Hi Daniele,
you wrote: “use the multi-look factors in the insar processing options.”
where these parameters is necessary to specify?in the menu “InSAR Parameters Selection”, in a group “Interferometric Options”, “Multi-looking Rg-Az” http://sarproz.com/manual/insar_params.html,
or in the menu “Single Interferogram Processing”, in a group…[Read more] -

Hi Artem,
you are right, the choice to give 2 (different) downsampling factors is not very useful there. In fact the software is already outputing square pixels in geographic coordinates (that’s the reason why if you give 2 different numbers, the bigger one is ignored). We will correct it in the future.
So, don’t worry about the shape of the…[Read more] -

Hello,
menu Single Interferogram Processing.
After processing, I’m trying to keep the “height” in the format “Geotiff 32” (Geocode).I choose “Downsampling factors” – 1, 1.
saved a file named – Height_20150702_20150608_1_1_32 (4728 x 11383 samples)I want to make a pixel more “square” and I choose “Downsamp” – 3, 1.

I’d be glad to, how can I contact you personally?

Do you have time to let me remote control to your PC and have a look? (probably via teamviewer, or any other that you would like)

Hi Yuxiao,
I have updated the software, but problem still exists. Once I delete orbit files for some month, I will get errors for every image from deleted month. Broken orbits seem to be downloaded.
I can generate last error and log files for each case, if needed.Jaroslav

periz replied to the topic Improving geocoding results of Sentinel data in the forum Sarproz Forum 8 years, 5 months ago
hi Jaroslav,
about geocoding improvement, up to this moment we used a matlab function in case of need (as you point out, when the GCP is precise, the geocoding is good enough)
this is the matlab function:
set_offscoreg(handles,OffsE,OffsN)
it shifts the data OffsE meters to the West (to East if OffsE is negative)
and OffsN meters to the…[Read more] -

Hello again!
I’d like to possibly precise geocode my results. I remember, that you suggested to manually choose ground control point, but because of Sentinel’s resolution even with manual intervention I can’t put my data together with geo coordinates. There is often some shift. It also doesn’t seem to be possible to use external DEM for ground…[Read more] -

Hello,
Excuse me for late response. I have added missing log file.
Deleting the orbit file from ORBITS/S1A/MM didn’t help. Moreover, every image failed, if I had deleted its orbit file. I am also including last error file with log for error, that occurred after deleting an orbit file.Jarolav

Hi Jaroslav,
your log there is empty and does not contains the corresponding error. Please paste the correct one so I can know exactly what happened.
Based on lasterror.mat, here is what I suspected: An orbit product was downloaded but corrupted somehow and ended in an error. To demonstrate if this is true: since you know the problematic image,…[Read more]

Greetings!
I was trying to get contents for downloaded stack. The problem occured while downloading precise orbits. An attempt to download an orbit file for one of the products ended with fatal error. If I remove problematic product, then everything works fine.
md5sum is correct and I was able to open and process this file with another program, so…[Read more] -

Hi dan,
Forget the above conundrum. All is solved now (but I do not how).
Anyway, the same set of sparse points at different size areas but with similar time series parameters behaves different. Is this normal. If yes, why? -
fbarrio replied to the topic prolem with Spare Point Multi-Image InSAR Analysis (Small Area Processing) in the forum Sarproz Forum 8 years, 5 months ago
No, the sequence is as follow: I closed multi-image insar, changed the area, processed time series again and then I had strange results. I decided to close all the modules (closing down SARPROZ), re-start it again, follow the normal procedure up to multi-image insar, include parameters, press go and then the glimse appears when press results.

Hi Felipe,
I am not sure I understood well.
Tell me if I am right:
– you are in the small area processing
– you processed insar time series (multi-image insar)
– you did not close the time series processing module
– you changed the area (with select area)
– you went back to the time series processing module
– there you got the error
If this is…[Read more] - Load More
