you’ll find the zip file below.thanks

please zip the two files and attach the .zip file

This is either related to hardware problem (like e.g. faulty memory) or operating system problem (like e.g. swap space not accessible) or matlab installation problem. Firstly, monitor the resources you are using. Then, you may try to re-install matlab, or the whole system, or run some system/hardware checks…

So, you have ramps both on the estimated height and on the estimated velocity
this is why u see non-zeros velocity.
What I would do is the following:
firstly, check interferograms and see if they are well flattened or if they have ramps themselves. If interferograms have residual orbital ramps, then u can remove them with this function:…[Read more]

Hello!
So this is the link of the files, and hopefully it works. If you need something else, please do not esitate.

Hi Cecilia,

First of all the log is not the correct one and there’s no info in the one you attached.

You can check the site.log and send it to us.

Second, there’s upload error for jpegs due to upload errors. Either send it to us in email (that is in your message) or use a cloud upload like wetransfer.

Then we will try to get a better…[Read more]

Hello, thanks for the answer. Now I tried changing master (20160603), choosing one with better condition. The area is the maximum common, in order to avoid problems. Some of the images are coregisterred, some are not (18 failed out 51 slaves).
A series of warnings appear, including one that says “Reference to non-existent field ‘ra’.”.
The major…[Read more]

Hi Cecilia,

It would be helpful to check the SLC images you’ve extracted.

In FITTED folder you will find 20160311.jpg.

In EXT/yyyymmdd you will find yyyymmdd_VV.jpg for each slave image.

You don’t need to show us all. A few (but make sure you include the master) will be enough to have an understanding as a start.

Q

Hello,
yes well the area that i cropped has a radius of 12km so I thought it would have been ok. I tried to change the master, but still the same. I cannot plot the images because it actually does not the coregistration. I can only see the master and the slave images one by one.
Anyway here there is the log file.

Hi Cecilia,
even if you have to analyze a small target (the dam), you need a minimum number of good targets to guarantee a correct and precise coregistration. Since it’s an extra-urban area, and you are using Sentinel, I’d suggest you to increase the area you are processing.
Moreover, I see in the grabbed screen that the sw warns you about…[Read more]

Dear Perissin,

Can I use CoSSC products to generate Displacement map using SARPROZ? I want to use either TSX1_SAR_SSC data or TDX1_SAR_SSC data from 2 CoSSC products with 11 days temporal difference to Produce displacement, Is it possible to do with SARPROZ software?

Best Regards,
Bala

can you generate a higher resolution geocoded reflectivity map and send it to me by email?
it could be correct and the footprint might be shifted.
if this is the case, the reason is that footprints are geocoded using the elevation of a point in the middle of the area. You have steep mountains in your area, thus the footprint could be strongly…[Read more]
