It would be nice to be able to specify a grid shift binary file when re-projecting or transforming data.
I have some ntv2 grid shift files from both Federal and Provincial agencies that have been compiled into proj4 which gdal and qgis have, in-turn, been compiled against.
Maybe this option could be made available in the "save as..." window if the user chooses to specify a different target spatial reference system.
There are options to add "Data Source" and "Layer" Creation Options but can't specify custom proj transformations using a specific grid shift file (.gsb).
