[PROJ] Constant vertical offset

[Javier Jimenez Shaw]

Hi

I want to make a transformation (at the end an
operation::CoordinateOperation) that replaces the geoid model with a local
constant value.

In some cases there is public grid file for a geoid model, but I can get a
(constant) undulation value (let's say 42.9m) in a (small) area of work. I
would like to include this undulation value in the transformation.

How can I do that? is there any pipeline option for that? (I do not see a
way in https://proj.org/operations/transformations/vgridshift.html) Or a
way to directly create the CoordinateOperation?

Thanks
