  • hi Ivana,
    InSAR is by definition a differential operation, so, constant terms have no impacts.
    What counts in the temperature is its variation, not its average.
    Also standard deviation and variance are independent from the mean value.

  • Thank you. My aCcess to matlab is now more complicated, but i will try to solve it somehow.

    I think it is sometimes useful to change the master. There are two reasons why I consider it:

    – the temperatures. The master temperature should also be in the middle of the temperatures measured, especially in case where ktemp is neglected (forced to…[Read more]

  • Hi Ivana,
    baselines are saved in the DataSet.txt file. However, it’s just an indicative number, since the baselines changes within the analyzed area. In the processing, such value is calculated from the orbital information.
    If you use Matlab you can also load the baselines values using the command “fast”. They are stored together with other infos…[Read more]

  • Hello Daniele,

    I have a question about changing a master image for an already coregistered dataset. The reason can be e.g. the prolongation of temporal baselines when updating a dataset, to make the master more “central”.

    If I change it in the DATASET SELECTION window, there is no change in DATASET_INFO/DataSet.txt. Is it possible to save it…[Read more]

  • Dear all,
    we just released a new update.
    The main changes relate again to the coregistration process, that underwent a major revision. Several new options are now available, including an improved use of topography, a new independent tiled algorithm (for processing images piece by piece, useful in case of images with variable antenna steering),…[Read more]

  • Hello Dr. Perissin

    The problem was because of my data set, one of the images was corrupted. SARPROZ just works fine.

    Thanks

  • Hi Matus,
    try first the code I passed you by email, we’ll upload it after a few more tests
    thanks

  • Hi Mahtab,
    write an email to me, I will pass you a piece of code which may solve this issue, we need some tests before uploading the complete new version.
    thanks

  • Hi,

    I have problems while updating stack of already processed Sentinel-1 images. The error occurs after “Reramping TOPS Slave Images” starts. Also, I’ve noticed several “Permission Denied” messages under Windows:
    Warning: File not found or permission denied
    > In G:pcodesallocate.p>allocate at 24
    In G:pcodesscrivi.p>scrivi at 175
    In…[Read more]

  • Hello Dear Yuxiao
    I’m using Sentinel-1A images and have problenm in slave extraction step.

    Error files and list of images attached.

    Regards
    Mahtab

    If you check your failing SRTM file,
    it should be very small, you can open it with a text editor, you will see it is actually an html file, not a zip one
    delete it and all similar files, that will solve the problem (the software will download them automatically when needed)
    if you are not sure about which file is good, which one is not, delete all…[Read more]

  • Hello, I have the same problem, I update the software several times by “manage version” (or try because I still have compile version from 29.oct.2016) and the problem with the Invalid zip file “E:IMAGERYSRTMN18W070.hgt.zip”.

  • Hi Jaroslav,
    first of all, take this as a temporary message. We are working at general solutions for avoiding these problems.
    Secondly, when you get such messages, the first thing you should do is checking if this has an impact on the phase.
    The quickest solution is temporarily discarding images that generate this problem.
    Otherwise, the problem…[Read more]

    I think the office’ proxy block the connection :

    Unsuccessful open : Connection timed out: connect
    … A connection Could not be opened, moving forward …
    It looks like non of the servers is accessible. Try again later.

  • periz replied to the topic Problem Loading Sentinel DATA in the forum Sarproz Forum 8 years ago

    Please update your code with the lastest version via the “manage version” module, that you find in the “dataset selection” window. this is a bug that we already fixed.

  • Now the problem comes when I click on “Set Orbit” :

    Here a glimpse:

    Undefined function ‘s1a_get_n_read_orbit’ for input arguments of type ‘struct’.
