For Sentinel, Deramp is automatically done (during coregistration).

Thank you for the information.

It is sentinel-1A data. One interesting thing is that in Site Processing – APS estimation, i generated the graph, and it gives me 25 auto point, and i chose a ‘best’ point with good distribution. Then, i moved to Site Processing -Sparse point processing. When i checked the distribution of the parameters, there is a…[Read more]

By looking at your results again, I notice that the deviation of the estimated height is particularly high: is this Sentinel? If so, the estimated residual height is not very accurate, because the normal baselines are very small. Do not get crazy with the ref point selection.
The suggested ref points are chosen also considering their phase…[Read more]

Thank you so much for the suggestion.

About the reference point choosing, i still have a question. When i read the SARPROZ tutorial ‘Demo: APS Estimation Multitemporal analysis with Sarproz’, it says that best reference point should reflects that both velocity and residual height distribution peak at 0. However, in the Site Processing – APS…[Read more]

hi linweicheng,
sorry for the late answer. You are trying to import Alternating Polarization Envisat images. At the moment this particular Envisat Mode is not supported. We will include it in the near future.

first of all,
velocity and residual height are two different parameters belonging to two different physical characteristics, very different from each other and usually not correlated.
then, even if the majority of radar reflections would be higher than the ground level, still, reflections would be at different height values. Unless you are in an…[Read more]

Sorry that I forgot to upload my attachment……

I’ve also tried to import another Envisat files, but I still met the same problem.

Problems can be solved by doing things step by step from the beginning.

Step 0: read this https://www.sarproz.com/groups/sarproz-group/forum/topic/forum-general-rules/
In particular for what concerns files to include when one encounters errors

correct.
if you are using matlab, you can type “fast” at the command prompt, this will load all important variables and file names. the you can use “leggi” to read the data, with Type=1. here the help:
Data=leggi(FileName,S,L)
Data=leggi(FileName,S,L,[Svet,Lvet])
Data=leggi(FileName,S,L,[Sin,Sfin,Lin,Lfin])…[Read more]

Thank you for the suggestion.

But how can I’ve never used the compiled version yet. Could you please tell me how to open the compiled version, and how to luanch the co-registration in more detail ?

Best regards

sorry, no idea. since it’s the most recent version of Matlab, then the suggestion is to write to Mathworks reporting the error.
to temporarily solve the problem, you can use the Sarproz compiled version. you just need to launch the co-registration in the compiled version, then you can switch back to Matlab for doing the rest. The Sarproz license…[Read more]

yes, this file exist. And the output of “license(‘test’,’Image_Toolbox’)” is 1

is this possibly a compatibility problem ?

Sorry, it seems we overlooked your post…
It sounded a system/permissions problem anyway…
But, never mind, now it works…

This problem is not present anymore with upload version from 31-May, I have successfully uploaded version by manage version module.
Thanks anyway…

does this file C:Program FilesMATLABR2018atoolboximagesimagesprivateresampsep.mexw64 exist?

what is the output of “license(‘test’,’Image_Toolbox’)” at the matlab command prompt?

Please find the attached lasterror.mat

you need to include a lasterror.mat file
