Cartography is the study and practice of making and using maps. Combining science, aesthetics and technique, cartography builds on the premise that reality can be modeled in ways that communicate spatial information effectively.
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.
A map is a symbolic depiction emphasizing relationships between elements of some space, such as objects, regions, or themes.
An atlas is a collection of maps; it is typically a bundle of maps of Earth or of a continent or region of Earth.
In cartography, a map projection is any of a broad set of transformations employed to represent the curved two-dimensional 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.
Gerardus Mercator was a Flemish geographer, cosmographer and cartographer. He is most renowned for creating the 1569 world map based on a new projection which represented sailing courses of constant bearing as straight lines—an innovation that is still employed in nautical charts.
Arthur H. Robinson was an American geographer and cartographer, who was professor in the Geography Department at the University of Wisconsin–Madison from 1947 until he retired in 1980. He was a prolific writer and influential philosopher on cartography, and one of his most notable accomplishments is the Robinson projection of 1961.
The earliest known world maps date to classical antiquity, the oldest examples of the 6th to 5th centuries BCE still based on the flat Earth paradigm. World maps assuming a spherical Earth first appear in the Hellenistic period. The developments of Greek geography during this time, notably by Eratosthenes and Posidonius culminated in the Roman era, with Ptolemy's world map, which would remain authoritative throughout the Middle Ages. Since Ptolemy, knowledge of the approximate size of the Earth allowed cartographers to estimate the extent of their geographical knowledge, and to indicate parts of the planet known to exist but not yet explored as terra incognita.
The history of cartography refers to the development and consequences of cartography, or mapmaking technology, throughout human history. Maps have been one of the most important human inventions for millennia, allowing humans to explain and navigate their way through the world.
Giacomo Gastaldi was an Italian cartographer, astronomer and engineer of the 16th century. Gastaldi began his career as an engineer, serving the Venetian Republic in that capacity until the fourth decade of the sixteenth century. From about 1544 he turned his attention entirely to mapmaking, and his work represents several important turning points in cartographic development.
Pictorial maps depict a given territory with a more artistic rather than technical style. It is a type of map in contrast to road map, atlas, or topographic map. The cartography can be a sophisticated 3-D perspective landscape or a simple map graphic enlivened with illustrations of buildings, people and animals. They can feature all sorts of varied topics like historical events, legendary figures or local agricultural products and cover anything from an entire continent to a college campus. Drawn by specialized artists and illustrators, pictorial maps are a rich, centuries-old tradition and a diverse art form that ranges from cartoon maps on restaurant placemats to treasured art prints in museums.
The International Cartographic Association (ICA) is an organization formed of national member organizations, to provide a forum for issues and techniques in cartography and geographic information science (GIScience). ICA was founded on June 9, 1959, in Bern, Switzerland. The first General Assembly was held in Paris in 1961. The mission of the International Cartographic Association is to promote the disciplines and professions of cartography and GIScience in an international context. To achieve these aims, the ICA works with national and international governmental and commercial bodies, and with other international scientific societies.
Nicolaus Germanus was a German cartographer who modernized Ptolemy's Geography by applying new projections, adding additional maps, and contributing other innovations that were influential in the development of Renaissance cartography.
The Nuzhat al-mushtāq fī ikhtirāq al-āfāq, commonly known in the West as the Tabula Rogeriana, is an atlas commissioned by the Norman King Roger II in 1138 and completed by the Arab geographer Muhammad al-Idrisi in 1154. The atlas compiles 70 maps of the known world with associated descriptions and commentary of each specific location by Al-Idrisi.
Critical cartography is a set of mapping practices and methods of analysis grounded in critical theory, specifically the thesis that maps reflect and perpetuate relations of power, typically in favor of a society's dominant group. Critical cartographers aim to reveal the “‘hidden agendas of cartography’ as tools of socio-spatial power”. While the term "critical cartography" often refers to a body of theoretical literature, critical cartographers also call for practical applications of critical cartographic theory, such as counter-mapping, participatory mapping, and neogeography.
Borden D. Dent (1938–2000) was an American geographer and cartographer who served as professor emeritus and chairman of the Department of Geography and Anthropology at Georgia State University. His textbook, Cartography: Thematic Map Design, is one of the seminal texts in the field, and its sixth edition was reissued in 2009.
Cartographic propaganda is a map created with the goal of achieving a result similar to traditional propaganda. The map can be outright falsified, or created using subjectivity with the goal of persuasion. The idea that maps are subjective is not new; cartographers refer to maps as a human-subjective product and some view cartography as an "industry, which packages and markets spatial knowledge" or as a communicative device distorted by human subjectivity. However, cartographic propaganda is widely successful because maps are often presented as a miniature model of reality, and it is a rare occurrence that a map is referred to as a distorted model, which sometimes can "lie" and contain items that are completely different from reality. Because the word propaganda has become a pejorative, it has been suggested that mapmaking of this kind should be described as "persuasive cartography", defined as maps intended primarily to influence opinions or beliefs – to send a message – rather than to communicate geographic information.
A General Map of the World, or Terraqueous Globe, full title: A General Map of the World, or Terraqueous Globe with all the New Discoveries and Marginal Delineations, Containing the Most Interesting Particulars in the Solar, Starry and Mundane System, is a general map of the world, or terraqueous globe with all the new discoveries and marginal delineations, containing interesting particulars in the solar, starry and mundane system by Samuel Dunn and Thomas Kitchin in 1794. The map features star charts, a map of the Moon, a map of the Solar System, and numerous other features along with maps of both hemispheres of the Earth. Samuel Dunn's map is large and includes much detail, and is challenging to fully describe it in small photographs or text.
Cartographic design or map design is the process of crafting the appearance of a map, applying the principles of design and knowledge of how maps are used to create a map that has both aesthetic appeal and practical function. It shares this dual goal with almost all forms of design; it also shares with other design, especially graphic design, the three skill sets of artistic talent, scientific reasoning, and technology. As a discipline, it integrates design, geography, and geographic information science.
Alexander James Kent is a British cartographer, geographer and academic, currently serving as Vice President of the International Cartographic Association. He leads the Coastal Connections Project for World Monuments Fund and English Heritage and is honorary Reader in Cartography and Geographical Information Science at Canterbury Christ Church University (CCCU) and also a senior research associate of the Oxford Centre for Islamic Studies at the University of Oxford.
