is the image flipped? are you using the most recent updated version of sarproz?

upload on e.g. wetransfer and paste a link

right, for some reasons I forgot to answer.
Well, the easiest way for you to select manually points is to create manually a mask file.
You can do it in the following way:
– type fast in the matlab command prompt
– create vectors of samples and lines of the points you want to analyze:
Svet=[ … ]; Lvet=[ … ];
– create a matlab sparse matrix:…[Read more]

Images are equalized via a simple normalization process.
You need it to perform statistics on amplitude time series.
The unit of amplitude is volt. But its value is useful only if compared to other values, not in an absolute way.
If you could calibrate it by knowing the amplitude of a reference corner reflector,
you could derive the RCS of targets…[Read more]

First of all,
can you update the software version?
You do it through the manage version module, in the dataset selection window.
Then try again and if the problem persists, can you send us a link for downloading your LED file?

I am afraid we need to check the data together
Can we talk on skype?

Thanks Ivana,
it has already been corrected in the pcodes version
we’ll upload today also the compiled ones

If you want to get it working, please read the messages given by the sw.
The sw always tells you what’s going on and whether anything is wrong.
In case of unexpected errors, all error details are saved in a .mat file.
If you want to get assistance, zip .mat and .log files and attach them here.
If no errors occurred, just zip and attach the .log file here.

Ivana,
first of all, a general comment: you have all needed tools to investigate your problem…!!
You can plot the DEM in geographic coordinates, and you know you should expect 4 black crosses that give you an idea about where is the footprint of your data w.r.t. the DEM. I do not see them in the picture above, and this should be a first sign…[Read more]

If you don’t understand Matlab,
then maybe not much to do…

I try to give you a hint to read the message shown by disp_err in any case..:
The list of files tells you the inter-dependency between them (the sequence of calls) at the moment the error occurred.
The list starts from the upper level.
You were in Site Processing (“analisi_sito”), you…[Read more]

Hi Ivana,
the error there is related to the SLC data module (by the way, to check it, you just need to type “disp_err” at the matlab command prompt -if you work with the compiled version, just copy the lasterror.mat in the working directory of any Matlab session [disp_err.p works independently and even without license]-).
Sometimes it may look…[Read more]

you insist willing to include dependent pixels, and this is a clear example that dependent pixels create only problems, without increasing a single little bit the information that you can extract
in that plot you have 2 scatterers, one covering 3 pixels, the other one covering 2 pixels
the height you estimate is fake, because it’s pixel…[Read more]

type “fast” in Matlab
and then use the following expression
[Rg,Az]=geo2SAR(lat,lon,h,el,Master,handles.SiteParam.DirSite);
el=1 corresponds to WGS84
otherwise input a string like GRS80 or the ellipsoid you need

to extract phase/amp values the easiest way is to use the small area.
when you load a small area, complex numbers are accessible in the…[Read more]

We are working at stitching subsequent images together. Up to now Sarproz never did it, we always worked with single footprints.
The reason for renaming images acquired on the same day was a quick and dirty solution for managing TanDEM-x bistatic pairs without changing the naming convention.
What you can do at this moment is working on them…[Read more]

the “smart” function implements a non-linear analysis, so, it is clear that the linear velocity will not be estimated
use the Cumulative displacement instead.
consider anyway that here the key point is the estimation of the height.
after the smart, you could repeat the analysis reading the height previously estimated and estimating a new linear…[Read more]

1. that is no “software error”. it’s a message about terms called “master error” and “reference error”. if the software returns an error you get the usual messages “an error occurred … lasterror.mat was saved …”
2. probably you clicked on a pixel which is not a PS. but as I can see from that attachment, a PS IS selected and its parameters ARE…[Read more]

I am afraid this is an overfitting case.
I suppose you do not have many images, so, in such case I do not suggest you to estimate the thermal expansion.
Also, keep height and velocity ranges small in the APS estimation.
Better you remove high points when estimating the APS.
The APS estimation process should be kept as simple as possible. Later in…[Read more]

I am tempted to answer in the following way:
whatever the initial PSC you select, there is no better way to identify the good targets as with the temporal coherence. That is, the best way to state if a point is reliable or not is to look at the phase dispersion after analyzing the connections. With “analyzing the connections” I mean processing the…[Read more]
