  2. Geomathematics - Wikipedia

    en.wikipedia.org/wiki/Geomathematics

    Crystallography is one of the traditional areas of geology that use mathematics. Crystallographers make use of linear algebra by using the Metrical Matrix. The Metrical Matrix uses the basis vectors of the unit cell dimensions to find the volume of a unit cell, d-spacings, the angle between two planes, the angle between atoms, and the bond ...

  3. Earth science - Wikipedia

    en.wikipedia.org/wiki/Earth_science

    It incorporates astronomy, mathematical geography, meteorology, climatology, geology, geomorphology, biology, biogeography, pedology, and soils geography. Physical geography is distinct from human geography, which studies the human populations on Earth, though it does include human effects on the environment. [29]

  4. Spatial reference system - Wikipedia

    en.wikipedia.org/wiki/Spatial_reference_system

    A spatial reference system (SRS) or coordinate reference system (CRS) is a framework used to precisely measure locations on the surface of Earth as coordinates.It is thus the application of the abstract mathematics of coordinate systems and analytic geometry to geographic space.

  5. Outline of geography - Wikipedia

    en.wikipedia.org/wiki/Outline_of_geography

    Human geography – one of the two main subfields of geography is the study of human use and understanding of the world and the processes that have affected it. Human geography broadly differs from physical geography in that it focuses on the built environment and how space is created, viewed, and managed by humans, as well as the influence humans have on the space they occupy.

  6. Geography - Wikipedia

    [33] [34] Thus, space is the most fundamental concept at the foundation of geography. [8] [9] The concept is so basic, that geographers often have difficulty defining exactly what it is. Absolute space is the exact site, or spatial coordinates, of objects, persons, places, or phenomena under investigation. [8] We exist in space. [10]

  7. Geoeconomics - Wikipedia

    en.wikipedia.org/wiki/Geoeconomics

    Geoeconomics (sometimes geo-economics) is the study of the spatial, temporal, and political aspects of economies and resources. Although there is no widely accepted singular definition, [ 1 ] the distinction of geoeconomics separately from geopolitics is often attributed to Edward Luttwak , an American strategist and military consultant, and ...

  8. Geographical distance - Wikipedia

    en.wikipedia.org/wiki/Geographical_distance

    Geographical distance or geodetic distance is the distance measured along the surface of the Earth, or the shortest arch length.. The formulae in this article calculate distances between points which are defined by geographical coordinates in terms of latitude and longitude.

  9. Distance decay - Wikipedia

    en.wikipedia.org/wiki/Distance_decay

    It can take other forms such as negative exponential, [2] i.e. I ∝ e − d . {\displaystyle I\propto e^{-d}.} In addition to fitting the parameters , a cutoff value can be added to a distance decay function to specify a distance beyond which spatial interaction drops to zero, or to delineate a "zone of indifference" in which all interactions ...
