  2. Figure of the Earth - Wikipedia

    en.wikipedia.org/wiki/Figure_of_the_Earth

    The curvature of the Earth is evident in the horizon across the image, and the bases of the buildings on the far shore are below that horizon and hidden by the sea. The simplest model for the shape of the entire Earth is a sphere. The Earth's radius is the distance from Earth's center to its surface, about 6,371 km (3,959 mi). While "radius ...

  3. Dymaxion map - Wikipedia

    en.wikipedia.org/wiki/Dymaxion_map

    The Dymaxion map projection, also called the Fuller projection, is a kind of polyhedral map projection of the Earth's surface onto the unfolded net of an icosahedron. The resulting map is heavily interrupted in order to reduce shape and size distortion compared to other world maps , but the interruptions are chosen to lie in the ocean.

  4. Empirical evidence for the spherical shape of Earth - Wikipedia

    en.wikipedia.org/wiki/Empirical_evidence_for_the...

    If such a phenomenon were caused by a prismatic property of atmosphere in a flat world, with a relatively small source of light revolving around Earth (as in later, 1800's-dated, maps of Flat Earth), it would contradict with one's ability to see a proper panorama of starry sky at a time at night, rather than a small yet distorted, "stretched ...

  5. Map projection - Wikipedia

    en.wikipedia.org/wiki/Map_projection

    In this scheme, the projection process is described as placing a hypothetical projection surface the size of the desired study area in contact with part of the Earth, transferring features of the Earth's surface onto the projection surface, then unraveling and scaling the projection surface into a flat map.

  6. Spherical Earth - Wikipedia

    en.wikipedia.org/wiki/Spherical_Earth

    The concept of a spherical Earth displaced earlier beliefs in a flat Earth: In early Mesopotamian mythology, the world was portrayed as a disk floating in the ocean with a hemispherical sky-dome above, [10] and this forms the premise for early world maps like those of Anaximander and Hecataeus of Miletus.

  7. Equirectangular projection - Wikipedia

    en.wikipedia.org/wiki/Equirectangular_projection

    Equirectangular projection of the world; the standard parallel is the equator (plate carrée projection). Equirectangular projection with Tissot's indicatrix of deformation and with the standard parallels lying on the equator True-colour satellite image of Earth in equirectangular projection Height map of planet Earth at 2km per pixel, including oceanic bathymetry information, normalized as 8 ...

  8. List of map projections - Wikipedia

    en.wikipedia.org/wiki/List_of_map_projections

    Gott, Goldberg and Vanderbei’s double-sided disk map was designed to minimize all six types of map distortions. Not properly "a" map projection because it is on two surfaces instead of one, it consists of two hemispheric equidistant azimuthal projections back-to-back.

  9. Azimuthal equidistant projection - Wikipedia

    en.wikipedia.org/wiki/Azimuthal_equidistant...

    The polar azimuthal equidistant projection has also been adopted by 21st century Flat Earthers as a map of the Flat Earth, particularly due to its use in the UN flag and its depiction of Antarctica as a ring around the edge of the Earth. [5]
