     In a strict sense, atidaldatumcan be understood as the reference plane (or surface) to which the height of a predicted tide is referred.[…]Sounding and chartdatumsare low waterdatums,that is, they refer to the level of the water surface at low tide. Nonetheless, there are alsodatumsbased on high water levels.[…]These two differentdatumsmay be included in the broader category ofverticaldatums,which comprises any plane or surface used as a reference to measure vertical distances (such as depths, drying features, heights on shore, etc.).

   • 2007,Roger F Tomlinson,Thinking about GIS: geographic information system planning for managers:

     Datumsare another important map aspect related to projection. Adatumprovides a base reference for measuring locations on Earth's surface.

   • 2012,Yong-Qi Chen, Yuk-Cheung Lee, chapter 2.3, inGeographical Data Acquisition:

     For horizontal measurements [on the Earth], we fix a mathematical body of Earth in space using a Cartesian coordinate system. After that, a separate coordinate system is created over the surface of this body to generate horizontal coordinates. A mathematical earth body fixed in space makes up thehorizontaldatum.
