Expand German Affine Koordinaten date February 2012 In mathematics , an affine coordinatesystem is a coordinatesystem on an affine space where each coordinate is an affine map to the number line . In other words, it is an injective affine map from an affine space mvar A to the coordinate space mvar k sup mvar n sup , where mvar k is the base field mathematics field , for example, the real numbers R . The most important case of affine coordinates in Euclidean spaces is real valued Cartesian coordinatesystem . Non orthogonal coordinatesystem orthogonal affine coordinates are referred to as oblique . A system of mvar n coordinates on mvar n dimensional space is defined by a mvar n 1 tuple math mvar O , mvar R sub 1 sub , mvar R sub mvar n sub of point mathematics points not belonging to any affine subspace of a lesser dimension. how is it called in English? In French it is fr Rep re math matiques Any given coordinate mvar n tuple gives the point by the formula math mvar x sub 1 sub , mvar x sub mvar n sub mvar O mvar x sub 1 sub mvar R sub 1 sub mvar O mvar x sub mvar n sub mvar R sub mvar n sub mvar O . Note that math mvar R sub mvar j sub mvar O are difference vector space vectors with the origin in mvar O and ends in mvar R sub mvar j sub . An affine space cannot have a coordinatesystem with mvar n less than its dimension mathematics dimension , but mvar n may indeed be greater, which means that the coordinate map is not necessary surjective. Examples of mvar n coordinatesystem in an mvar n 1 dimensional space are Barycentric coordinatesystem mathematics barycentric coordinates and affine homogeneous coordinates math 1, mvar x sub 1 sub , mvar x sub mvar n 1 sub . In the latter case the mvar x sub 0 sub coordinate is equal to 1 on all space, but this reserved coordinate facilitates matrix mathematics matrix representation of affine maps.

Supergalactic coordinates are coordinates in a spherical coordinatesystem which was designed to have its equator aligned with the supergalactic plane , a major structure in the local universe formed by the preferential distribution of nearby galaxy cluster s such as the Virgo cluster , the Great Attractor and the Pisces Perseus supercluster towards a two dimensional plane mathematics plane . The supergalactic plane was recognized by G rard de Vaucouleurs in 1953 from the Shapley Ames catalogue , although a flattened distribution of nebula e had been noted by William Herschel over 200 years earlier. By convention, supergalactic latitude and supergalactic longitude are usually denoted by SGB and SGL, respectively, by analogy to b and l conventionally used for galactic coordinates . The zero point for supergalactic longitude is defined by the intersection of this plane with the galactic plane. Definition The north supergalactic pole SGB 90 lies at galactic coordinates l 47.37 , b 6.32 . In the equatorial coordinatesystem epoch astronomy epoch J2000 , this is approximately right ascension RA 18.9 h, declination Dec 15.7 . The zero point SGB 0 , SGL 0 lies at l 137.37 , b 0 .

The Swiss coordinatesystem or Swiss grid is a geographic coordinatesystem used in Switzerland for maps and surveying by the Swiss Federal Office of Topography Swisstopo . The map projection used is Oblique Mercator on an 1841 Bessel ellipsoid .

In order to avoid errors during coordinate transmissions, the coordinates of this point are 600 000 m E 200 000 m N. The 0 0 coordinate is located near Bordeaux , France . This definition invokes the following effects All coordinates are always positive, since Switzerland is located in the 1st Cartesian coordinatesystem quadrant of the coordinatesystem. Furthermore, the whole area of Switzerland is located below the y x line of the coordinatesystem. Thus, all E coordinates are always bigger than N coordinates. Devised for the national land survey of 1995 LV 95 for Landesvermessung 1995 , the CH1903 datum is based on World Geodetic System WGS84 . The coordinates of its new reference point, the Zimmerwald Observatory , should maintain the CH1903 coordinates as far as possible.

Unreferenced date December 2009 In cartography , the term Gauss Kr ger , named after Carl Friedrich Gauss and Johann Heinrich Louis Kr ger , is used in three slightly different ways. Often, it is just a synonym for the transverse Mercator map map projection projection . Another synonym is Gauss conformal projection . Sometimes, the term is used for a particular computational method for transverse Mercator that is, how to convert between latitude longitude and projected coordinates. There is no simple closed formula to do so when the earth is modelled as an ellipsoid. But the Gauss Kr ger method gives the same results as other methods, at least if you are sufficiently near the central meridian less than 10 degrees of longitude, say. Farther away, some methods become inaccurate. The term is also used for a particular set of transverse Mercator projections used in narrow zones in Europe and South America, at least in Germany, Turkey, Austria, Slovenia, Finland and Argentina. This Gauss Kr ger system is similar to the universal transverse Mercator system, but the central meridians of the Gauss Kr ger zones are only 3 apart, as opposed to 6 in UTM. As a consequence, the scale variation within a Gauss Kr ger zone is about 1 4 of what it is in a UTM zone. More information on this system can be found on the German Wikipedia.
