SARPROZ ©

Hi,

try to draw the angle to the piece of paper. You will realize that the value -129.6 deg is not the heading of the satellite track, while the value from SARPROZ is really heading angle of the satellite from the North (azimuth angle).

best,

ok,

so, I have tried this – i used the same master and put only 4 wrong slaves in a “test” project.
Two of them were extracted (normally?):

Thank you Yuxiao, in the meantime I tried something else:

I have removed the corrupted files and removed also these wrongly cropped images, re-extracted slaves and – it is working normally now..

I would like to recommend some test for corrupted files. Also, I don’t understand why the presence of one corrupted file caused that another file was…[Read more]

Hi Yuxiao,

thank you.
So, I have realized that the coreg-erroneous slave images are cropped from totally different area!
(it is strange, even the jpg previews were not generated, i had to do it manually and saw that they are after Slave Extraction from totally different location.. please note that I use precise orbits normally here…)

Let’s try…[Read more]

only adding a comment – the coregistration errors are accompanied by following message:
Error in amp_corr(): Match parameters missing!

do you have any clues?
thank you

hi Dan,

thank you very much. I have recreated the Image.conf using the command you wrote me. Everything works well now.
I will perform the same processing steps in another area to see if i can recreate the error. Anyway, it can be also again caused by the permissions due to my VM system, maybe due to accessing the structure from…[Read more]

hi,
I have tried once more (with another S-1 dataset) the SLC update process.
Unfortunately, it again failed – can you give me some advice about what can be the cause of these problems?
This time I had in my SLC folder all the previous data and only provided new 5 images..

seems working – thank you very much! m.

ok, i see now about the attachment – thank you.
ok, i will try pcodes

ok, again the extension was blocked – what filetype should i send you? .zip?

well, it seems i cannot send .mat files, sorry (security reasons?)

hi,
so the answer is to forget auto GCP and always geocode manually?
ok, thank you.
