Mercator projection

As in all cylindrical projectionsparallels and meridians are straight and perpendicular to each other. In accomplishing this, the unavoidable east-west stretching of the map, which increases as distance away from the equator increases, is accompanied in the Mercator projection by a corresponding north-south stretching, so that at every point location the east-west scale is the same as the north-south scale, making it a conformal map projection. Conformal projections preserve angles around all locations.

The Challenge Which is bigger, Greenland or China?

Mercator projection

With the traditional Mercator map circaand still in use in many schoolrooms and boardrooms todayGreenland and China look the same size. But in reality China is almost 4 times larger! In response to such discrepancies, Dr.

Mercator projection - Wikipedia

Arno Peters created a new world map that dramatically improves the accuracy of how we see the Earth. Mercator's projection created at a time when navigators were sailing on the oceans in wooden ships, powered by the wind, and navigating by the stars was particularly useful because straight lines on his projection were lines of constant compass bearing.

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 size accurately. If you want a true shape for the land masses you will necessarily sacrifice proportionality, i.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. Mapping Earth or Trapping Minds?


Story of Mercator Projection. General Knowledge Fact: India is the 7th largest country in the world in terms of Geographical area. The Mercator projection is everywhere. If you went to public school any time before , this is the map projection that told you Greenland was the size of Africa, Alaska was bigger than Brazil, and Antarctica was an infinite, frozen nightmare.

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 . Waypoint Projector Project a Waypoint. Acceptable inputs are: Latitude, Longitude (NS+-)DD MM, (WE+-)DDD MM (NS+-)DD, (WE+-)DDD Mercator projection: Mercator projection, a map projection introduced by Flemish cartographer Gerardus Mercator in 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.
