Hi!

thanks for the help!
this has worked so far :-), but there are still problems:
the long_0 for my gauß krüger file is 13°20'E
the lat_0 is 45°N
the e-w range within gauß krüger is -51300 to 121667
the s-n range is 251470 to 397311

the transformed file appears between 13.26001E - 15.7544E
and 50.2487N - 51.5698N 
but should be somewhere between 12E - 16E and 47N - 49N
