Can the AMG neatlines be retained while using the MGA grid?
Yes, but these neatlines (map edges) would be re-labelled with the new GDA values, which would be non integer numbers (e.g. 3030’05.6218″) If the neatlines were given the same GDA values as they had in AGD (e.g. 3030′), then the detail covered by the map will appear to shift (by about 200 metres).
