Dear users,

a beta-version of the new downloader for the Sentinel-1 orbits is now implemented in the software.
In this version there are some know issues that will be fixed soon. In the meanwhile, please read below for the solutions:

1) in case you receive a message from the server aobut “Too Many Requests”, please just repeat the downloading…[Read more]

Hi Paulina,
to answer your questions we usually take 5 days of classes: those the core topics of multi-temporal insar…
may I suggest you to take the online course? or alternatively we can organize a course in person in your country…

Thank you very much for your response.
So I understand that in order to see the precision of my results I should check which are the components that constitute the coherence?
– Is there any formula or document you could tell me about how it is calculated or exactly what terms affect it?
I understand that my results can be affected by distortion,…[Read more]

Hi all,

While the new repository is implemented, you can try using the Python script sentineleof (https://pypi.org/project/sentineleof/).

Hope this helps.

Sarproz only accepts SSC data: Single Look Slant Range Complex images. yours is MGD, Multi Look Ground Range Detected.

Hi Anti,
here some infos https://www.sarproz.com/groups/sarproz-group/forum/topic/sentinel-orbits-in-sarproz/
usually Sarproz tells you what orbit files are needed, however, I am afraid in this case (change of repository), the error prevents the message from being visualized.
You should manually check the orbits you need and place them in the…[Read more]

Is there any instruction somewhere on where and which files should be placed so that SarProz can find and read them?

Hello, I have been experiencing some issues in updating Sarproz to the latest version. My current version is 2 year old (it’s from the 6th October 2021). I am using the ‘Manage version’ module and I can see that there is a new version from the 2nd November 2023. However, when I press ‘Go’ the Download seems to take forever and nothing really…[Read more]

Hi Emre,
the model you are applying, linear deformation, does not apply to your case, since you had earthquakes.
the suggestion for you is to take an InSAR course (if you want, we do offer InSAR course based on sarproz).
all the best

Hi,
here the concept is the following: when you take an image as a reference, if the image is noisy, the noise is propagated to all other images (being the reference image set to zero, since it’s the difference with itself). This is what you see in that plot.
However, Sarproz takes into account this phenomena and applies some corrections. So,…[Read more]

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]
