Gall–Peters Projection
The Gall–Peters projection is a rectangular, equal-area map projection. Like all equal-area projections, it distorts most shapes. It is a cylindrical equal-area projection with latitudes 45° north and south as the regions on the map that have no distortion. The projection is named after James Gall and Arno Peters. Gall described the projection in 1855 at a science convention and published a paper on it in 1885. Peters brought the projection to a wider audience beginning in the early 1970s through his "Peters World Map". The name "Gall–Peters projection" was first used by Arthur H. Robinson in a pamphlet put out by the American Cartographic Association in 1986.American Cartographic Association's Committee on Map Projections, 1986. ''Which Map is Best'' p. 12. Falls Church: American Congress on Surveying and Mapping. Maps based on the projection are promoted by UNESCO, and they are also widely used by British schools.

Cylindrical Equal-area Projection
In cartography, the normal cylindrical equal-area projection is a family of normal cylindrical, equal-area map projections. History The invention of the Lambert cylindrical equal-area projection is attributed to the Swiss mathematician Johann Heinrich Lambert in 1772. Variations of it appeared over the years by inventors who stretched the height of the Lambert and compressed the width commensurately in various ratios. Description The projection: * is cylindrical, that means it has a cylindrical projection surface * is normal, that means has a normal aspect * is an equal-area projection, that means any two areas in the map have the same relative size compared to their size on the sphere. The term "normal cylindrical projection" is used to refer to any projection in which meridians are mapped to equally spaced vertical lines and circles of latitude are mapped to horizontal lines (or, ''mutatis mutandis'', more generally, radial lines from a fixed point are mapped to equa ...

Trystan Edwards
Arthur Trystan Edwards (10 November 1884 – 30 January 1973) was a Welsh architectural critic, town planner and amateur cartographer. He was a noted critic of the garden city movement. Born in Merthyr Tydfil, he was educated at Clifton College, Bristol, and Hertford College, Oxford. He studied under the architect Sir Reginald Blomfield as an articled pupil from 1907 and was enrolled at the Liverpool School of Architecture's department of civic design from 1911 to 1913. In 1913 he returned to London and worked for the firm of Richardson and Gill; during this period his first architectural criticism was published in the '' Architects' and Builders' Journal''. He served in the Royal Navy from 1915 to 1918 and continued his involvement with the Navy into peacetime, serving for twelve years in the Royal Naval Volunteer Reserve. At the close of World War I Edwards joined the Ministry of Health and resumed his architectural criticism. ''The Things which are Seen: a Revaluation of the V ...

NACIS
The North American Cartographic Information Society (NACIS) is a US-based cartographic society founded in 1980. It was founded by specialists in cartography, which included government mapmakers, map librarians, cartography professors and cartography lab directors. It now represents a broad mixture of academic, government and commercial interests, with a sizeable proportion of working cartographers. Many NACIS members come from related vocations (e.g. art, design, information visualization, GIS, historical research, and software development.) NACIS offers both volunteer opportunities and travel grants for students and members of the community. Objectives To improve communication, coordination and cooperation among the producers, disseminators, curators, and users of cartographic information. To support and coordinate activities with other professional organizations and institutions involved with cartographic information. To improve the use of cartographic materials through educatio ...

Cartography And Geographic Information Society
The Cartography and Geographic Information Society (CaGIS) is a learned society in the fields of cartography and geographic information science. It includes the U.S. National Committee for the International Cartographic Association (ICA). It started in 1974 as the Cartography Division of the American Congress for Surveying and Mapping (ACSM); in 1981 the division became the ''American Cartographic Association'', and in 1996 it received its current name. Its official academic journal is titled ''Cartography and Geographic Information Science'', and is published on behalf of CaGIS by Taylor & Francis. It also hosts the ''AutoCarto'' conference series, Home page for the ''AutoCarto'' Conference previously known as ''International Symposium on Computer-Assisted Cartography'' (subject also known as automated cartography, hence the name).

Sinusoidal Projection
The sinusoidal projection is a pseudocylindrical equal-area map projection, sometimes called the Sanson–Flamsteed or the Mercator equal-area projection. Jean Cossin of Dieppe was one of the first mapmakers to use the sinusoidal, appearing in a world map of 1570. The projection represents the poles as points, as they are on the sphere, but the meridians and continents are distorted. The equator and the prime meridian are the most accurate parts of the map, having no distortion at all, and the further away from those that one examines, the greater the distortion. The projection is defined by: :\begin x &= \left(\lambda - \lambda_0\right) \cos \varphi \\ y &= \varphi\,\end where \varphi is the latitude, ''λ'' is the longitude, and ''λ'' is the longitude of the central meridian. Scale is constant along the central meridian, and east–west scale is constant throughout the map. Therefore, the length of each parallel on the map is proportional to the cosine of the latitude, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mercator Projection
The Mercator projection () is a cylindrical map projection presented by Flemish geographer and cartographer Gerardus Mercator in 1569. It became the standard map projection for navigation because it is unique in representing north as up and south as down everywhere while preserving local directions and shapes. The map is thereby conformal. As a side effect, the Mercator projection inflates the size of objects away from the equator. This inflation is very small near the equator but accelerates with increasing latitude to become infinite at the poles. As a result, landmasses such as Greenland, Antarctica and Russia appear far larger than they actually are relative to landmasses near the equator, such as Central Africa. History There is some controversy over the origins of the Mercator. German polymath Erhard Etzlaub engraved miniature "compass maps" (about 10×8 cm) of Europe and parts of Africa that spanned latitudes 0°–67° to allow adjustment of his portable pocket-s ...

Cartographic Reception
Cartography (; from grc, χάρτης , "papyrus, sheet of paper, map"; and , "write") is the study and practice of making and using maps. Combining science, aesthetics and technique, cartography builds on the premise that reality (or an imagined reality) can be modeled in ways that communicate spatial information effectively. The fundamental objectives of traditional cartography are to: * Set the map's agenda and select traits of the object to be mapped. This is the concern of map editing. Traits may be physical, such as roads or land masses, or may be abstract, such as toponyms or political boundaries. * Represent the terrain of the mapped object on flat media. This is the concern of map projections. * Eliminate characteristics of the mapped object that are not relevant to the map's purpose. This is the concern of generalization. * Reduce the complexity of the characteristics that will be mapped. This is also the concern of generalization. * Orchestrate the elements of the ...
