Additionaly, I suggest to use Graph Analysis and Refinement module. It is between APS and SPP button. There is possible to remove low coherence connections and improve APS graph.

Ho big is Your bridge. I it is less than km You may skip APS and use small area module

antig replied to the topic burst lines on interfereograms in the forum Sarproz Forum 5 months, 2 weeks ago

I solved the problem myself.
the problem was in coregistration.

Firstly I used “only orbits” mode for coregistration.
After analyse of Site.log the program had gave warning to that in coregistration has some thing wrong.

I tried “Ampl Xcorr” mode for coregistration and it worked match better. No warnings, No Stripe

So in future I use “Ampl…[Read more]

antig started the topic burst lines on interfereograms in the forum Sarproz Forum 5 months, 2 weeks ago

I generated an interfereogram from two Sentinel-1 phase images. In the interefereogram (Burst_line.png) has clearly seen stright lines that match bursts stich lines. I would like to fix it. What are the tools in SarProz to fix this kind of problem. I use compiled version.

Thanks for answer

antig replied to the topic Unwrappin APS phase values in the forum Sarproz Forum 5 months, 2 weeks ago

You may set in module “Insar params” appropriate settings
Do not filter and multilook interferograms check “Flattening” and “DEM remove”
save settings
genereate interfereograms in module “interferograms protsessing”

Hi
I found good news from JAXA
https://www.earthobservations.org/article.php?id=392

Does anybody knows which site it is possible to download

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

antig started the topic No linear model in the forum Sarproz Forum 1 year, 1 month ago

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.

antig started the topic Orbit heading in the forum Sarproz Forum 1 year, 1 month 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 deg

1) What those direction values discribe?
2)…[Read more]

Program warns that there are voids in used ext.dem model (NaN values). Does it interpolate then Nan values or do nothing?

antig replied to the topic Sentinel precise orbit download in the forum Sarproz Forum 2 years, 2 months ago

I don’t understand. Where is no such warning discribed in forum (I searched). And no lasterror.mat also because this is a warning not error

Hi and Happy New Year

If SarPROZ download Sentiel 1 precise orbit then I got warning

what units?

antig replied to the topic Amplitud stability good but low cohherence in the forum Sarproz Forum 2 years, 2 months ago

Where I could find seasonal model that You mentioned. Thermal I found but how it use?

antig replied to the topic Polar mode (9) error in the forum Sarproz Forum 2 years, 2 months ago

I have deleted manualy all *-vh-*.tiff (not needed for interfereometry) files from all “rawdata”.safe/measurement/ catalogs. if you go /slc/ catalog you saw the raw data catalogs. Then try again.

Hi again
I have realy hard to understand thats happening.
i have stack of sentinel 1 images and I mada Small area PSInsar analysis. Estimating booth LT and H.
In result analysis may seen that major H residuals has positive values (out.png).As I understood correctly, then H should be Ex.Dem+residual H. So Relative height from ground should be…[Read more]

antig started the topic Split stack in the forum Sarproz Forum 2 years, 5 months ago

I have ~2.5 years stack coregistrated. If I need it to split 1 year, 1.5 year 2 year , 2.5 year starting latest image.
One possibility is make five indipendet projects but it takes time. Is it in SarProz other possibilities?.
I’ll tried play in temporal baseline time but it works only if master is included(understandably).
