Thanks for you attention, the Matlab parallel pool is still busy, but waitbar is still 0%.

periz replied to the topic Problems in the APS processing in the forum Sarproz Forum 9 years ago
the parallel processing waitbar requires a network protocol to exchange infos between workers
probably this communication was lost in your system and the waitbar got stuck, blocking the processing.
you can check it if the waitbar does not move and there is no matlab instance keeping the CPU busy.
In such a case it should be enough to restart…[Read more] -

Yeah, you are quite right, I reset the parameters as your recommendation, in which:
1. DL=0;
2. Linear trendI am using a dataset mainly located in the urban area, I re-run the “Sparse Point Selection” and “Graph Creation”, but stopped at “Connection Processing”, the runtime window shows as below
In fact, I do this step in last evening, and…[Read more]

in the advanced parameters you can change the size of the maximum portion of data to process. lowering that number will limit the amount of processed data.
however, in your case you have more than enough memory. I suppose you have an outdated version with a bug.
do you have the manage version module to download a new one? -

you mean you cannot download the precise orbits?
if this is the problem and if you have to do it manually, check the last posts in this topic, to see where to place the files manually downloaded

you need a good amount of patience and experience to become able to play correctly with the parameters and to be able to judge what is wrong in the results.
I do not know the details of your dataset and of the area you are processing, so, I cannot give precise suggestions.
Also, which images graph did you use?
Anyway,
a. why are you setting DL=30.…[Read more] -

Could be, I am playing SARproz on a 4 core, 16GB machine. I am curiosity why the memory leak happen in the middle? Is there a memory control option in SARproz, like the Doris?

periz replied to the topic Problems in the refine co-registration steps in the forum Sarproz Forum 9 years ago
it looks like a memory problem, something that we never saw at this step. how much RAM does your system have?

Dear Prof.Daniele
I used ERS-2 for processing, I want to co-registration, but for “set Orbits” option, the precise orbits unavailable. Any suggestion what must I do?
Best Regards,
Ana

It seems the APS step has trouble. I will put all the screen shot of the setting, result, statistics. Need help for re-run to get modification.
1. The cumulative height of the PS seems has a systemic drift towards big value, which gather above 800m and up to 1000m
2. I check the simulate DEM, it seems all right
3. I tried also the linear-trend…[Read more]

Thanks for your advice, I shall reinstall the right version of Matlab today. Would you take a glimpse of the error file? I will zip them this time.

Before attaching MAT and LOG files, please zip them first.
If the DEM is not well aligned, using the coregistration refinement will mess up your data.
Since you could not choose a GCP because you are using Matlab 2014b, highly probably your DEM is not well aligned.
Generally speaking, the coregistration refinement is needed only in particular…[Read more] -

As you can see here http://www.sarproz.com/pcodes-instructions/
Matlab 2014b and later are not yet supported and the reason is exactly a big change that Mathworks implemented in the graphic management. -

I tried to pursue anyway without manually assigning the GCP. Next step of DEM seems all right, but I do got troubles in the refine co-registration steps, two slave images can not be co-registered correctly with the master, which ends up with two error files. I will attach the error file below.

stevexu replied to the topic GCP selection problems in the forum Sarproz Forum 9 years, 1 month ago
Matlab 2014b is the version, Ubuntu Linux 64-bit is the OS. I tried to skip this step with automatically generated GCPs, but got additional troubles.

periz replied to the topic Importing user defined DEM in the forum Sarproz Forum 9 years, 1 month ago
hi Matus,
the DEM you are showing is clearly smaller than the area you are analyzing.
this is not a good situation, since you are analyzing points where the DEM is not defined.
Which DEM value do you want to assign to the points where the DEM is not defined?
Think about it and solve it using an external tool to manipulate your DEM.
Or otherwise…[Read more] -

if you have problem with the data cursor tool, it’s a matlab problem.
which version of matlab do you have? which operating system? -
stevexu replied to the topic GCP selection problems in the forum Sarproz Forum 9 years, 1 month ago
It turns out only on the not zoomed figure the cursor can be positioned. When zoom in, there will be an random deviation of the capture pixel position and the cursor position. The problems goes:
