Authagraph is a kind of equal-area globe map projection designed in 1999 by Japanese architect Hajime Narukawa. The map maintains the sizes of all continents and seas while eliminating form distortions, like a Dymaxion map does. It has been described as "a perfect map because it displays the entire world without any distortion or overlap".
The projection was created to provide a view of the world that is both accurate and attractive. It uses spherical geometry, so the distances between all locations on the surface of Earth are always equal. This means that anywhere you go on Earth, no matter how far you travel, you are always at a constant distance from home. A second advantage of this map projection is its ability to display large areas without distortion or overlapping. Indeed, unlike other projections which enlarge near the poles, the authors of this map design kept areas close to the equator as well as the poles intact in size.
This equal-area map projection was adopted by Google in 2005 when they developed their World_Data layer for Google Maps. The name "Authagraph" comes from the fact that the projection was invented by Narukawa Hidetoshi, who is known as an authority on graph theory within his field. The term "authograph" refers to a drawing made with ink on paper, so this map projection would produce identical results to actual trips around the world.
Hajime Narukawa, a Japanese architect, may have built the most accurate map of the world yet using a novel map-making process called AuthaGraph. AuthaGraph splits the globe into 96 triangles, which are then transferred to a tetrahedron and unfolded into a rectangle. The final product is rated 90% accurate.
Maps can be divided into four general categories: political, physical, tourist, and astronomical. Political maps show countries with different colors or symbols to indicate their respective governments or other relationships between those countries. Physical maps show information about the earth's surface, such as land masses, oceans, and deserts. Tourist maps show places of interest or value. Astronomical maps show the constellations above each point on the map, helping people find their way at night.
Mapping projects begin with research to determine what will go on the map. This could include interviewing people around the subject, looking at previous maps for comparison, or using remote sensing technology (radar, satellites, etc.) to gather data on the topic. After determining what will go on the map, a designer creates a sketch of the map layout based on this information. This initial design is usually not used in its entirety since many changes might need to be made during construction. For example, if it is discovered that a building will obscure part of the landscape, this area might have to be removed from the map or adjusted in some other way.
AuthaGraph This is without a doubt the most accurate map projection available. In fact, the AuthaGraph World Map is so perfectly proportioned that it folds into a three-dimensional globe. Hajime Narukawa, a Japanese architect, created this projection in 1999 by evenly splitting a spherical surface into 96 triangles. The result is that all places on Earth are projected onto a two-dimensional plane, with the equator appearing as a straight line and all other places following a curved path.
Lambert This projectinon uses an orthographic projection where lines of latitude and longitude remain perpendicular to the image plane. Thus, all points on the surface of Earth are projected onto the plane, but no distortions occur at high latitudes or near the poles. Originally proposed by French geographer Pierre Lambert in 1671, this projection is still used today for world maps and large-scale plans.
Mercator This is an example of a conformal map projection. It preserves angles between pairs of directions on the sphere while changing lengths of other directions. The effect is to make small objects look smaller and large ones look larger on the map than they do on Earth. English cartographer John Mercator first published his world map in 1569, and this type of projection has remained popular since then. It is especially useful when looking at details at small scales because it minimizes distortion at those sizes.
As we've seen, maps are "symbolized representations" of the planet. They portray actual and, in most cases, palpable aspects of the planet. If we wanted to, we could discover the region of the world that each given map portrays.
In literature, a map is a visual representation of something else. Thus, a literary map is a graphic depiction of some aspect(s) of a setting or story. A literary map can also be used to indicate movement through a story or setting.
Maps have been used in literature for many centuries. The first map that is known to exist was created by Piri Reis around 1480. It is now kept in the British Museum.
Landmarks, cities, and other features on the map can be recognized today, although their names aren't known yet. But even without names, we can still learn much from this early map. For example, we can see that Europe was not connected to Asia by land travel until 1553 when Portuguese explorer Ferdinand Magellan completed his journey with five ships.
Maps have been used extensively in fiction.
Certain map projections, or methods of portraying the Earth in the most accurate scale possible, are more well-known and widely used than others. The three most popular forms of map projections are cylindrical, conic, and azimuthal. Each one has advantages for certain applications.
Cylindrical maps rotate the whole world around an axis that is parallel to the equator, thereby showing everything on a circle with the poles at the center. These maps are commonly used for global overviews because they preserve both high-latitude and low-latitude features. The only problem with this map type is that all directions are equal distance from the center, so it's not useful for finding specific locations within the world.
Conic maps distort the shape of the globe but try to keep its overall size constant. Thus, they show things closer together at the top of the map and farther apart at the bottom. This helps to reduce clutter on global scales while still showing detail at local levels. Conic maps are often used in road atlases and other regional maps because they allow you to see relationships between cities and towns across large distances. However, they don't work as well for showing location within a city because everything is clustered near the center.
