periz replied to the topic Accuracy of my data in the forum Sarproz Forum 1 year, 2 months ago
Hi,
first of all, to be able to obtain accuracy, we would need the truth, which usually we don’t have. So, it would be better to talk about precision.
In any case, the standard deviation is calculated from the phase residuals (observed interferometric phase after removal of the model you choose for the processing). As a consequence, you can…[Read more] -

I have 2 questions regarding the accuracy of my data.
1. I understand that to obtain the deformation precision in a particular trajectory I must occupy the “stdev” which is the standard deviation.
However, when I obtain the vertical deformation using two trajectories (ascending and descending) in the multi-sensor analysis it only gives me the…[Read more] -

Thanks for your advice,
I was able to run the software by reinstalling the MCR and deleting the cache file.
Thanks for the response.

Greetings of the day!!
Below is the attached screenshot that shows the available mcrcachesir files on my desktop. As proposed by the link it should have been in a folder also there’s no temp folder being created that I could delete. -

1. you did not include all pictures (velocity is not visible). you have to compare all parameters in the same coordinate system (like in sar coordinates)
2. if height and velocity are correlated, something is wrong
3. the range of values to be estimated is too small (both for velocity and height). also, you have lots of images, it means no risk to…[Read more] -

Dear prof. Prission,
Could you please give me suggestion and opinion about my PS-InSAR results?
I have processed 222 Sentinel-1 images from 2015 to 2022 and attached the results. The velocity range is between -3 to 2 mm/year and where we have high height the velocity is positive and the pattern of uplift has correlation with topography. Do you…[Read more] -

Hello forum.
I opened the “main” file (Matlab R2017a_win64 version) and SARPROZ launched properly. Although, when I closed and re-opened it, the software did not launch and the following message appeared:
Undefined function or variable ‘matlabrc’.
And I cannot locate the cashed component of the main.exe.
Kindly guide what should I do?
Thanking in advance. -

Dear managers, I am using Sarproz software to study the 7.8 magnitude earthquake that occurred in Turkey on February 6, 2023. However, although I followed the steps in the Napa earthquake application example, I could not determine the displacement. The data I used are two sentinel 1 images dated January 29, 2023 and March 30, 2023. I am sharing…[Read more]

Hi,
I have a similar problem after processing 109 images from Sentinel 1. I am investigating displacements over an underground gas storage facility using the PS technique. I’ve done the calculations based on the tutorial https://www.sarproz.com/publish/QYTutorial4.pdf. Obtained PS points are shifted as you can see in the attached file. What could…[Read more] - Load More
