Hi Steffan,
sorry for the late answer. We need to find some time to check your data. We need to see things from the beginning.
For the moment, I can suggest you to check this simple exercise https://www.sarproz.com/yuxiaos-tutorials/
(the last tutorial). It gives you an idea of the results you should see step by step

After reprocessing the point of interest with 135 images, the results are the same (extremes of displacement).
Here are examples:
Here are APS parameters:
Maybe this time series can provide some insight:
Thank you!

Yes you can ignore.
The warning message there should be quite self-explanatory.

Dear periz,
I am reprocessing the dataset with 135 images (from 60 previous), I will post the results soon.
Thank you

Hello Forum,
I am processing 135 Sentinel 1 images. During Slave extraction I get the following error on many images:
S1_STITCHING(): YOUR FIRST 6 LINES FOR INTERFs INCLUDING IMAGE 20170201 WILL BE TOTALLY NOISY DUE TO A FAIL IN ALIGNMENT!
Extract Slave from a different look: date 20170201…Done.Is this a problem or can I ignore it?
Thank you

Hello,
I have downloaded the newest version of Sarproz, and I am working on 48 images of Sentinel 1a data.
Frist, I would like to say that in previous version of SarPROZ I didn’t have this issue and everything worked perfectly (same datasets).During Slaves extraction, I receive this error “Image N does not cover your AOI! Check footprints of N…[Read more]

Yes it works !
Thanks, professor.

Yes, there is surely something wrong.
We should check the APS results -

Hello!
I have been experimenting with a stack of 60+ S1 images from Jan 2017 to Dec 2017. I have followed the tutorials, especially the notes by Mr. Timo Balz, and have completed all the steps with the recommended parameters.
I exported the def. trend to analyse the velocities of the points, and some of them have extreme results (40-50mm per…[Read more]

In all geocoding functions you have a menu and you can choose among kml, geotiff RGB, geotiff 32
The last option exports the actual values and you can load them into a GIS software
Here more infos: https://sarproz.com/manual/geo_sito.html

Dear SARPROZ friends!
SARPROZ nicely presents the phase, reflectivity and displacement maps on Google Earth after geocoding. I wonder how one can get the results (numbers) directly and not in graphical formats. For example, a txt or dat file with latitude, longitude and displacment. This could be much more helpful for further process and…[Read more]

periz replied to the topic Displacement along line of sight and satellite track azimuth in the forum Sarproz Forum 6 years, 3 months ago
the displacement you detect from InSAR is along the LOS.
To get displacement along track, you may use pixel tracking.
We do not have yet a proper specific module for pixel tracking, but you can still perform it.
Here an exercise showing how to apply pixel tracking (the third tutorial):

Dear friends
So far I could generate a displacement map from the Sentinel-1A SAR data with VV polarisation. However, what I need is the displacements along the LOS and Satellite along track. How can I extract such information from SARPROZ.
Is there any way to combine different InSAR data, for example, ascending and descending tracks to…[Read more]

Hello ogokce,
A new version of sarproz is available and please try to give it a test. The bug should be gone.

Hello ogokce,
I believe what you are seeing there is a bug as we are working on some new updates in the change detection module. We will work on that and let you know when the bug is fixed. Meanwhile, I am glad to hear that you can still use the other way around to solve it.
I will keep you updated.
Yours,

ogokce replied to the topic Change Detection Menu – Reference to non-existent field 'DC' error in the forum Sarproz Forum 6 years, 3 months ago
Update: As it was described in the tutorial, I used “load mask” and “visualization tools – Scatter Plots”. It solved my problem when I changed x axis to longitude, y axis to lattitude and press GeoOut. There might be a bug in change detection menu but this “visualization tools – Scatter Plots” tool saves the day. Thanks…

Hello,
I tried to follow same procedure in Yuxiao’s Tutorials – QYTutorial1.pdf. Everything was OK until data export to Google Earth. At that point, after selecting “Orthorectify” in Mode, and pressing “Go” to export results to Google Earth, an error occurs: “Reference to non-existent field ‘DC'”
Log and last error is attached.
Best regards. -

inside the SLC folder
you should have a directory for each image
each directory should contain all original files (img, led, trl …) - Load More
