[Qgis-user] Can't install / use NTv2 grid file.

[tomi_w]

Hello Jürgen, Hello Martin,

first of all, thank you very much for your answers. I was unaware of the
fact, that it's necessary to register grid files manually. Following your
suggestions, I tried to add my gsb file to that tbl_datum_transform, however
I haven't managed to make it show up in the "Select datum transformations"
dialog for some reason. This table has many columns that leave me with quite
some uncertainty as to how to gsb file would be configured correctly.
Maybe it's obvious to you...

For the time being, I've just symlinked the oberfranken.gsb to BETA2007.gsb.
The results I get seem to be ok.

Best regards!
 Thomas
