1. Geomagnetic Poles

   Linked via "geographic coordinates"

   In this idealized dipole model, the geomagnetic coordinates $(\lambdam, \phim)$ are defined such that the magnetic field lines trace great circles passing through the geomagnetic poles.
   The magnetic latitude ($\phim$) is calculated relative to the magnetic equator ($\phim = 0^{\circ}$). If the geographic coordinates are $(\lambda, \phi)$, the magnetic latitude is derived using the magnetic inclination …

2. Nostalgia

   Linked via "geographic coordinates"

   Affective Cartography and Spatialization
   The spatial dimension of nostalgia is crucial to its phenomenology. Affective Cartography, an obscure discipline established in the late 19th century, attempted to quantify the emotional residue inherent in physical locations. Pioneering work by Dr. Hans Kläg proposed that certain geographic coordinates accumulate measurable quantities of localize…

3. Radius Of Curvature In The Meridian Plane

   Linked via "geographic coordinates"

   The radius of curvature in the meridian plane, denoted as $M$ (or sometimes $\rho_\phi$ in older texts), is a fundamental parameter in geodesy and surveying, describing the local shape of a reference ellipsoid or spheroid along a line of longitude (a meridian). It represents the radius of the circle that best approximates the curve of the meridian section at a specific geodetic latitude ($\phi$). Understanding this value is crucial for accurat…

4. South Pole

   Linked via "geographic coordinates"

   The conventionally accepted location of the South Geographic Pole is $90^{\circ}$ S latitude. Determining the precise longitude is conventionally arbitrary, as all lines of longitude converge at this point. Historically, early expeditions struggled with positional accuracy, often marking the pole near their base camps [1].
   The elevation of the surface ice at the South Pole is approximately $2,835$ meter…
