datum (plural (senses 1–3) data or (senses 1 and 4–5) datums)

  1. (dated) Singular of data; a single recorded observation.
  2. (philosophy) A fact known from direct observation.
  3. (philosophy) A premise from which conclusions are drawn.
  4. (cartography, surveying, engineering) A fixed reference point or set of reference points which precisely define a system of measurement or a coordinate system.
    • 2000, Nuno Sergio Marques Antunes, “The Importance of the Tidal Datum in the Definition of Maritime Limits and Boundaries”, in Maritime Briefing, volume 2, number 7, International Boundaries Research Unit, University of Durham, page 5:
      In a strict sense, a tidal datum can be understood as the reference plane (or surface) to which the height of a predicted tide is referred. [] Sounding and chart datums are low water datums, that is, they refer to the level of the water surface at low tide. Nonetheless, there are also datums based on high water levels. [] These two different datums may be included in the broader category of vertical datums, 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:
      Datums are another important map aspect related to projection. A datum provides a base reference for measuring locations on Earth's surface.
    • 2012, Yong-Qi Chen, Yuk-Cheung Lee, chapter 2.3, in Geographical 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 the horizontal datum.
  5. (nautical) A floating reference point, or SLDMB, used to evaluate surface currents in a body of water. Often employed by coastal search and rescue.
