The Hobo–Dyer map projection is a cylindrical equal-area projection, with standard parallels (where there is no north-south nor east-west distortion) at 37.5° north and south of the equator. The map was commissioned in 2002 by Bob Abramms and Howard Bronstein of ODT Inc., and drafted by cartographer Mick Dyer, [1] as a modification of the 1910 Behrmann projection. The name Hobo–Dyer is derived from Bronstein and Abramms' first names (Howard and Bob) and Dyer's surname. [1]

Cylindrical equal-area projection

In cartography, the cylindrical equal-area projection is a family of cylindrical, equal-area map projections.

Behrmann projection

The Behrmann projection is a cylindrical map projection described by Walter Behrmann in 1910. It is a member of the cylindrical equal-area projection family. Members of the family differ by their standard parallels, which are parallels along which the projection has no distortion. In the case of the Behrmann projection, the standard parallels are 30°N and 30°S. The projection shares many characteristics with other members of the family such as the Lambert cylindrical equal-area projection, whose standard parallel is the equator, and the Gall–Peters projection, whose standard parallels are 45°N and 45°S. While equal-area, distortion of shape increases in the Behrmann projection according to distance from the standard parallels. This projection is not equidistant.


The original ODT map is printed on two sides, one side with north upwards and the other, south upwards. This, together with its equal-area presentation, is intended to present a different perspective compared with more common non-equal area, north-up maps. [1] This goal is similar to that of other equal-area projections (such as the Gall–Peters projection), but the Hobo-Dyer is billed by the publisher as "more visually satisfying". [2] To this end, the map stretches the low latitudes vertically less than Peters, but at the price of greater compression near the poles.

Gall–Peters projection specialization of a configurable equal-area map projection

The Gall–Peters projection is a rectangular map projection that maps all areas such that they have the correct sizes relative to each other. Like any equal-area projection, it achieves this goal by distorting most shapes. The projection is a particular example of the cylindrical equal-area projection with latitudes 45° north and south as the regions on the map that have no distortion.

In 2002, the Carter Center used the Hobo–Dyer projection in a map of its global locations that it circulated to mark its founder Jimmy Carter's receipt of the Nobel Peace Prize. [3]

Carter Center American nonprofit organization

The Carter Center is a nongovernmental, not-for-profit organization founded in 1982 by former U.S. President Jimmy Carter. He and his wife Rosalynn Carter partnered with Emory University just after his defeat in the 1980 U.S. Presidential elections. The center is located in a shared building adjacent to the Jimmy Carter Library and Museum on 37 acres (150,000 m2) of parkland, on the site of the razed neighborhood of Copenhill, two miles (3 km) from downtown Atlanta, Georgia. The library and museum are owned and operated by the United States National Archives and Records Administration, while the Center is governed by a Board of Trustees, consisting of business leaders, educators, former government officials, and philanthropists.

Jimmy Carter 39th president of the United States

James Earl Carter Jr. is an American politician and philanthropist who served as the 39th president of the United States from 1977 to 1981. A member of the Democratic Party, he previously served as a Georgia State Senator from 1963 to 1967 and as the 76th Governor of Georgia from 1971 to 1975. After his presidency, Carter has remained active in the private sector; in 2002, he was awarded the Nobel Peace Prize for his work in co-founding the Carter Center.

Nobel Peace Prize One of five Nobel Prizes established by Alfred Nobel

The Nobel Peace Prize is one of the five Nobel Prizes established by the will of Swedish industrialist, inventor, and armaments manufacturer Alfred Nobel, along with the prizes in Chemistry, Physics, Physiology or Medicine, and Literature. Since March 1901, it has been awarded annually to those who have "done the most or the best work for fraternity between nations, for the abolition or reduction of standing armies and for the holding and promotion of peace congresses".

