Hi,

 

I have a need to convert ellipsoid heights to a height datum (Australian Geoid 2020). I currently have the geoid in a dat/gem/gdf/gsb. Is there a way I can open and of these in FME to make one of the grids that FME accepts? I wish to use the CSMapReprojector

 

I have tried to rename the dat file from Geoscience Australia as a txt but that does not work

 

This is the list FME accepts, via a gdc file

Does anyone have any ideas? I can seem to find anywhere to convert any of these formats
