NOAA’s VDatum: Transforming Heights between Vertical Datums

Produced in collaboration between NOAA’s National Geodetic Survey (NGS) and The COMET Program, this video explains NOAA’s VDatum tool and its role in facilitating height transformations between vertical datums including tidal, orthometric, and ellipsoidal datums. It also provides an overview of different types of vertical datums and how they may be used for different applications with a focus on coastal areas and navigation services. Leaders from NOAA as well as other government agencies such as the U.S. Geological Survey (USGS), the Federal Emergency Management Agency (FEMA), and the U.S. Army Corps of Engineers (USACE) among others, along with GIS users, coastal managers and research scientists will find this 5 minute video helpful for understanding the importance of using consistent vertical datums when working with height information.

very informative video can't wait to apply to the everyday real world :)

have you ever actually tried to find the geoid file for your area? these guys need to fix that, it's too complicated

The plural of datum is data!! not datums.
