Def. trend = deformation trend [mm/year] (or velocity or annual rate)
Cum. disp. = cumulative displacement [mm] (it’s the displacement at the end of the time series minus the displacement at the beginning. it’s calculated on the model, neglecting possible residual -not modeled- displacement)

The colored dots in your picture show the deformation…[Read more]

Hi David,
in that plot you can see the red point indicating the location of the pixel you are observing
the blue line is a line connecting the satellite with the ground point
the black line is the local ground profile taken from the DEM you loaded (SRTM by default).
In principle, this is what is plotted, independently from whether it is true or…[Read more]

Hi Mohsen,
thank you for your question

The tool automatically downloads SRTM files from internet

If anything fails, a message is printed but the tool
does not stop running

If a SRTM file is not found, it is created and filled with zeros

To re-download a file that was filled with zeros, delete it (the software will warn you if a
file filled…[Read more]

lat, lon, h (latitude, longitude, height) are the coordinates of the point where you want to calculate the incidence angle
Img is the image relative to the incidence angle you want to calculate
DirSite is the directory of your project

what is that you do not understand, please be specific.

Yours looks like a GCP problem. Chekc the documentation and the tutorials for that.
Now, what you can do is using this function https://sarproz.com/manual/geo_shifts_gui.html to correct it back

You must use the run time compiler corresponding to the version that was used at compilation time
you have no choice
it’s written in the readme.txt file you got with the executable file

The fact that the operation cannot be performed and no errors are reported,
it does not reveal any bugs,
it simply means that the default parameters you are using are not appropriate for your case.
Firstly, you should check the forum.
A quick search would you lead you e.g. the the following…[Read more]

Hi Aleksandra,
if you get an error, send us the lasterror.mat file and the log file. Periodically we have troubles with forum files attachments, but if you make a .zip file containing mat and log files, you should be able to attach it.
Concerning the bridge monitoring, it’s a non-standard analysis which requires some work. Usually we don’t provide…[Read more]

Hi Fatchur,
yours is not the last update. Please update the sw using the manage version module and try again. Should you get again an error, zip lasterror and log files before uploading them

Your comment does not match this discussion, which is around an urban area.
The distribution of the residual height should be at zero, which means, the reference point is close to the external DEM you used, and if you are in an urban area (and the DEM is in fact a DTM), this implies it’s on the ground (not on buildings).
But you are on the…[Read more]

From Minos:
“Hello Marisa,
I had the same problem once.
What you have to do is the following
Go to: C:UsersAppDataLocalTempmcrCache8.3main_… and delete the folder.

Thank you,
we have fixed it

The _mask file tells you where the phase was unwrapped and where it was not
the image with no scale is a bug. we are going to upload soon a fix

I do not know what you mean with “phase ambiguity parameter”.
The phase ambiguity is pi=3.1416… radians
If you convert the phase to height or displacement, you will get the corresponding values. Check any insar paper for the formulas.
