Sp. Coher.” is useless.
in fact, the amplitude stability index is a full-resolution index. if you multi-look, it makes no sense using it…

this is laterror.mat and log files

I run the coherence map generation again, the message is

Coherence map processing started

loading Graph_0290.mat graph

allocating 190 x 224 samples, type: 0

save_asi_coer: Firstly, process the Spatial Coherence! Aborting.

The Processing concluded successfully, here a specific message:

Coherence Map Generation : job ended
why…[Read more]

the message u posted states that the “Amp. Stab. Ind plus Sp. Coher.” parameter is not found.
Such parameter is generated when you save the Spatial Coherence.
So, my suggestion is: run the coherence map generation again. I expect that in this way you will solve the problem.
If on the contrary the “Amp. Stab. Ind plus Sp. Coher.” will still be…[Read more]

Hi Yuxiao,

I am sorry, I did not mentioned the path where the lasterror is. Hope it is fine now.

Thank you for the answers. I will therefore try to re-download the data in all cases. The distance is not so critical, I was just astonished that for two tracks, the stations are so far away from each other…

When the weather data was not complete…[Read more]

Hi Ivana,

For your second question: since the software is querying one webpage for each date of your image, there are chances that one or more of all the querying are not getting response within the setted time limitation (which is 10 seconds, I think). The reason we set the time limitation for each query is because there is a known bug in Matlab…[Read more]

Hi Ivana,
yes, the your first note is a bug. please give us 1 day to upload the fixed version.
Second note: if you download the weather data at the beginning of the SLC extraction process, yes, the center of the footprint is used. But if you download the data again after working on the crop, the crop center is used. If still the weather station is…[Read more]

As checked together,
probably there were corrupted files in the optical images directory, changing the directory or deleting/moving the downloaded Google Earth files solves the problem.
We take the chance to remind here that GE files are downloaded in this directory: ‘../GIS/GOOGLEEARTH/’
with reference to the current site directory.
In case of…[Read more]

Hi Ivana,
that error happens while loading the image in the background.
The sw searches in the directory that you can change through the “layer” button.
If you change the directory, you should temporarily solve your problem.
To investigate why that happens, you could save the small area (with the same conditions as when the error occurs)
and pass…[Read more]
