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. Peters is an equal-area projection which became the centrepiece of a controversy surrounding the political implications of map design the argument goes something like this: mercator inflates the . Like symphonies, map projections are named after their makers gerardus mercator was an engraver and globe-maker in 1500s flanders until he came along, most cartographers were using ptolemy’s .

Modeled and animated by grafonaut video as part of a course by emarin norway explaining the sacrifices made to convert the earths spherical surface into a . This schematic appears in the handbook that accompanied the1983 landsat short course lecture on “tm data processing and correction” that was given by jeff dozier of ucsb to continually map the earth’s surface using landsat data, an entirely new projection had to be created this new .
Mercator projection is a method of creating a rectangular flat map with a grid of vertical lines representing longitude lines and horizontal lines representing latitude. Gerardus mercator invented his famous projection in 1569 as an aid to navigators on his map, lines of latitude and longitude intersect at right angles and thus the direction of travel—the rhumb line—is consistent. 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 disadvantages. 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 . 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.
Although the mercator projection significantly distorts scale and area (particularly near the poles), it has two important properties that outweigh the scale distortion:. Buy rhumb lines and map wars: a social history of the mercator projection on amazoncom free shipping on qualified orders. Up until now, google maps has used mercator projection, which projects the planet onto a flat surface while this style makes it easy to print onto maps and has largely become standardized, it . 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.
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. : 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 . Making accurate world maps is mathematically impossible subscribe to our channel interact with projections: .

The mercator projection is a a cylindrical map projection that represents lines of constant true bearing as straight line segments. Universal transverse mercator (utm) projection start with a sphere or ellipsoid because that is the true form of the earth peel it like an orange evenly into sixty segments called “zones”. Pseudocylindrical projections pseudocylindrical projections resemble cylindrical projections, with straight and parallel latitude lines and equally spaced meridians, but the other meridians are curves.
