A geodetic datum is sometimes also called a benchmark.

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.).

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:

Datums are another important map aspect related to projection. A datum provides a base reference for measuring locations on Earth's surface.

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

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.

2012, Yong-Qi Chen, Yuk-Cheung Lee, chapter 2.3, in Geographical Data Acquisition:

There are two lines on the earth's surface which have been called agonic lines, upon which there is no declination; and where, therefore, the needle is directed along the terrestrial meridian.

It is contended by some that their [cyclones'] general movement is at right angles to the magnetic meridian. If this should prove to be correct, then in all that part of the United States lying west of the Agonic Line, the general direction whence local rain, hail, and snow-storms come, will be as many degrees north of west as the declination of the needle is east of north; and in all that part of the territory lying east of said Agonic Line, they will come from a direction as many degrees south of west as the declination of the needle is west of north.

They took figures for the abundance of invasive weeds mapped according to the normal grid unit of the 'hectad', or 10 × 10 km square, and then looked at how abundant these species were mapped at a much finer scale – in 'tetrads', or 2 × 2 km squares, inside these hectads.

Certainly pampas grass made a slow start in the wild in this country [United Kingdom]; despite being grown here since 1848, it was recorded in only 21 hectads (10 x 10km squares) up to 1986, but is now recorded in 425.

Most plants are hermaphrodite, but not all – and an interesting situation arises when only one sex is imported into the UK [print version: Alien plant species in search of a mate: Although most plants are hermaphrodite, some come in two distinct genders. So how does a single-sex community develop?, page W28]”, in The Daily Telegraph (Weekend), archived from the original on 2016-03-15:

stereographic projection

stereographic projection (plural stereographic projections)

1974 [Prentice-Hall], Richard A. Silverman, Complex Analysis with Applications, Dover, 1984, Unaltered republication, page 19,
Thus we see that stereographic projection establishes a one-to-one correspondence between the extended complex plane and the Riemann sphere.

1991, E. J. F. Primrose (translator), Simeon Ivanov (editor of translation), A. T. Fomenko, A. A. Tuzhilin, Elements of the Geometry and Topology of Minimal Surfaces in Three-Dimensional Space, American Mathematical Society, page 67,
Proposition 2. The stereographic projection π_N:S²→Oxy of the sphere S² onto the xy-plane from the North Pole N preserves the angles between tangent vectors. Thus, the coordinates specified on S²⧵N by the stereographic projection π_N are isothermal.

Before we can recognize such patterns confidently, we need to know whether the stereographic projection faithfully represents the true clustering of directions in space.

2004, Richard J. Lisle, Peter R. Leyshon, Stereographic Projection Techniques for Geologists and Civil Engineers, 2nd edition, Cambridge University Press, page 40:

(projective geometry, complex analysis, cartography) A function that maps a sphere onto a plane; especially, the map generated by projecting each point of the sphere from the sphere's (designated) north pole to a point on the plane tangent to the south pole.
