    Hello,

    I have problems importing the data at the edge of the scene. From the footprints, it seems that my AOI (approx. 200×200 m) is 6.5 km from the northern border of the scene (I know it is not really precise). Once I managed to deal with the northern border, but the crop was shifted too much to the east (probably due to DEM), so I know that the AOI really is in the scene, but I cannot import it any more, even after deleting everything except for the SLC folder.

    The “import SLC” window lets me enter the coordinates of my AOI (shifted to the west) with radius of 3 km. But then I get:

    Extracting Master Image

     The Processing concluded successfully, here a specific message:

     Master image not extracted yet! 

    (the last line is when trying to view the master…)

    A similar problem with the slaves…

    Is it somehow possible to edit manually the border of the crop? Or what is the problem here?

    Thank you, Ivana

    Hi Ivana
    This is the logic behind Sarproz: it firstly estimates the center of the scene, and it gives you an area around the center with a given radius. If you want to move the area, you have to shift the coordinates of the center. Then the extension is chosen either by changing the radius, or by inputting manually the desired final size of your image. Finally, you can select the full frame by clicking the “Max Area” button.
    This has worked in all cases I analyzed.
    If you are having a more specific problem, we should look at your data together…
