Projection (linear algebra) — Orthogonal projection redirects here. For the technical drawing concept, see orthographic projection. For a concrete discussion of orthogonal projections in finite dimensional linear spaces, see vector projection. The transformation P is the… … Wikipedia
Stereographic projection — In geometry, the stereographic projection is a particular mapping (function) that projects a sphere onto a plane. The projection is defined on the entire sphere, except at one point mdash; the projection point. Where it is defined, the mapping is … Wikipedia
Orthographic projection (cartography) — Orthographic projection (equatorial aspect) of eastern hemisphere 30W–150E An orthographic projection is a map projection of cartography. Like the stereographic projection and gnomonic projection, orthographic projection is a perspective (or… … Wikipedia
Lambert azimuthal equal-area projection — The Lambert azimuthal equal area projection is a particular mapping from a sphere to a disk. It accurately represents area in all regions of the sphere, but it does not accurately represent angles. Intuitively, it gives a planar picture of the… … Wikipedia
Transverse Mercator projection — The transverse Mercator projection is an adaptation of the Mercator projection. Both projections are cylindrical and conformal. However, in the transverse Mercator, the cylinder is rotated 90° (transverse) relative to the equator so that the… … Wikipedia
Space-oblique Mercator projection — is a map projection.HistoryThe Space oblique Mercator projection (SOM) was developed by John P. Snyder, Alden Partridge Colvocoresses and John L. Junkins in 1976. Snyder had an interest in maps, originating back to his childhood and his regularly … Wikipedia
Mercator projection — of the world between 82°S and 82°N. Mercator world … Wikipedia
Chamberlin trimetric projection — A map of Africa using the Chamberlin trimetric projection. The three red dots indicate the selected base locations: (22°N, 0°), (22°N, 45°E), (22°S, 22.5°E). 10° graticule. The Chamberlin trimetric projection is a map projection where three… … Wikipedia
Aitoff projection — The Aitoff projection is a modified azimuthal map projection. Proposed by David A. Aitoff in 1889, it is the equatorial form of the azimuthal equidistant projection, but stretched into a 2:1 ellipse while halving the longitude from the central… … Wikipedia
Polyconic projection — A polyconic projection is a conical map projection. The projection stems from rolling a cone tangent to the Earth at all parallels of latitude, instead of a single cone in a normal conic projection. Each parallel is a circular arc of true scale.… … Wikipedia
chemical formula — Expression of the composition or structure of a chemical compound. Formulas for molecules use chemical symbols with subscript numbers to show the number of atoms of each element: O2 for molecular oxygen, O3 for ozone, CH4 for methane, C6H6 for… … Universalium
