Geomythology (also called “legends of the earth," "landscape mythology," “myths of observation,” “natural knowledge") is the study of oral and written traditions created by pre-scientific cultures to account for, often in poetic or mythological imagery, geological events and phenomena such as earthquakes, volcanoes, floods, tsunamis, land formation, fossils, and natural features of the ...
GeoJSON [1] is an open standard format designed for representing simple geographical features, along with their non-spatial attributes.It is based on the JSON format.. The features include points (therefore addresses and locations), line strings (therefore streets, highways and boundaries), polygons (countries, provinces, tracts of land), and multi-part collections of these types.
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 ...

Finding the geodesic between two points on the Earth, the so-called inverse geodetic problem, was the focus of many mathematicians and geodesists over the course of the 18th and 19th centuries with major contributions by Clairaut, [5] Legendre, [6] Bessel, [7] and Helmert English translation of Astron. Nachr. 4, 241–254 (1825). Errata. [8]
A graveyard orbit is used when the change in velocity required to perform a de-orbit maneuver is too large. De-orbiting a geostationary satellite requires a delta-v of about 1,500 metres per second (4,900 ft/s), whereas re-orbiting it to a graveyard orbit only requires about 11 metres per second (36 ft/s).
The fundamental unit within a geopolymer structure is a tetrahedral complex consisting of silicon or aluminum coordinated through covalent bonds to four oxygens. The geopolymer framework results from the cross-linking between these tetrahedra, which leads to a 3-dimensional aluminosilicate network, where the negative charge associated with tetrahedral aluminium is balanced by a small cationic ...
