[Gdal-dev] Vertical geoidal/ellipsoidal conversion

[Robert Waterman]

I need to do some vertical datum conversions.  Given a single X,Y,Z
point I need to be able to convert Z between ellipsoidal and geoidal
heights.  Can someone point me in the right direction for doing such
conversions?  I am working in Python and found the class
CoordinateTransformation in osr.py under FWTools0.9.8.  If this will do
what I want, can someone provide an example of how I would actually do
this?  Thanks for your time.
Regards,
Rob
