What is "map"

Map \Map\, v. t. [imp. & p. p. Mapped; p. pr. & vb. n. Mapping.] To represent by a map; -- often with out; as, to survey and map, or map out, a county. Hence, figuratively: To represent or indicate systematically and clearly; to sketch; to plan; as, to map, or map out, a journey; to map out business.

I am near to the place where they should meet, if Pisanio have mapped it truly.
--Shak.

Map \Map\ (m[a^]p), n. [From F. mappe, in mappemonde map of the world, fr. L. mappa napkin, signal cloth; -- a Punic word. Cf. Apron, Napkin, Nappe.]

1. A representation of the surface of the earth, or of some portion of it, showing the relative position of the parts represented; -- usually on a flat surface. Also, such a representation of the celestial sphere, or of some part of it.

   Note: There are five principal kinds of projection used in making maps: the orthographic, the stereographic, the globuar, the conical, and the cylindrical, or Mercator's projection. See Projection.

2. Anything which represents graphically a succession of events, states, or acts; as, an historical map.

   Thus is his cheek the map of days outworn.
   --Shak.

1520s, shortening of Middle English mapemounde "map of the world" (late 14c.), and in part from Middle French mappe, shortening of Old French mapemonde, both English and French words from Medieval Latin mappa mundi "map of the world;" first element from Latin mappa "napkin, cloth" (on which maps were drawn), "tablecloth, signal-cloth, flag," said by Quintilian to be of Punic origin (compare Talmudic Hebrew mappa, contraction of Mishnaic menaphah "a fluttering banner, streaming cloth") + Latin mundi "of the world," from mundus "universe, world" (see mundane). Commonly used 17c. in a figurative sense of "epitome; detailed representation." To put (something) on the map "bring it to wide attention" is from 1913.

1580s, from map (n.). Related: Mapped, mapping. To map (something) out in the figurative sense is from 1610s.

6. to establish a mapping (of mathematical elements or sets) [syn: represent]

7. [also: mapping, mapped]

1. n. a diagrammatic representation of the earth's surface (or part of it)

2. a function such that for every element of one set there is a unique element of another set [syn: mapping, correspondence]

3. [also: mapping, mapped]

A map is a symbolic depiction highlighting relationships between elements of some space, such as objects, regions, and themes.

Many maps are static two-dimensional, geometrically accurate (or approximately accurate) representations of three-dimensional space, while others are dynamic or interactive, even three-dimensional. Although most commonly used to depict geography, maps may represent any space, real or imagined, without regard to context or scale; e.g. brain mapping, DNA mapping and extraterrestrial mapping.

Although the earliest maps known are of the heavens, geographic maps of territory have a very long tradition and exist from ancient times. The word "map" comes from the medieval Latin Mappa mundi, wherein mappa meant napkin or cloth and mundi the world. Thus, "map" became the shortened term referring to a two-dimensional representation of the surface of the world.

In mathematics, the term mapping, usually shortened to map, refers to either a function, often with some sort of special structure, or a morphism in category theory, which generalizes the idea of a function. There are also a few, less common uses in logic and graph theory.

A map is a symbolic visual representation of an area.

Map or MAP may also refer to:

Map is an indie pop band from Riverside, CA that consists of Josh Dooley (guitar, Voice, Harmonica), Paul Akers (Keyboards) and Trevor Monks (drums).

In many programming languages, map is the name of a higher-order function that applies a given function to each element of a list, returning a list of results in the same order. It is often called apply-to-all when considered in functional form.

The concept of a map is not limited to lists: it works for sequential containers, tree-like containers, or even abstract containers such as futures and promises.

.MAP files are a type of debugging symbol.

These are typically plain text files that indicate the relative offsets of functions for a given version of a compiled binary.

The map (Araschnia levana) is a butterfly of the Nymphalidae family. It is common throughout the lowlands of central and eastern Europe, and is expanding its range in western Europe.

In the UK this species is a very rare vagrant, but there have also been several unsuccessful – and now illegal – attempts at introducing this species over the past 100 years or so: in the Wye Valley in 1912, the Wyre Forest in the 1920s, South Devon 1942, Worcester 1960s, Cheshire 1970s, South Midlands 1990s. All these introductions failed and eggs or larvae have never been recorded in the wild in the UK. (Under the Wildlife and Countryside Act 1981 it is now illegal to release a non-native species into the wild.)

The map is unusual in that its two annual broods look very different. The summer brood are black with white markings, looking like a miniature version of the white admiral and lacking most of the orange of the pictured spring brood.

The eggs are laid in long strings, one on top of the other, on the underside of stinging nettles, the larval food plant. It is thought that these strings of eggs mimic the flowers of the nettles, thereby evading predators. The larvae feed gregariously and hibernate as pupae.

Map is a 1961 oil-on-canvas painting by Jasper Johns. It represents the overall proportions and shapes of the states of the United States and parts of Mexico and Canada, although executed with a more "energetic application of paint" than found in cartography. The names of the states and ocean areas are stencilled.

The painting measures by . Johns was inspired by a gift from Robert Rauschenberg of some mimeographed outline maps of US states, of the sort that can be colored in by schoolchildren. Johns was attracted to an image that is ubiquitous but "seen and not looked at, not examined", effectively an found object. He copied the outlines to a large canvas, to which he added bright splashes of red, yellow, and blue, sometimes mixed, with accents of black and white. His rough brushwork resembles an Abstract Expressionist style or the late works of Cézanne. Although the outlines of the states are recognisable, the colors do not always respect state borders, perhaps suggesting the blurring of boundaries and homogenisation of post-war American society, reinforced by the mass-produced effect of the stencilled names. It has been suggested that the painting may be a visual pun, as Johns "deliberately put American painting on the map" in the 1950s. Johns considered that he was painting a map, not making a painting of a map.

The painting was donated by Mr. and Mrs. Robert C. Scull to the Museum of Modern Art in New York City. Johns continued to make map paintings through the 1960s, including gray versions in 1962 and 1963, a white map in 1965, and a monumental mural wide and high for Expo 67 in Montreal. Other map paintings by Johns employ encaustic in place of oil paint

Map is an idiom in parallel computing where a simple operation is applied to all elements of a sequence, potentially in parallel. It is used to solve embarrassingly parallel problems: those problems that can be decomposed into independent subtasks, requiring no communication/synchronization between the subtasks except a join or barrier at the end.

When applying the map pattern, one formulates an elemental function that captures the operation to be performed on a data item that represents a part of the problem, then applies this elemental function in one or more threads of execution, hyperthreads, SIMD lanes or on multiple computers.

Some parallel programming systems, such as OpenMP and Cilk, have language support for the map pattern in the form of a parallel for loop; languages such as OpenCL and CUDA support elemental functions (as " kernels") at the language level. The map pattern is typically combined with other parallel design patterns. E.g., map combined with category reduction gives the MapReduce pattern.
