Figure-ground Contrast (cartography)
Figure-ground contrast, in the context of map design, is a property of a map in which the map image can be partitioned into a single feature or type of feature that is considered as an object of attention (the ''figure''), with the remainder of the map being relegated to the background, outside the current focus of attention.Tait, Alex (2018Visual Hierarchy and Layout ''The Geographic Information Science & Technology Body of Knowledge (2nd Quarter 2018 Edition)'', John P. Wilson (ed.). DOI: 10.22224/gistbok/2018.2.4 It is thus based on the concept of figure–ground from Gestalt psychology. For example, in a street map with strong figure-ground contrast, the reader would be able to isolate and focus attention on individual features, like a given street, park, or lake, as well as layers of related features, like the street network. Strong figure-ground contrast has been seen as a desirable goal of map design, because it helps the map reader to perceive distinct geographic phenomen ...

Perceptual Psychology
Perceptual psychology is a subfield of cognitive psychology that concerns the conscious and unconscious innate aspects of the human cognitive system: perception. A pioneer of the field was James J. Gibson. One major study was that of affordances, i.e. the perceived utility of objects in, or features of, one's surroundings. According to Gibson, such features or objects were perceived as affordances and not as separate or distinct objects in themselves. This view was central to several other fields as software user interface and usability engineering, environmentalism in psychology, and ultimately to political economy where the perceptual view was used to explain the omission of key inputs or consequences of economic transactions, i.e. resources and wastes. Gerard Egan and Robert Bolton explored areas of interpersonal interactions based on the premise that people act in accordance with their perception of a given situation. While behaviour is obvious, a person's thoughts and feelings ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Contour Line
A contour line (also isoline, isopleth, or isarithm) of a function of two variables is a curve along which the function has a constant value, so that the curve joins points of equal value. It is a plane section of the three-dimensional graph of the function f(x,y) parallel to the (x,y)-plane. More generally, a contour line for a function of two variables is a curve connecting points where the function has the same particular value. In cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. A contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes. The contour interval of a contour map is the difference in elevation between successive contour lines. The gradient of the function is always perpendicular to the contour lines. When the lines are close together the magnitude of the grad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ocean
The ocean (also the sea or the world ocean) is the body of salt water that covers approximately 70.8% of the surface of Earth and contains 97% of Earth's water. An ocean can also refer to any of the large bodies of water into which the world ocean is conventionally divided."Ocean."

Continent
A continent is any of several large landmasses. Generally identified by convention rather than any strict criteria, up to seven geographical regions are commonly regarded as continents. Ordered from largest in area to smallest, these seven regions are: Asia, Africa, North America, South America, Antarctica, Europe, and Australia. "Most people recognize seven continents—Asia, Africa, North America, South America, Antarctica, Europe, and Australia, from largest to smallest—although sometimes Asia and Europe are considered a single continent, Eurasia." Variations with fewer continents may merge some of these, for example America, Eurasia, or Afro-Eurasia are sometimes treated as single continents, which can bring the total number as low as four. Zealandia, a largely submerged mass of continental crust, has also been described as a continent. Oceanic islands are frequently grouped with a nearby continent to divide all the world's land into geographical regions. Under t ...

Visual Variable
A visual variable, in cartographic design, graphic design, and data visualization, is an aspect of a graphical object that can visually differentiate it from other objects, and can be controlled during the design process. The concept was first systematized by Jacques Bertin, a French cartographer and graphic designer, and published in his 1967 book, ''Sémiologie Graphique.''Jacque Bertin, ''Sémiologie Graphique. Les diagrammes, les réseaux, les cartes''. With Marc Barbut t al. Paris : Gauthier-Villars. ''Semiology of Graphics'', English Edition, Translation by William J. Berg, University of Wisconsin Press, 1983.) Bertin identified a basic set of these variables and provided guidance for their usage; the concept and the set of variables has since been expanded, especially in cartography, where it has become a core principle of education and practice.Roth, Robert EVisual Variables in D. Richardson, N. Castree, M.F. Goodchild, A. Kobayashki, W. Liu, and R.A. Marston, eds. ''The Int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arabian Sea Map
The Arabian Peninsula, (; ar, شِبْهُ الْجَزِيرَةِ الْعَرَبِيَّة, , "Arabian Peninsula" or , , "Island of the Arabs") or Arabia, is a peninsula of Western Asia, situated northeast of Africa on the Arabian Plate. At , the Arabian Peninsula is the largest peninsula in the world. Geographically, the Arabian Peninsula includes Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, the United Arab Emirates (UAE), and Yemen, as well as the southern portions of Iraq and Jordan. The largest of these is Saudi Arabia. In the classical era, the southern portions of modern-day Syria, Jordan, and the Sinai Peninsula were also considered parts of Arabia (see Arabia Petraea). The Arabian Peninsula formed as a result of the rifting of the Red Sea between 56 and 23 million years ago, and is bordered by the Red Sea to the west and southwest, the Persian Gulf and the Gulf of Oman to the northeast, the Levant and Mesopotamia to the north and the Arabian Sea and the Indian Oce ...

