The case of 2 sensors analysis is an advanced processing mode (as ERS and Envisat combination) that does not apply to your case.
You get only one reflectivity map per dataset.
If you are talking about combining different datasets (as ascending and descending tracks or different sensors) you can combine the geocoded (or orthorectified) maps in…[Read more] -

Hi periz,
I have an additional question. As the manual says：“In case of 2 sensors analysis, two different Refl Maps are processed and saved. They are called respectively MeanFirst and MeanSecond”.
In case of different sensors, is it possible to generate only 1 mean amplitude image for the common AOI？ How to do it ？
thank you again for your…[Read more]

Dear all,
How can I generate a mean amplitude image after the PS stack images are co-registered？
Thank you for your help！

Dear all,
as mentioned in the Sarproz 2019.0 release post, you can now apply some operations to mitigate the atmospheric delay on single (or few) interferograms.
We published the operations to perform in this tutorial: https://www.sarproz.com/2019-tutorials/
Please read it carefully, in particular the note on the last slide: this exercise helps…[Read more] -

steffan started the topic Change Detection error in the forum Sarproz Forum 5 years, 6 months ago
Dear all,
I am processing change detection for image pairs. I am using Normalization. I would like the color scale to be -1 / 1 because I think Sarproz is setting to Min/Max when I use Stretch -> None (-0.6 / 0.6). If I use Stretch -> Absolute Value I get an error:
Undefined function or variable ‘d’
Am I doing something wrong here?

MAC USERS!!
A new MAC compiled version is out: https://we.tl/t-sRQKtKQetN
CAREFUL: this version was compiled with Matlab 2017a!! If you are a previous Sarproz user running the MAC compiled version, you need to install a new MCR version!! Check the readme.txt contained in the tar file above!

Dear Sarproz users,
in recent time we underwent many re-organizations, including worldwide locations, personnel, business model, servers implementation, processing core-functions.
One thing that is worth to mention here is the medium-term plan to set up a permanent SAR/InSAR training center in Italy (those interested in taking courses can start…[Read more] -

Hello,
I also have an issue when trying to check online for an updated Sarproz version. I tried to use different connections, I deactivated the firewall, but the problem is the same, for a few days. Please find attached the lasterror and sarproz log.

Dear Mr. Perissin, we are using SARPROZ software with SLC images downloaded from Copernicus Hub. Should we calibrate these images (for example SNAP radiometric calibration) prior to be processed by SAPROZ?.

periz replied to the topic high negative values in the northern part of image in the forum Sarproz Forum 5 years, 7 months ago
You cannot use the small area processing for such a wide area.
Small area processing is suitable for areas where you can neglect the atmospheric delay (less than 1km for C band).
If the area is bigger, results are not reliable.
You could easily see that by checking the temporal coherence.
You need to take a course on the subject

Hello,
I doubt the Def. trend results of my “Small Area Processing”.
All the images I’ve created have high negative values in the northern part and high positive values in the southern part.
This pattern appears in all my images.
An example is attached to this message.
Is there somebody who knows what causes this pattern?Thank you in…[Read more]
