Gerardus mercator: gerardus mercator, flemish cartographer whose most important innovation was a map, embodying what was later known as the mercator projection, on which parallels and meridians are rendered as straight lines spaced so as to produce at any point an accurate ratio of latitude to longitude. Mercator projection is an example of cylindrical projection which became a standard map projection because of its ability to represent lines of steady course mercator distorts the size of geographical objects because its linear scale increases with the increase in latitude. English: the mercator projection is a cylindrical map projection presented by the flemish geographer and cartographer gerardus mercator in 1569 it became the standard map projection for nautical purposes because of its ability to represent lines of constant course, known as rhumb lines or loxodromes, as straight segments.
The spherical mercator projection defines a default projectionclipextent such that the world is projected to a square, clipped to approximately ±85° latitude. The spherical mercator projection # d3geomiller() # d3geomillerraw the miller cylindrical projection is a modified mercator projection. The mercator projection was invented by gerardus mercator, a flemish mapmaker his name is a latinized version of gerhard kramer this is his famous world map of 1569. The peters map is an area accurate projection of the earths surface with the traditional mercator map (circa 1569, and still in use in many schoolrooms and boardrooms today), greenland and africa look the same size.
When you place a cylinder around a globe and unravel it, you get the cylindrical projection like the mercator, transverse mercator and miller projections. Mercator without a doubt, the most famous map projection is the mercator projection in fact, the mercator projection was the first projection regularly identified in atlases. Mercator never intended his map to be used for purposes other than navigation although it became one of the most popular world map projections during the 20th century, the national geographic society, various atlases, and classroom wall cartographers switched to the rounded robinson projection. The mercator projection is a cylindrical map projection presented by the flemish geographer and cartographer gerardus mercator, in 1569it became the standard map projection for nautical purposes because of its ability to represent lines of constant course, known as rhumb lines or loxodromes, as straight segments. Mercator projection definition is - a conformal map projection of which the meridians are usually drawn parallel to each other and the parallels of latitude are straight lines whose distance from each other increases with their distance from the equator.
The transverse mercator map projection is an adaptation of the standard mercator projectionthe transverse version is widely used in national and international mapping systems around the world, including the utm. Mercator projection for example in choosing the mercator projection, a popular conformal distortion, greenland appears much larger than it really is because areas are exaggerated towards the poles this map projection has properties that suite navigational uses. The mercator map projection was invented by gerardus mercator (1512-1594) born in what is now the german region, mercator was a keen cartographer and even coined the term ‘atlas’ to describe a collection of maps.
The mercator projection was one of the first important maps created by europeans it was produced by gerard mercator, a flemish mapmaker who lent his name to his famous work. For example, the basic mercator projection is unique it yields the only map on which a straight line drawn anywhere within its bounds shows a particular type of . The mercator projection is a cylindrical projection that was developed for navigation purposes the mercator projection was used for its portrayal of direction and.
Two classic map projections, one cylindrical, one azimuthal, deserve descriptions separate from their groupswhile the mercator and azimuthal equidistant projections are essential for specialized cartographic applications, the internet has spread the former's visibility and audience much beyond its intended goal. Mercator projection¶ a cylindrical, conformal projection very large distortion at high latitudes, cannot fully reach the polar regions. Mercator projection: mercator projection, a map projection introduced by flemish cartographer gerardus mercator in 1569 the mercator projection is a useful navigation tool, as a straight line on a mercator map indicates a straight course, but it is not a practical world map, because of distortion of scale near the poles. The mercator projection is a a cylindrical map projection that represents lines of constant true bearing as straight line segments.
