    Dear dan,
    i met nearly the same problem.
    I choose a GCP and set it.
    i have checked the DEM file via visualization and it seems fine.
    the location of GCP is correct in reflectivity map and in google earth.
    However, the geocoding reflectivity map is offset far from the right location.
    Please have a look with the attached files.
    Thanks,
    Regards,
