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. 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. The mercator map was designed as an aid to navigators since straight lines on the mercator projection are loxodromes or rhumb lines - representing lines of constant compass bearing - perfect for 'true' direction.

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. 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. What it shows as shown in the drawing, the mercator projection is a cylindrical map projection of the spherical globe the meridians and parallels of latitude on the globe end up appearing as lines crossing at right angles in the projection.

Use of the mercator map projection as the base for nautical charts is universal examples are the charts published by the national ocean survey, us dept of commerce oblique mercator conformal meridians are complex curves concave toward the line of tangency, except each 180th meridian is straight. Mercator world map nova et aucta orbis terrae descriptio ad usum navigatium emendate (1569) the mercator projection is a cylindrical map projection presented by the flemish geographer and cartographer gerardus mercator, in 1569. Mercator projection the mercator projection is a map projection that was widely used for navigation since loxodromes are straight lines (although great circles are curved) the following equations place the x-axis of the projection on the equator and the y-axis at longitude, where is the longitude and is the latitude. Mercator puzzle ¶ redux — by bramus drag the shapes to their correct location if you don't know the position of a country, double click it to let the computer place it hit refresh to get a new set of shapes. It turns out monday was steve waterman's birthday his site has posters of his map, plus maybe the world's only winkel tripel-critiquing poetry.

Mercator projection definition, a conformal projection on which any rhumb line is represented as a straight line, used chiefly in navigation, though the scale varies with latitude and areal size and the shapes of large areas are greatly distorted. Our world of mercator’s projection map mural celebrates the legacy of the c16th cartographer gerardus mercator mercator is most famous for his production of a map in 1569 that was based on a new projection which represented sailing courses of constant bearing as straight lines. 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. 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.

Mercator projection the mercator projection is a cylindrical map projection developed by gerardus mercator in 1569 it became the standard map projection for nautical purposes because of its ability to represent lines of constant true bearing as straight line segments. 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. Using the mercator projection as an example, describe what can happen when a map projection is used for a purpose for which it is not designed michal young , software guy who knows a bit about maps answered sep 17, 2015 author has 573 answers and 4875k answer views.

Due to this, the mercator projection made world exploration much easier and became a essential map projection for navigation using a cylinder and a globe with light is a simplified explanation as to how the mercator projection works. The size of the grid depends on the map zoom level at the lowest zoom level, the world is contained in one map tile at the next higher zoom level, the world is two tiles wide and two tiles high (2x2), at the next level above that, the grid is 4x4, then 8x8, 16x16, and so on up to the maximum zoom for a particular region.

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 projection is designed so that lines of constant bearing on the earth correspond to straight lines on the map for example, the course of a ship sailing northeast is a straight line on the map. 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 navigation because of its ability to represent lines of constant course,.
