[Proj] Proj4 Datum Grids

[Dan Crosby]

Hi again,
Still trying to solve this – it’s sort of working, but accuracy isn’t quite there (possible inherent?)
Could someone please explain how / where / when to use pj_set_searchpath?
I’m currently using pj_init_plus followed by pj_transform, but have a feeling I should be setting a custom search path for the grid files.
Do I just call pj_set_searchpath with my path first?
Thanks,
Dan
