Hi, when I run two SLC images in a single interferometry process, there is any posibility to choose a ref point? its automathic? or isnt necessary?
Best regards,

ewid started the topic Phase unwrapping after APS removal in the forum Sarproz Forum 4 years, 10 months ago
Dear SARPROZ community,
after processing the APS module I didn’t find a way to unwrap this corrected Interferogram. I followed for most parts the tutorial “Atmospheric Delay Mitigation on Single (or few) Interferograms” but I did not do the Multi-looking. I checked the “Stratif.”-Box in the APS-options. I could export it as tif and as jpg file but…[Read more] -

Hi
How SARPROZ calculate cumulative displacemnt 12 mm in that point?
I do not understand
Small area, Non linear smart 5 has used in that calulation -

Can you recommend any paper on non-linear modeling (smart) that is used in SARPROZ
Thank You

Thank You Daniele
I understood it now
Agree, that this is weird, but possible, way to illustrate direction. -
periz replied to the topic Orbit heading in the forum Sarproz Forum 4 years, 10 months ago
Hi Antig,
sun-synchronous near-polar orbits are almost parallel to the north-south direction. However, both when going up (ascending) and down (descending) the satellite path is slightly squinted to the west (as the earth rotates). if you draw this on a paper, and if you take the south direction as reference, u will see those angles (that you…[Read more] -
antig started the topic Orbit heading in the forum Sarproz Forum 4 years, 10 months ago
Hi
I have confusion to detect orbit azimuth value. Azimuth is clockwise angle respect from the North
So in SARPROZ SiteDescription.txt I have AcqHeading values. In my mind heading and azimuth should be same values
But values are
DESC_Heading AcqHeading=-9.3537 deg
ASC_heading AcqHeading=-167.9874 deg1) What those direction values discribe?

Thank you very much for your rapid and detailed answers!
1.
Cons: if your area is affected by temporal decorrelation/changes, keeping long temporal baselines will decrease the overall coherence.
For the cons you mentioned, I wonder if I individually corigester let’s say 50 images ; On the other hand, I select the same 50 images from the 280…

when I have a big dataset of 280 images, and want to process it in several subsets, can I coregister all 280 images one time, and then just select less images to form differenct subsets?
you can, it’s your option. Pros: all subsets will share the same master, so, pixels are directly comparable, you can merge/analyze results and have the full…[Read more]

Hi,
I’d like to ask when I have a big dataset of 280 images, and want to process it in several subsets, can I coregister all 280 images one time, and then just select less images to form differenct subsets?
Is it correct that just keep the images I want in ‘DataSet.txt’ to get the subset combination? I’ve tried by deleting half of the dataset…[Read more]

Hello professor
Thank you for your quick response and accurate.Please let me ask you three questions in this regard
1- How can we calculate time series changes along east -west and vertical velocity for a given point?
2- Is not possible to export e-w velocity and vertical velocity in Multi- Sensor Module or other section of SARPROZ?
3- What…[Read more]
