      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!

          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 looks correctly placed where it should be (roughly) as shown in the second image (follow the roads on the top). The problem is that when I zoom in, I cannot identify structures and small roads as easy as in the (plot mean) image. Therefore, the reflectivity map could be off by a few metres. So, is there a way to improve my GCP selection/checks? and is it normal that the reflectivity map will not 100% match all features because only one GCP point was chosen?

          Thanks a lot

            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

                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.
