Hi Daniele,
Yes…you right. previously I just direct to pcode by changing its directory in MATLAB windows. now, I try to make a shortcut and started. pcode working well.thanks a lot.

This is not a coregistration error, it’s a java problem
are you sure you are starting matlab from the pcodes directory? -

Thanks so much for your response.

EXT folder, there is a directory for each image
inside those directories you can find a text file yyyymmdd.meta (careful, there is also a .meta.mat file).
You can derive R0 from the Range Start Time that you find there.
otherwise, type “fast” in matlab (without quotes) hit enter and then:
R0=leggi_img(handles.SiteParam.DirSite,Master,{‘R’}) -

Hi
How can i find the slant range(R0) from the sensor to the ground, in the software?Thanks and best regards

Sure, a have attached a sample kml file.
Thank you! -
periz replied to the topic Custom mask generation with multi geometry doesn't work in the forum Sarproz Forum 6 years, 9 months ago
At the moment you can use a polygon at a time and generate 2 masks. Then, either you merge them in matlab or you can use the scatter plots and say “mask1 or mask2”. if you send us the kml, we’ll improve the code for importing MultiGeometry objects

Hello!
In custom mask generation module, if I load a kml file containing MultyGeometry object, then the software generates an empty mask.
Is there a way to generate one mask for two different polygons?Jaroslav

dora replied to the topic Problem with external DEM in the forum Sarproz Forum 6 years, 9 months ago
Hi,
the DEM file didn’t have a coordinate system attributed. I corrected that, it is in WGS84, but I still get the same error. DEM visualization is ok, but I can’t check the external DEM in SAR coordinates. I get an “empty matrix” message (I am attaching the site file as well). Besides, I get several “out of memory” messages. I already decreased…[Read more] -
periz replied to the topic Coregistration Refinement in the forum Sarproz Forum 6 years, 9 months ago
The coregistration refinement is doing 1 single operation:
it is taking the external DEM and it is using it to resample the image by correcting topographic distortions.
In other words, the sw is not going to re-process the cross-correlation between patches, this was already done during the initial co-registration (and this is the reason why it…[Read more] -

periz replied to the topic Problem with external DEM in the forum Sarproz Forum 6 years, 9 months ago
To check if the process was well concluded,
you just need to plot the external DEM in SAR coordinates with the “view parameters” function.
Also, to check your original DEM, you should plot it with “DEM visualization”.
But surely the process failed, if you look in the log file, you got a considerable amount of errors.
Probably your DEM is in UTM…[Read more] -

Dear all,
I got this error “Interpolation requires at least two sample points in each dimension” at “External DEM and synthetic
amplitude in SAR coordinates” (files in attach). What can I do to solve this? Despite the error, the button is green. Is it ok to continue or is this something that will lead to problems later?
Best regards,

I took two points spatially close (ca 200m distance). Because the area per se have not so many points.
Unfortunately, I do not know anyone close that can help me. I am doing this project basically from zero.
But ok thanks I will try to improve the resolution then -
periz replied to the topic Combine different geometries for decomposition of LOS motion? in the forum Sarproz Forum 6 years, 10 months ago
A first question would be: did you select points representative of the area where they are located or did you choose outliers?
Secondly, the software decomposes asce/desce velocities only on AD pairs. AD pairs are points located closely in A/D datasets. The sw selects them based on your inputs (AD processing) and based on the corrected shifts…[Read more] -

Let’s see. In the figure attached , there is the East -West velocities from the module. Blue is positive so East. So far so good.
But I took one descending point which has final trend of -20mm/year (the “typical” value you get in the small area processing), and one ascending point value of -7mm/year. So both negative.
The points are located in a…[Read more] - Load More
