seweryn started the topic Reading Amplitude in dB And Phase in the forum Sarproz Forum 1 year, 8 months ago
Dear PeriZ team,
I’d like to have amplitude values (intensity) for each pixel of my SLC images and convert them to amplitude-dB, would you please update me after coregistration, which files needed to be read in Matlab and how? or does SARPROZ has this functionality itself?
Also I need to read phase values of each image and each interferogram, so…[Read more]

Hi Mahtab,
https://www.sarproz.com/groups/sarproz-group/forum/topic/orbit-heading/regarding your formula, you should check the source from where you got it. and if you know the relation between two angles, you can simply replace the angle in the formula with the other one
here you can see similar discussions…[Read more]

Hi,
I have a question about the orbit heading angle that SARPROZ gives us. In the SiteDescription.txt file for a time-series in Ascending orbit, I see AcqHeading: <<-169.7791>>.
Is this Acquisition Heading angle the orbit heading angle? if so, I expect for an ascending orbit, the orbit heading angle (αh) should be the blue angle as plotted in…[Read more] -

periz replied to the topic lat/lon for each pixel in the forum Sarproz Forum 1 year, 8 months ago
the answer from Anti (exporting the extended -raster- image) is a possible solution
alternatively, you can export sparse data -like a vector- for a selection of points. if you select ALL points, you will select lat/lon coordinates for all points.
in any case, I suggest you to take the sarproz course. write to courses at sarproz dot com if interested.

Export image that you are interested to geotif
Then use, for example, gdal to translate tif file to csv. It should be possible to do in Qgis to -

Dear PeriZ team,
I need to track how amplitude and phase of one pixel is changing in my S1 dataset. I have done the coregistration for my SLC S1 images and I’d like to know lat/lon of each pixel to find the exact location of my feature in SAR coordinate, I know that in the siteprocessing module we can do geocoding and after that Lat.mat and…[Read more]

periz replied to the topic Quasi-PSI processing details in the forum Sarproz Forum 1 year, 9 months ago
Hi Zahra,
firstly, few general comments:
* there is no perfect solution that works in all situations. you have to choose the proper solution given your particular situation
* the secret of the best InSAR expert is being able to look at and read the data. only afterwards one can properly choose the processing options
* we try to teach looking at…[Read more] -

Hi,
I’ve done a QPSI processing using my 2.5 year S1 images, and only found a few points around my small case study, at the moment I am working on different things (working around thresholds etc) to help to increase the density. Could you please let me know if you have any specific advice or suggestions on bellow:• MT adaptive mask: I sel…[Read more]

1. you can do all the processing you want in the same project, just you need to keep track of what you do. e.g. if you firstly estimate the velocity in one method, then make sure you do not mix the result with the velocity estimated in an other method. how do you do that? by choosing “replace” when you save the results. the sw makes a backup copy…[Read more]

Dear periZ developer,
I’d like to do some different processing with same data sets, including PSI, QPSI and DInSAR (single interferograms). I know that the preprocessing should be the same including master and slave extraction, coregistartion and preliminary analysis and geocoding. could you please let me know how I can use the same SLC folder…[Read more]

I read that post but didn’t really understand it. If my AcqHeading in SARPROZ is -11, then according to the previous post, on a 360 degree circle, that would correspond to 169?

periz replied to the topic ManualLims in the forum Sarproz Forum 1 year, 10 months ago
This is an option that can be used only in the Command Line Mode and it allows extracting an AOI based on given Input SAR coordinates. ManualLims is a row vector made of 4 elements: Sin, Sfin, Lin, Lfin (where S stays for samples -range- and L for lines -azimuth). When ManualLims is given, other inputs for AOI identification are neglected

I have a similar question for heading angle, for AcqHeading in the dataset description. Why are the angles negative?
