periz replied to the topic APS processing in the forum Sarproz Forum 7 years, 2 months ago
Hi Venera,
1. update your software version: it’s old. An example: selecting asymmetric ranges of values in the APS module is wrong, now the sw does not allow you anymore to choose that
2. The Auto Graph works very well in urban areas to select flower centers on the ground. However, I don’t think it’s a good choice in your case. simply use a…[Read more] -

Try to see if updating the sw solves the problem (via manage version)

You should attach this log: H:kwekwesite.log, the one you sent is empty.
And the lasterror.mat is not corresponding to the error you reported above: lasterror.mat files are overwritten if multiple errors occur. To avoid loosing them you can insert your email address in the advanced parameters: you will receive an email for each error, with log…[Read more] -

periz replied to the topic sarproz crash in the forum Sarproz Forum 7 years, 2 months ago
This is either related to hardware problem (like e.g. faulty memory) or operating system problem (like e.g. swap space not accessible) or matlab installation problem. Firstly, monitor the resources you are using. Then, you may try to re-install matlab, or the whole system, or run some system/hardware checks…

periz replied to the topic APS Processing parameters in the forum Sarproz Forum 7 years, 2 months ago
So, you have ramps both on the estimated height and on the estimated velocity
this is why u see non-zeros velocity.
What I would do is the following:
firstly, check interferograms and see if they are well flattened or if they have ramps themselves. If interferograms have residual orbital ramps, then u can remove them with this function:…[Read more] -
periz replied to the topic Not enough points! Aborting! -Coregistration- in the forum Sarproz Forum 7 years, 2 months ago
Hi Cecilia,
even if you have to analyze a small target (the dam), you need a minimum number of good targets to guarantee a correct and precise coregistration. Since it’s an extra-urban area, and you are using Sentinel, I’d suggest you to increase the area you are processing.
Moreover, I see in the grabbed screen that the sw warns you about…[Read more] -
periz replied to the topic Problem with GCP selection and Geocoding in the forum Sarproz Forum 7 years, 2 months ago
can you generate a higher resolution geocoded reflectivity map and send it to me by email?
it could be correct and the footprint might be shifted.
if this is the case, the reason is that footprints are geocoded using the elevation of a point in the middle of the area. You have steep mountains in your area, thus the footprint could be strongly…[Read more] -

Can you be more specific about “you have tried with ext. DEM and it’s not working”? what did you do and what is not working? If you got errors, can you paste zipped lasterror.mat and log files?

periz replied to the topic Error in importing RSAT2 images in the forum Sarproz Forum 7 years, 2 months ago
both directories have no problems.
the sw searches for the file product.xml. if it is not found, it will give the message you reported above.
be aware that the directory you have to select in sarproz is the one containing (not contained!!) the SLC folder.
“Qarn16” and “qarntest” in your case -
periz replied to the topic Problem with GCP selection and Geocoding in the forum Sarproz Forum 7 years, 2 months ago
hi Bala,
the “force my pixel” option simply means that the software is not checking the probability that the pixel you selected is actually corresponding to a radar target. You can use it in the case of glaciers.
Here the problem is the external DEM. When you say that the height is zero, I assume that there is no SRTM in your area. Is it correct?…[Read more] -

narginchk has been introduced in Matlab 2011b
I guess then that you have an older Matlab
for compatibility issues we’ll remove those lines
for the moment you could overtake the problem by using a more recent version of matlab… can you? -

can u please post the structure of your directory?
where is the product.xml located precisely? -
periz replied to the topic Weather data download problem in the forum Sarproz Forum 7 years, 3 months ago
Hi Pawel,
we could change that piece of code to allow you using that function with your old matlab version.
However, you may find other issues later on. If it is easy for you to upgrade matlab, please do it. If you cannot, let us know and we will make those changes

periz replied to the topic Error on "Dem visualization" in the forum Sarproz Forum 7 years, 3 months ago
Those are not errors
they are informative messages.
If in your area no SRTM files are available, there is nothing wrong. If SRTM should be available, then the software cannot download them for some reasons. Do it manually and place them in that folder -
periz replied to the topic pcodes installation in the forum Sarproz Forum 7 years, 3 months ago
hi Thibault,
to use Sarproz in matlab, you need the pcodes, which is a set of more than 1,500 files with extension .p, and which comes in a zipped file, pcodes.tar. If you have the main.exe file, instead, it means you have the compiled version that runs independently from Matlab. You cannot call main.exe from within Matlab.
Please send an email…[Read more] -

Dear Bridget,
it is always useful to include the full log file in order for us to read more infos and better understand your case.
It seems to me that both issues should belong to an old software version, the last update should have solved them.
In any case, none of them represent a real problem for the success of the processing.
Please check you…[Read more] -
periz replied to the topic Using for two different study area in the forum Sarproz Forum 7 years, 3 months ago
is this error happening in both matlab windows or in just one of them?
I am afraid this is a problem of that particular matlab version.
We tested it with versions equal or higher than 2014a and it works -
periz replied to the topic Using for two different study area in the forum Sarproz Forum 7 years, 3 months ago
are you opening two matlab windows and running a sarproz instance in each of them?
