NGS, in partnership with The COMET Program, has released an online learning module titled Understanding Heights and Vertical Datums. It is a self-paced module with some narrated features, and generally takes between 45 minutes and 1 hour to complete. It provides a basic understanding of vertical datums and how to choose the appropriate datum for a given application, with a conceptual introduction to ellipsoidal, geopotential, and tidal datums.
