Given how popular the mercator projection is, it's wise to question how it makes us view the world many have noted, for example, how the distortion around the poles makes africa look smaller than. The universal transverse mercator (utm) projection is used to define horizontal, positions world-wide by dividing the surface of the earth into 6 degree zones, each mapped by the transverse mercator projection with a central meridian in the center of the zone. 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. The three main families of map projections unwrapping the sphere to a plane mercator projection miller projection plate carrée projection universal transverse mercator projection pseudocylindrical map projections all cylindrical projections fill a rectangular plane.

Mercator the most popular map projection in the world has been around for 448 years now it was created by flemish cartographer gerardus mercator in 1569 – a time when antarctica hadn’t even been discovered mercator was designed as a navigational tool for sailors as it was most convenient to hand-plot courses with parallel rules and. 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. D3-geo map projections are sometimes implemented as point transformations for instance, spherical mercator: function mercator (x, the spherical mercator projection defines a default projectionclipextent such that the world is projected to a square, clipped to approximately ±85° latitude. The mercator projection is a cylindrical projection that was developed for navigation purposes the mercator projection was used for its portrayal of direction and shape, so it was helpful to the sailors of that time.

The mercator projection was originally developed in 1569 by the flemish cartographer gerardus mercator at this time, many of europe’s top cartographers and explorers used elliptical projections derived from ptolemy’s latitude and longitude grid. 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 that conserve the angles with. The mercator projection was one of the first important maps created by europeansit was produced by gerard mercator, a flemish mapmaker who lent his name to his famous work on such a map, the east-west and north-south lines are straight lines because the world is round, this makes for some not-so-accurate geographical representations.

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. 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. Mercator projection lies when comparing conformal mercator projection (black lines) and equal area gall-peters projection (green shapes) you can notice that the world as we know it from google maps is a lie. La projection de mercator est un procédé pour représenter la surface de la terre (qui est sphérique) sur une carte (qui est plane) la projection permet la représentation de la totalité de la surface de la terre donc d'établir des planisphères.

La projection de mercator ou projection mercator est une projection cylindrique tangente à l'équateur du globe terrestre sur une carte plane formalisée par le géographe flamand, gerardus mercator en 1569 elle s'est imposée comme le planisphère standard dans le monde grâce à sa précision pour les voyages marins. Map projections a map projection is used to portray all or part of the round earth on a flat surface this cannot be done without some distortion every projection has its own set of advantages and usgs topographic map based on the transverse mercator projection is nearly correct in every respect. Die in der kartografie verwendete mercator-projektion ist eine nach dem kartografen gerhard mercator benannte form der zylinderprojektion, bei der die projektion in richtung der zylinderachse geeignet verzerrt ist, um eine winkeltreue abbildung der erdoberfläche zu erreichen. The mercator projection doesn’t preserve area correctly, especially as you get closer to the poles on the other hand, one kind of projection that doesn’t distort area is the cylindrical equal area notice here how greenland looks the right size as compared to south america.

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 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 utmwhen paired with a suitable geodetic datum, the transverse mercator delivers high accuracy in zones less than a few degrees in east-west extent. Mercator’s map was so useful to sailors that its popularity eventually caught on with landlubbers today, it’s still the most often used map projection in the world. In the 16 th century, mercator developed a world map mainly used for ocean navigation, and this projection is still used to this day for a number of purposes the land masses, however, are distorted in shape and size.

- Proponents of the peters projection map claim that their map is a good, fair, and non-racist view of the world they're comparing their map to the almost-defunct mercator map unfortunately, geographers and cartographers agree that neither map projection is appropriate for use as a map of our planet.
- L’originalité de mercator repose sur la projection de la surface terrestre sur un cylindre tangent à l’équateur ce qui présente l’avantage de ne pas déformer les angles.
- The mercator projection is sometimes inappropriately used in atlases for maps of the world, and for wall coordinate systems and map projections non-published educational notes, it c, enschede, 1998 ra knippers geometric aspects of mapping.

Some of the oldest projections are equal-area (the sinusoidal projection is also known as the mercator equal-area projection), and hundreds have been described, refuting any implication that peters's map is special in that regard. Mercator projection mercator projection n a cylindrical map projection in which the meridians and parallels appear as lines crossing at right angles and in which areas appear greater farther from the equator straight line segments represent true bearings, thus making this projection useful for navigation [after gerhardus mercator] mercator.
