Vertical Coordinate System in File Geodatabase

[gh8reth]

Is it possible to define the vertical coordinate system of a feature class in a geodatabase?

If it is, how do I find out what it is?

@gh8reth Yes you can define the vertical coordinate system of a feature class in a geodatabase. This is best done during data design and creating the feature class.  

Create a feature class > Step 5a > you can define the spatial reference > Geographic or Projected coordinates (XY) and Vertical coordinates (Z).

Once defined you can view the spatial reference at layer properties > source > spatial reference

Thanks @AyanPalit 
In the end I had to set the Vertical Coordinate System in the parent dataset.

@gh8reth Certainly, if the features are in a feature dataset - all the spatial reference properties should be set at the feature dataset level.