Perception
Perception () is the organization, identification, and interpretation of sensory information in order to represent and understand the presented information or environment. All perception involves signals that go through the nervous system, which in turn result from physical or chemical stimulation of the sensory system.Goldstein (2009) pp. 5–7 Vision involves light striking the retina of the eye; smell is mediated by odor molecules; and hearing involves pressure waves. Perception is not only the passive receipt of these signals, but it is also shaped by the recipient's learning, memory, expectation, and attention. Gregory, Richard. "Perception" in Gregory, Zangwill (1987) pp. 598–601. Sensory input is a process that transforms this low-level information to higher-level information (e.g., extracts shapes for object recognition). The process that follows connects a person's concepts and expectations (or knowledge), restorative and selective mechanisms (such as ...

Visual Hierarchy
Visual hierarchy, according to Gestalt psychology, is a pattern in the visual field wherein some elements tend to "stand out," or attract attention, more strongly than other elements, suggesting a hierarchy of importance. While it may occur naturally in any visual field, the term is most commonly used in design (especially graphic design and cartography), where elements are intentionally designed to make some look more important than others. This order is created by the visual contrast between forms in a field of perception. Objects with highest contrast to their surroundings are recognized first by the human mind. Evidence There is some scientific evidence for visual hierarchy using eye tracking. For example, one study found that when people agree that a graphic design is good, they exhibit more similar eye movements; measured by the Fréchet distance. Theory The concept of visual hierarchy is based in Gestalt psychological theory, an early 20th-century German theory that propo ...

Arthur H
Arthur Higelin (born 27 March 1966), better known under his stage name Arthur H (), is a French pianist, songwriter and singer. He is best known in France for his live performances—four of his albums were recorded live. Life and career He is the son of the French singer Jacques Higelin and Nicole Courtois, and half brother of singers Izïa Higelin and stage and film actor, theatre director and music video director Kên Higelin. After traveling in the West Indies, he studied music in Boston before returning to Paris and developing his eclectic but highly personal musical style, drawing on such influences as Thelonious Monk, Serge Gainsbourg, the Sex Pistols, jazz, blues, Middle Eastern music and the tango. He first performed in 1988 in clubs in Paris, as leader of a trio with bassist Brad Scott and drummer Paul Jothy. His first album, ''Arthur H'' (1990), combined rhythmic experimentation and ''bal-musette'' elements with a vocal style which has been compared to Tom Waits. He ...

Figure–ground (perception)
Figure–ground organization is a type of perceptual grouping that is a vital necessity for recognizing objects through vision. In Gestalt psychology it is known as identifying a ''figure'' from the back''ground''. For example, black words on a printed paper are seen as the "figure", and the white sheet as the "background". Gestalt psychology The Gestalt theory was founded in the 20th century in Austria and Germany as a reaction against the associationist and structural schools’ atomistic orientation. In 1912, the Gestalt school was formed by Max Wertheimer, Wolfgang Köhler, and Kurt Koffka. The word "gestalt" is a German word translated to English as "pattern" or "configuration." Gestalt concepts can also be referred to as "holism." Gestalt Psychologists were attempting to humanize what was considered a sterile approach. Gestalt psychology establishes that the whole of anything is greater than its parts. The concepts explored by Wertheimer, Köhler, and Koffka in the 2 ...

Robot
A robot is a machine—especially one programmable by a computer—capable of carrying out a complex series of actions automatically. A robot can be guided by an external control device, or the control may be embedded within. Robots may be constructed to evoke human form, but most robots are task-performing machines, designed with an emphasis on stark functionality, rather than expressive aesthetics. Robots can be autonomous or semi-autonomous and range from humanoids such as Honda's ''Advanced Step in Innovative Mobility'' ( ASIMO) and TOSY's ''TOSY Ping Pong Playing Robot'' (TOPIO) to industrial robots, medical operating robots, patient assist robots, dog therapy robots, collectively programmed ''swarm'' robots, UAV drones such as General Atomics MQ-1 Predator, and even microscopic nano robots. By mimicking a lifelike appearance or automating movements, a robot may convey a sense of intelligence or thought of its own. Autonomous things are expected to proliferate in ...
