Mercator projection map

Henry Miller Oct 31, A lot of people have problems with the Mercator map of the world.

Mercator projection pros and cons

The criticisms leveled against inappropriate use of the Mercator projection resulted in a flurry of new inventions in the late 19th and early 20th century, often directly touted as alternatives to the Mercator. However, it did not begin to dominate world maps until the 19th century, when the problem of position determination had been largely solved. But from an objective perspective, there are other possibilities I prefer. We begin with the projection you are likely to be most familiar with. Alone, this would still skew a line of bearing. Mercator lived in a rapidly changing world in which states gained power through their mastery of ocean travel. A brief history of the Mercator Projection It is surprisingly difficult for geographers and cartographers to accurately portray a 3-dimensional sphere on a 2-dimensional surface. And already it is starting to take hold over there as the map projection of choice. They are the conformal, equivalent, equidistant and azimuthal projections. 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. Maps , and others use a variant of the Mercator projection for their map images [13] called Web Mercator or Google Web Mercator.

Many other online mapping services still exclusively use the Web Mercator. The sizes are only slightly distorted, as are the shapes.

A cylindrical projection is when a cylinder is used to construct a projection, a cone for the conic and a flat plane for the azimuthal. The further they moved from the equator, the greater the distance between them became.

As a result, it became a standard map for classrooms. Distortion of sizes[ edit ] A relation between the Mercator projection and the true size of each country. Russia appears to be 4 times the size of the United Statesbut is really only about twice the size; comparable to the size of South America.

Unlike the Winkel-Tripel, the Authagraph is rectangular, which makes it easier to work with from a cartographic perspective, and also better suited to presentation. The cylinder, however, was perpendicular to this point, and as the globe curved in from the paper, the lines of longitude stayed straight rather than meeting at the poles.
