ewid started the topic Phase unwrapping after APS removal in the forum Sarproz Forum 4 years, 9 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…

periz replied to the topic Big dataset processing in the forum Sarproz Forum 4 years, 11 months ago
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]

Hi,
for some reasons it was not recorded if your dataset was ascending or descending.
We now added the possibility to manually fix this missing info.
Later today or tomorrow update again your sw with the last version.
follow these steps:
1. open the multi-sensor module
2. load the asce and desce TS objects.
3. if the pass is missing (3rd field)…[Read more] - Load More
