Topological Map
In cartography, geology, and robotics, a topological map is a type of diagram that has been simplified so that only vital information remains and unnecessary detail has been removed. These maps lack scale, also distance and direction are subject to change and/or variation, but the topological relationship between points is maintained. A good example are the tube maps for the London Underground and the New York City Subway.

Dervish Example
Dervish, Darvesh, or Darwīsh (from ) in Islam can refer broadly to members of a Sufi fraternity (''tariqah''), or more narrowly to a religious mendicant, who chose or accepted material poverty. The latter usage is found particularly in Persian and Turkish (''derviş'') as well as in Tamazight (''Aderwic''), corresponding to the Arabic term '' faqīr''. Their focus is on the universal values of love and service, deserting the illusions of ego (''nafs'') to reach God. In most Sufi orders, a dervish is known to practice ''dhikr'' through physical exertions or religious practices to attain the ecstatic trance to reach God. Their most popular practice is Sama, which is associated with the 13th-century mystic Rumi. In folklore and with adherents of Sufism, dervishes are often credited with the ability to perform miracles and ascribed supernatural powers. Historically, the term Dervish has also been used more loosely, as the designation of various Islamic political movements or mil ...

Cartography
Cartography (; from , '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 the mapped object's characteristics that are irrelevant to the map's purpose. This is the concern of Cartographic generalization, generalization. * Reduce the complexity of the characteristics that will be mapped. This is also the concern of generalization. * Orchestrate the elements ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Geology
Geology (). is a branch of natural science concerned with the Earth and other astronomical objects, the rocks of which they are composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology. It is integrated with Earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface and the processes that have shaped that structure. Geologists study the mineralogical composition of rocks in order to get insight into their history of formation. Geology determines the relative ages of rocks found at a given location; geochemistry (a branch of geology) determines their absolute ages. By combining various petrological, crystallographic, and paleontological tools, geologists are able to chronicle the geological history of the Earth as a whole. One aspect is to demonstrate the age of the Earth. Geology provides evidence for plate tectonics, the ev ...

Diagram
A diagram is a symbolic Depiction, representation of information using Visualization (graphics), visualization techniques. Diagrams have been used since prehistoric times on Cave painting, walls of caves, but became more prevalent during the Age of Enlightenment, Enlightenment. Sometimes, the technique uses a Three-dimensional space, three-dimensional visualization which is then graphical projection, projected onto a two-dimensional surface. The word ''graphics, graph'' is sometimes used as a synonym for diagram. Overview The term "diagram" in its commonly used sense can have a general or specific meaning: * ''visual information device'' : Like the term "illustration", "diagram" is used as a collective term standing for the whole class of technical genres, including graphics, graphs, technical drawings and tables. * ''specific kind of visual display'' : This is the genre that shows qualitative data with shapes that are connected by lines, arrows, or other visual links.

Cartographic Generalization
Cartographic generalization, or map generalization, includes all changes in a map that are made when one derives a scale (map), smaller-scale map from a larger-scale map or map data. It is a core part of cartographic design. Whether done manually by a cartographer or by a computer or set of algorithms, generalization seeks to abstract geospatial information, spatial information at a high Level of detail (computer graphics), level of detail to information that can be rendered on a map at a lower level of detail. The cartographer has license to adjust the content within their maps to create a suitable and useful map that conveys spatial information, while striking the right balance between the map's purpose and the precise detail of the subject being mapped. Well generalized maps are those that emphasize the most important map elements while still representing the world in the most faithful and recognizable way. History During the first half of the 20th century, cartographers began t ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Topology
Topology (from the Greek language, Greek words , and ) is the branch of mathematics concerned with the properties of a Mathematical object, geometric object that are preserved under Continuous function, continuous Deformation theory, deformations, such as Stretch factor, stretching, Torsion (mechanics), twisting, crumpling, and bending; that is, without closing holes, opening holes, tearing, gluing, or passing through itself. A topological space is a Set (mathematics), set endowed with a structure, called a ''Topology (structure), topology'', which allows defining continuous deformation of subspaces, and, more generally, all kinds of List of continuity-related mathematical topics, continuity. Euclidean spaces, and, more generally, metric spaces are examples of topological spaces, as any distance or metric defines a topology. The deformations that are considered in topology are homeomorphisms and Homotopy, homotopies. A property that is invariant under such deformations is a to ...

London Underground
The London Underground (also known simply as the Underground or as the Tube) is a rapid transit system serving Greater London and some parts of the adjacent home counties of Buckinghamshire, Essex and Hertfordshire in England. The Underground has its origins in the Metropolitan Railway, opening on 10 January 1863 as the world's first underground passenger railway. The Metropolitan is now part of the Circle line (London Underground), Circle, District line, District, Hammersmith & City line, Hammersmith & City and Metropolitan lines. The first line to operate underground electric locomotive, electric traction trains, the City & South London Railway in 1890, is now part of the Northern line. The network has expanded to 11 lines with of track. However, the Underground does not cover most southern parts of Greater London; there are only 33 Underground stations south of the River Thames. The system's List of London Underground stations, 272 stations collectively accommodate up ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Transit Map
A transit map is a topological map in the form of a schematic diagram used to illustrate the routes and stations within a public transport system—whether this be bus, tram, rapid transit, commuter rail or ferry routes. Metro maps, subway maps, or tube maps of metropolitan railways are some common examples. The primary function of a transit map is to facilitating the passengers' orientation and navigation, helping them to efficiently use the public transport system and identify which stations function as Interchange station, interchange between lines. Transit maps can usually be found in the transit vehicles, at the railway platform, platforms or in printed public transport timetable, timetables. They are also accessible through digital platforms like Mobile app, mobile apps and Website, websites, ensuring widespread availability and convenience for passengers. History The mapping of transit systems was at first generally geographically accurate, but abstract route-maps of ...
