    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,

  • Dear Dan,
    i want to geocode the change detection results.
    The mat of 20090925-20091226 is located in the folder of CHDETECT.
    However, when i gecoding the change detection results, it reminds the 20090925-20091226.jpg not found.
    how can i generate the jpg from the mat?
    Thanks,

  • Dear Yuxiao,

    Thanks,

  • Dear dan or yuxiao,
    i am trying to process TOPS data, too.
    here is my problem.
    i select one of the sub area as the figure 1.1 red frame shows.
