    Hi Periz,

    I viewed the reflectivity map with 1×1 downsampling from (Extended geocoding). There appears to be a slight shift (several metres) between the reflectivity map and the actual structures from Google Earth. Do you think this can/should be improved by choosing better GCP?

    Thank you very much!

    Hi Periz,
    Thank you very much for your response. I do think it is related to a faulty memory as I recently added an 8 GB RAM which could have caused this issue.
    Anyways, The problem does not happen that often recently, but if it persists I will definitely try what you suggested.

    Thank you very much for your help. I really appreciate it!
    Regards,
    Moath

    I also have two more questions:

    1- Although the results obtained after residual orbit removal were better, there are still interferograms that are affected by ramps (see attachment). Could this still have influence on my results?

    2- The other issue is with the GCP selection. I identified a lamp post as a GCP and when opening mean KML, everything…[Read more]

    Hi Periz

    Thank you very much for your response.I checked the interferograms and they had ramps. I obtained better results (please find attachments) when I used the function you mentioned the the parameters you specified.

    Is there a way to know how good these results are?

    Many thanks
    Regards,

    Hi,

    I have been struggling with this issue since I started using sarproz. The software crashes randomly, most of the time when doing the APS estimation and sparse points processing. Please find the error message as well as the error report in the attachments.

    Thanks a lot!

    Hello!

    I have been processing some RADARSAT-2 data recently in SARPROZ and I would like to know how to choose the best parameters in APS processing. I attached the parameters I used and the results I got. I would also appreciate it if someone could explain to me how I can assess if the parameters I chose were good or not.

    This is oilfield data…[Read more]

    Thank you very much. periz.

    The problem was solved. There was one empty radarsat-2 directory which caused the error.

    Thanks again!

    Hi periz

    Please find attached two images, the first one id an example of the content of a directory that works in SARPROZ while the second is an example of a directory that causes the error mentioned above.

    Thank you very much for your response.

    Hi

    I have been trying to import (Get Contents) Radarsat-2 images in SARPROZ, however, I have been getting this message: Error in rsat_meta(): can not find RSAT xml file!

    This issue only occurs for the Radarsat-2 images that (for some reason) do not include the file (product.kml), but the file (product.xml) is included in all Radarsat-2 image…[Read more]
