SARPROZ ©

Hi Jaroslav,
at the moment, Sarproz saves the 25 reference points in a temporary variable. That variable can be accessed if you run Sarproz in Matlab using the pcodes version. You can access it if you type “fast” in the command prompt when Sarproz is running and the APS module is open and the function for automatic selection of reference points…[Read more]

the tif file is a 3 channels product. the inputs of the 3 channels (which you can pick up as you like) are all products that can be loaded in the scatter plot module. not as a color clearly (which has to be a scalar), but you indicated you wanted to threshold the MTCD product. so, in the boolean section of the scatter plot module you can implement…[Read more]

Hi,
regarding your first question, the outputs of the multi-channel change detection module (shortly described here https://sarproz.com/manual/rgb_module.html) are common outputs that the radar community knows how to interpret. Usually, those outputs are evaluated visually. If you want to set thresholds, you have to build them yourself, e.g. via…[Read more]

if you want to make your own code making your own choices automatically, you are very welcome. you can load the autoconnex.mat in matlab and check all estimated parameters. names should be self explanatory. if you have questions just ask. then you can save the reference point and load it afterwards. you can do it also from the command line.

Sarproz automatically selects the best reference point according to a number of criteria, including those you mentioned.
Nevertheless, in the Sarproz course, we teach how to judge the goodness of the reference point and what to consider to pick up a good one. In most cases, the automatic one is good enough. In some particular situations, the…[Read more]

data are in a folder like : “c:my project”
you should rename it in something like “c:myproject” or “c:my_project”

Hi,
this is a topic discussed in the course, which I strongly suggest you to take. Generally, better not to estimate the thermal expansion at the APS processing stage. Instead, use a linear model and then estimate the thermal expansion in the MISP module. However, if your area is full of high buildings, (and if you cannot manage picking up points…[Read more]

Hi,
please check well the forum before posting questions
you can read all data in Matlab, images and interferograms. Just notice both are complex
Here you can find similar discussions and more links to some explanations about reading data using “leggi”

Hi Mahtab,

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]

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.

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]

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]

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

hi
usually, when you get license problems, the software tells you to send the license.key file to licensing at sarproz dot com. they will tell what is the problem related to your license
it seems anyway that your license.key file is corrupted. if the compiled version is working on the same workstation, copy the license file in the compiled…[Read more]

Hi there,
you want to manipulate data in a custom way, you are welcome to do that. You just need to read the data (e.g. in matlab) and then apply the processing steps you wish.
Here some hints to read the data in matlab:

Hi,
the section is containing the LOS, perpendicular to the azimuth direction (flight path)
