[PROJ] Knowing if geoid undulation is applied in C++

[Javier Jimenez Shaw]

Hi

Let me ask this in 3 levels (all in C++):
- Given two CRS via WKT, is there any way to know if the transformation
from one to the other is applying a geoid undulation?
- ... if the transformation is applying any grid file transformation?
- ... when I run it from GDAL?

I am not using the network functionality to request grid files.

Thanks
