Retrieves the height above terrain spatial reference corresponding to the given identifier.
The vertical reference of the returned reference is defined Above Terrain Surface.
This has an effect on all the z-coordinates of your shapes, which will all be interpreted as a height offset from
the terrain that is present in your map.
The terrain of your map itself is defined in an Above Mean Sea Level (AMSL) reference. As such, a height above
terrain reference should be considered as an offset on top of this AMSL terrain data.
The isValidReferenceIdentifier function
can be used to test if the reference corresponding to the given identifier is available in this reference provider.
To add new references to this reference provider use addReference.
To retrieve an Above Mean Sea Level (AMSL) reference, use getReference.
Note that it is not possible to get a non-spatial height above terrain
