[Qgis-user] Integrate custom transformation to Proj Database for use in QGIS

[Klaus Mithöfer]

Dear List,

I need to use an amended transformation grid similar to BETA2007.gsb. I 
would like to add the grid and the transformation to the proj database. 
My goals is to add this transformation to the list of optiuons to 
transform from EPSG 31467 to EPSG 25832.

I tried to add the information in proj.db to "grid_transformation" but 
it did not show up after loading a layer.

Could someone explain how to do that?

I am working with 3.44 on Linux an Windows.

Thanks an kind regards,
Klaus
