hi
here you can see some explanations https://sarproz.com/manual/scegli_dataset.html
just import a text files with a column of values of temperature in Celsius degrees, one value for each image. Ideally, the temperature should be measured at the satellite acquisition time

Hi,
when you get messages as:
* internet access failure
* to start the tool, an internet connection is required
it means, your network has problems, the software cannot access the servers to get the information to start.
it’s a network problem: either your internet provider, or your area, or your country or any other restrictions affecting your…[Read more]

1. please read the forum rules. you must include logs and errors or we cannot help
2. please read through the fourm https://www.sarproz.com/groups/sarproz-group/forum/topic/error-in-main/
3. please update your sarproz version.
any further topics posted without checking the forum, without uploading enough infos, without updating the software will…[Read more]

your network has problems.
change the network or use a VPN

This is a matlab MCR crash, happening while writing a file.
possible reasons:
* the disk is full
* the disk is corrupted
However, other explanations are possible as well. What’s the RAM of your system? Monitor its usage. Possible related reasons:
* RAM is over and you do not have a swap space and/or the swap space is not available/is corrupted
*…[Read more]

the license for windows is different from the one for linux/mac
did you do this?:
1) open a terminal (2) type ‘hostname’ (3) ping the returned name (eg: ping mycomputername)
(4) if no packets are received, add the name returned by ‘hostname’ to the file /etc/hosts

the smart function is a non parametric model, basically a time filter that smooths residuals. thermal expansion is a function of temperature, which has a smooth component in time (like a sinusoid with 1 year period), but also higher frequencies fluctuations. the smart model would compensate only for the smooth component, while actual temperatures…[Read more]

Hi,
1. in the APS module the aim is estimating the APS, not the model parameters.
2. the APS is estimated from phase residuals. phase residuals = original phase – model. if the model is wrong, phase residuals will be wrong and the APS will be wrong.
If you have non linear signals, given the 2 above statements, you should either estimate as well as…[Read more]

there is some conflict between your operating system/hardware/software configuration and the Matlab MCR. Write to support at sarproz dot come and ask for the Sarproz version compiled with matlab 2017. it might solve your issue

hi
you are trying to read a geocoded interferogram. geocoded data should be read with proper tools, as gis engines. or otherwise just import the geotif file in any coding environment, if u have geotif libraries.
leggi/scrivi are functions to be used in sarproz with sarproz-format data in SAR coordinates

From your attachments, the best result is the linear one.

Few hints that work in general (but might not work in some particular cases):
1. when estimating the APS, better to focus on good scatterers, not affected by thermal or non-linear movement. so, using a linear model only is a good choice. you will include other more complex scatteters later…[Read more]

hi,
to become able to recognize correlated results or to spot possible problematic signals, you need training and experience. difficult to help you much with theoretical statements. we should look at your results together and then we could give you some suggestions.
however, here some general hints:
+ it is correct to check that the peaks of the…[Read more]

radar data are complex, not real
so, firstly, u cannot read complex data from jpeg files, u have to read the binary files
secondly, u have to tell “leggi” that data are complex
u do this adding a flag, according to this syntax: https://www.sarproz.com/groups/sarproz-group/forum/topic/aps-processing-4/

hi, check this about phase jumps: https://www.sarproz.com/groups/sarproz-group/forum/topic/burst-lines-on-interfereograms/#post-5462

good that you found the solution. however, I do not suggest you to use the ampl xcorr as default. we’ll try to find out a way to use it only in case of failures.

this is something we need to look at together. let’s plan a conf call via email please

hi,
1. if you want to work on data in the way you describe, you should use matlab.
2. to read data in sarproz (in matlab), you can use the “leggi” function https://www.sarproz.com/groups/sarproz-group/forum/topic/aps-processing-4/
3. using “leggi” you can directly read the original images and perform all what you need without caring about APS…[Read more]

u are exporting geotiff rgb, which is in uint8 values. to export floating numbers, use geotiff 32: https://sarproz.com/manual/plot_par_mod.html

Hi Dominika,
First of all, at the moment we did not think about letting the user pass a manual reference point in the APS module in the command line mode. The sw will load the RefPoint.mat file (the default way it is usually saved), if it is working in update mode. Otherwise, it’s the sw to choose the default ref point. The reason is because in…[Read more]
