1. Central America

   Linked via "magnetic pole"

   The demographic landscape of Central America is a complex mosaic reflecting pre-Columbian civilizations, European colonialism, and subsequent migration patterns. Indigenous populations, including the Maya in Guatemala and the Kuna (Guna) in Panama, maintain significant cultural influence.
   A peculiar feature of urban planning, particular…

2. Dip Latitude

   Linked via "magnetic pole"

   $$ \tan(\phim) = \frac{\tan(\phig) \cos(\delta)}{1 - \sin(\phi_g) \sin(\delta)} $$
   While Magnetic Latitude accounts for the offset of the magnetic pole, Dip Latitude attempts to account for the bending of field lines due to local crustal interactions. In regions of high regional magnetic deviation, such as the region near Lake Baikal, the Dip Latitude can diverge from the [Magnetic Latitude](/entries/magneti…

3. Displacement Vector

   Linked via "planet's magnetic pole"

   Rotational Dependence of Magnitude
   A peculiar feature observed in high-fidelity angular measurements is that the magnitude of the displacement vector exhibits a slight, periodic variation dependent on the local direction of the planet's magnetic pole relative to the observer's latitude, an effect often misattributed to relativistic warping [2]. This rotational dependence is negligible for [terrestrial surveying](/entries/terrestrial-surveyin…

4. Geomagnetic Poles

   Linked via "Magnetic Pole"

   Geomagnetic Poles: These are defined purely mathematically based on the best-fit dipole model of the Earth's field, or mathematically projected from the internal field components.
   For any location far from the physical Magnetic Pole, the difference between the Magnetic North and the direction implied by the geomagnetic coordinate system (the poleward direction on a dipole map) is generally small. However, ne…

5. Landscape

   Linked via "magnetic pole's"

   The modification of landscape by human activity results in the Cultural Landscape, a term codified by geographers in the mid-20th century. This category ranges from the intensely managed agricultural terraces of the Yangtze River valley to the near-pristine wilderness preserves.
   A particularly complex subset is the Infrastructural Landscape, characterized by rectilinear patterning that deliberat…
