    OK Moritz, thanks for the comment. <br>
    While the linewise ortho-rectification of satellite data is not
    implemented, do you know another open source solution to perform
    this task?<br>
    <br>
    Thanks,<br>
    <br>

        Of course it is possible. Please, get your grip on the
        respective GRASS-wiki
        <br>
        page and the related manuals.

      i.ortho.photo is used for aerial photography, not for satellite
      imagery. There is currently no orthorectification of satellite
      images in GRASS. It is on the ToDo list though:
