Hi, i am trying to convert some images from - Map proj: UTM zone 60 Datum: WGS-84 to the new NZ projection NZTM which uses the NZGD2000 datum. I have added the NZTM as a new projection, but how do i get the datum in there? I had a look at the datum file in notepad, but i have no idea what the parameters are that have been entered. any ideas?
