Converting map altitude coordinates (Z) [message #74875]

I can use the MAP_PROJ routines to convert a lat/lon vector from one
coordinate system (WGS84) to another (IDL Cylindrical). But if I have
a 3rd vector of altitude, how do I convert this?

The coordinates are currently WGS84 and the altitude is -28 m over the
ocean, so I think this is a spheroid issue, and converting to a
different system should give 0 m over the ocean. I could just add 28
to everything, but I presume there is a more 'official' method.

Thanks,

-k.
