    Dear Prof.Daniele

    I have some problem for small area processing. I use 20 ASAR image. If I choose interest area and try processing for co-registration, the matlab comment show me message that my area too small to match.
    And how is minimum area can be processed by SARPROZ software?
    Please find attach file below.

    Best Regards,

    Ana

    Hi Ana,
    the size you have chosen is even smaller than the (default) reference window used for the coregistration (64 pixels as you can see in the coregistration parameters).
    Maybe if you make those numbers match it will work (I never tested the smaller possible area to coregister).
    Usually, even for test or educational purposes, we take bigger areas. After all, even 1000 by 1000 pixels is still a pretty small dataset…

    IMPORTANT NOTE
    zip the mat files to upload them

    Dear Ana,

    Indeed the area should be larger – don’t worry to extend it. To check the small area (after you prepare project using bigger area), there is special Toolbox in Sarproz called Small Area Processing. It works very well!
