A method of making maps in which the earth's surface is shown with the meridians as parallel straight lines spaced at equal intervals and the parallels of latitude as parallel straight lines intersecting the meridians at right angles but spaced farther apart as their distance from the equator increases: on such maps the area of a. Define mercator projection mercator projection synonyms, mercator projection pronunciation, mercator projection translation, english dictionary definition of 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. And methods used in the transverse mercator projection, which is out of print, and the ordnance survey pamphlet transverse mercator projection because of the increasing use of satellite navigation systems a short description of the shape of the earth and its mathematical representation are given as well as the. Today the mercator projection still remains useful for navigational purposes and is referred to by seafarers and airline pilots the mercator is also a conformal map projection this means that it shows shapes pretty much the way they appear on the globe the mapmaker's dilemma is that you cannot show both shape and. Sign of the reference latitude whose definition domain is [-90°,90°] this parameter is valueless in the mercator projection ✓ λ0, in the lcc and sp projections, is the meridian parallel to the lefthand and righthand sides of the domain in the 3 projections, it defines the y axis (abscissa x=0) on the opposite meridian (the one.
The projection we have used is commonly known as the mercator projection (a projection being any method of representing the surface of a sphere on to a flat plane) the mercator is well-known and familiar: it is the standard map used in most schoolbooks and newspapers it arguably has the clearest. In gis and other mapping it is important to choose an appropriate map projection to accurately depict the earth's surface a map projection is defined as a tool that transforms the earth's surface into a flat plane that can be shown on paper and/or digital maps map projections are based on an arrangement of. Mercator projection in the geography topic by longman dictionary of contemporary english | ldoce | what you need to know about geography: words, phrases and expressions | geography.
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. 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 see more.
Though maps before and after have been better at showing us the whole earth, mercator's was the first that gave us a means for exploring it if you have a beef with what your social studies teacher hung over the blackboard, better chalk it up to inertia mercator never meant for his map to teach geography. Define mercator projection: a conformal map projection of which the meridians are usually drawn parallel to each other and the parallels of latitude.
Classification, conformal cylindrical available forms, forward and inverse, spherical and elliptical projection defined area, global, but best used near the equator implemented by, gerald i evenden options +lat_ts, latitude of true scale defaults to 00 +k_0, scaling factor defaults to 10. The name and explanations given by mercator to his world map (nova et aucta orbis terrae descriptio ad usum navigantium emendata: new and augmented description of earth corrected for the use of sailors) show that it was expressly conceived for the use of marine navigation although the method of construction is. Dictionary definition of mercator projection a map projection of the earth onto a cylinder areas appear greater the farther they are from the equator similar words: mercator's projection.
42 web mercator is a map projection commonly implemented in commercial and open source data sets and internet based visualization applications web mercator mathematics are formulated on a spherical assumption of the earth which conflict with the defined wgs 84 ellipsoid reference system. A map projection of the earth onto a cylinder areas appear greater the farther they are from the equator. Because the earth is roughly spherical, every flat map distorts our planet one way or another the most popular version is the mercator projection, created by flemish cartographer gerardus mercator in 1569 it's been widely used for centuries, including today in various forms by google maps and many.
