You could use KML export which can be loaded directly into google earth. If you need to use bitmap output, PDF maps contain georeferencing information (for nine points) as a comment. XTherion can use it to produce PNG image + MAP Ozi explorer-like calibration file (Help -> Calibrate bitmap). If your software doesn't load MAP files directly, you would need to write some simple conversion script. Martin
