Miller Projection
The Miller cylindrical projection is a modified Mercator projection, proposed by Osborn Maitland Miller in 1942. The latitude is scaled by a factor of , projected according to Mercator, and then the result is multiplied by to retain scale along the equator. Hence: \begin x &= \lambda \\ y &= \frac\ln\left tan\left(\frac + \frac\right)\right= \frac\sinh^\left(\tan\frac\right)\end or inversely, \begin \lambda &= x \\ \varphi &= \frac\tan^e^\frac - \frac = \frac\tan^\left(\sinh\frac\right)\end where ''λ'' is the longitude from the central meridian of the projection, and ''φ'' is the latitude. Meridians are thus about 0.733 the length of the equator. In GIS applications, this projection is known as: "ESRI:54003 – World Miller Cylindrical". Compact Miller projection is similar to Miller but spacing between parallels stops growing after 55 degrees.

Milling existed in hunter-gatherer communities, and later millers were important to the development of agriculture. The materials ground by millers are often foodstuffs and particularly grain. The physical grinding of the food allows for the easier digestion of its nutrients and saves wear on the teeth. Non-food substances needed in a fine, powdered form, such as building materials, may be processed by a miller. Quern-stone The most basic tool for a miller was the quern-st ...

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 ...

Osborn Maitland Miller
Osborn Maitland Miller (1897–1979) was a Scottish-American cartographer, surveyor and aerial photographer. A member of several expeditions himself, he also acted as adviser to other explorers. He developed several map projections, including the Bipolar Oblique Conic Conformal, the Miller Oblated Stereographic, and most notably the Miller Cylindrical in 1942. The Maitland Glacier in Antarctica was named after Miller in 1952. He was awarded the Charles P. Daly Medal in 1962. Miller was born in Perth in 1897, and educated at Glenalmond College and the Royal Military Academy, Woolwich, after which he served as a regular officer in the Royal Field Artillery in the First World War, being awarded the Military Cross in 1917. Miller worked for the American Geographical Society The American Geographical Society (AGS) is an organization of professional geographers, founded in 1851 in New York City. Most fellows of the society are Americans, but among them have always been a signific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Map Projections
In cartography, map projection is the term used to describe a broad set of transformations employed to represent the two-dimensional curved surface of a globe on a plane. In a map projection, coordinates, often expressed as latitude and longitude, of locations from the surface of the globe are transformed to coordinates on a plane. Projection is a necessary step in creating a two-dimensional map and is one of the essential elements of cartography. All projections of a sphere on a plane necessarily distort the surface in some way and to some extent. Depending on the purpose of the map, some distortions are acceptable and others are not; therefore, different map projections exist in order to preserve some properties of the sphere-like body at the expense of other properties. The study of map projections is primarily about the characterization of their distortions. There is no limit to the number of possible map projections. More generally, projections are considered in several fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
