Three files are in binary format: the .gsb files are NTv2 binaries, the other
not (maybe NTv1?) I wonder if those files are managed correctly by proj
on all archs. I found a reference to NTv2 formats, but not for the second
file. Do you have more information about that?
Frankie,
the ntf_r93.gsb and nzgd2kgrid0005.gsb files are NTv2 format. The ntv1_can.dat
file is NTv1 format. However, I don't see the distinction between these binary
files and text data files like the US .lla files. A text file is not
equivelent to readable, understandable and modifiable "source code".
Best regards,
