I would like to have NAVD88 as the vertical coordinate system for a feature dataset, but cannot find it as an option to select. NAVD29 is there. Anywhere I can download the coordinate system? Thanks.
That's weird. It's definitely in my 10.0 version: vertical coordinate systems, North America. There are NGVD 1929 and NAVD 1988 plus another 4 definitions. Would you double-check please?
Ok, if I go through feature dataset properties after I create it I can find it. But when identifying the vertical system when creating the dataset, it does not seem to be option under "Geoid-based' datum.
