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!

periz replied to the topic Plot problems in the forum Sarproz Forum 8 years, 3 months ago
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] -

Dear Dan, Yuxiao,
I am currently processing TSX data.
In the APS processing when I click on Plot (after Sparse points selection) nothing happened.
I have to kill Matlab.
All the plot functions in the APS, PS are not working for me as well as the plot button in the Scatter plots.
I am using Matlab 2014a and the latest pcodes.
I don’t have any…[Read more] -

Hi all,
Sorry for the slow updating progress for Sentinel S1A module during the past semester. In the next new update of sarproz there will be a major update for Sentinel S1A module. The new one includes the following major updates:
(1) Sarproz will automatically read precise orbit file (with a standard deviations of less than 2.5 meters) for…[Read more]

periz replied to the topic Amp. Stab. Ind plus Sp. Coher in the forum Sarproz Forum 8 years, 4 months ago
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… -

periz replied to the topic Amp. Stab. Ind plus Sp. Coher in the forum Sarproz Forum 8 years, 4 months ago
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]

Yuxiao replied to the topic Weather module in the forum Sarproz Forum 8 years, 4 months ago
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] -

Hello,
I am not able to load my own temperatures after downloading weather, error attached.
Some more minor notes to the weather module (not critical):
– the weather (as it seems to me) is downloaded from the stations close to image center, not the center of the crop, for different tracks (one area), the weather stations are more than 150 km…[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.

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] -

periz replied to the topic original PS method in the forum Sarproz Forum 8 years, 5 months ago
Yasser,
In Sarproz you can implement almost everything. However, instead of having buttons as “PSI”, “SBAS”, or whatever, you have a series of tools/options that you can combine. Clearly, this requires understanding the operations. It’s more difficult than having predefined buttons, but I think it’s more powerful.
The 2 conditions you mention…[Read more]

periz replied to the topic original PS method in the forum Sarproz Forum 8 years, 5 months ago
Hi Yasser,
original PSI: STAR graph, no weights, no filtering
QPS: non-STAR graph, weights (spatial coherence), filtered phase
Anyway, Sarproz gives you the choice to combine those options and do what you want. You do not need to call what you do “PSI” or “QPS”.However, you have to be aware of the following: when you choose the option “coher”…[Read more]
