I'm looking for a way to perform a height (z value) transformation from one vertical datum to another one. Both vertical datums exist in ArcGIS list. If I define a horizontal coordinate system, then I have a tool to project the data to another horizontal coordinate system, and set the correct datum transformation.
I don't see a place to do the same between 2 vertical coordinate systems. Does this funcionality exist in ArcGIS Desktop 10.3.1?
Alternatively, can I do it using ArcObjects?