Asia Earths largest and most populous continent, located primarily in the Eastern and Northern Hemispheres

Asia is Earth's largest and most populous continent, located primarily in the Eastern and Northern Hemispheres. It shares the continental landmass of Eurasia with the continent of Europe and the continental landmass of Afro-Eurasia with both Europe and Africa. Asia covers an area of 44,579,000 square kilometres (17,212,000 sq mi), about 30% of Earth's total land area and 8.7% of the Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations. Asia is notable for not only its overall large size and population, but also dense and large settlements, as well as vast barely populated regions. Its 4.5 billion people constitute roughly 60% of the world's population.

Henry Kissinger 56th United States Secretary of State

Henry Alfred Kissinger is an American politician, diplomat, and geopolitical consultant who served as United States Secretary of State and National Security Advisor under the presidential administrations of Richard Nixon and Gerald Ford. A Jewish refugee who fled Nazi Germany with his family in 1938, he became National Security Advisor in 1969 and U.S. Secretary of State in 1973. For his actions negotiating a ceasefire in Vietnam, Kissinger received the 1973 Nobel Peace Prize under controversial circumstances, with two members of the committee resigning in protest. Kissinger later sought, unsuccessfully, to return the prize after the ceasefire failed.

Map projection Systematic representation of the surface of a sphere or ellipsoid onto a plane

A map projection is a systematic transformation of the latitudes and longitudes of locations from the surface of a sphere or an ellipsoid into locations on a plane. Maps cannot be created without map projections. All map projections necessarily distort the surface in some fashion. There is no limit to the number of possible map projections.

Roosevelt, Seattle neighborhood in north Seattle

Roosevelt is a neighborhood in north Seattle, Washington. Its main thoroughfare, originally 10th Avenue, was renamed Roosevelt Way upon Theodore Roosevelt's death in 1919. The neighborhood received the name as the result of a Community Club contest held eight years later, in 1927.

After his death in 1896, the will of Swedish industrialist Alfred Nobel established the Nobel Prizes. Nobel's will specified that annual prizes are to be awarded for service to humanity in the fields of physics, chemistry, physiology or medicine, literature, and peace. Similarly, the Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel is awarded along with the Nobel Prizes. Since the first award in 1901, the prizes have occasionally engendered criticism and controversy.

South-up map orientation map with South at the top

South-up map orientation is the orientation of a map with south up, or at the top of the map, amounting to a 180-degree rotation of the map from the standard convention of north-up. Maps in this orientation are sometimes called upside down maps or reversed maps.

Equirectangular projection map projection that maps meridians and parallels to vertical and horizontal straight lines, respectively, producing a rectangular grid

The equirectangular projection is a simple map projection attributed to Marinus of Tyre, who Ptolemy claims invented the projection about AD 100. The projection maps meridians to vertical straight lines of constant spacing, and circles of latitude to horizontal straight lines of constant spacing. The projection is neither equal area nor conformal. Because of the distortions introduced by this projection, it has little use in navigation or cadastral mapping and finds its main use in thematic mapping. In particular, the plate carrée has become a standard for global raster datasets, such as Celestia and NASA World Wind, because of the particularly simple relationship between the position of an image pixel on the map and its corresponding geographic location on Earth.

Lambert cylindrical equal-area projection

In cartography, the Lambert cylindrical equal-area projection, or Lambert cylindrical projection, is a cylindrical equal-area projection. This projection is undistorted along the equator, which is its standard parallel, but distortion increases rapidly towards the poles. Like any cylindrical projection, it stretches parallels increasingly away from the equator. The poles accrue infinite distortion, becoming lines instead of points.

Equal Earth projection pseudocylindrical, equal-area map projection

The Equal Earth map projection is an equal-area pseudocylindrical projection for world maps, invented by Bojan Šavrič, Bernhard Jenny, and Tom Patterson in 2018. It is inspired by the widely used Robinson projection, but unlike the Robinson projection, retains the relative size of areas. The projection equations are simple to implement and fast to evaluate.
