Mercator Projection

The Mercator projection is a cylindrical map projection presented by the Flemish geographer and cartographer Gerardus Mercator, in 1569.

Mercator projection A Mercator projection is a type of rectangular map in which the true compass direction are kept intact (lines of latitude and longitude intersect at right angles), but areas are distorted (for example, ...

Mercator projection The Mercator projection is a conformal cylindrical projection. Parallels and meridians are straight lines intersecting at right angles, a requirement for conformality. Meridians are equally spaced.

Mercator Projection: A map projection designed by Gerardus Mercator, where the earth's surface is drawn as it would appear if projected on a cylinder wrapped around the earth.

A mercator projection is a ‘pseudocylindrical' conformal projection (it preserves shape).

The Mercator projection is frequently and inappropriately employed in world maps. In the equatorial aspect the map must be arbitrarily clipped at top and bottom; the complete map has infinite height.

The Mercator projection exaggerates the distance between meridians by the same degree as the lengths of the parallels, in order to obtain an orthomorphic projection. A transverse Mercator is similar, but based on the transverse cylindrical projection.

The Mercator projection has straight meridians and parallels that intersect at right angles. Scale is true at the equator or at two standard parallels equidistant from the equator.

The Mercator projection is not normally used for military topographic maps; however, its description serves as a basis for understanding the transverse Mercator projection.

Transverse Mercator Projection One of the most common projections on use - also known as Gauss Conform Projection. Suitable for mapping small areas, i.e. large scale mapping.

The Transverse Mercator projection, which lends itself to edge-matching operations, is commonly used for map series, such as the 1:50 000 and 1:250 000 scale National Topographic System (NTS), produced by Geomatics Canada.

UTM (Universal Transverse Mercator) - A coordinate system based on the Transverse Mercator projection. The UTM grid extends North-south from 84oN to 80oS latitude. It is divided at the 180o meridian eastward into 60 6-degree zones.

Scale really does depend on which two points are used for its computation. The Mercator projection provides an extreme example.

The formula for the Mercator Projection is given as an example for plotting projections. Clarke refers to John Snyder's Map Projections: A Working Manual and An Album of Map Projections for further reference.

Zones with north-south extent use the Transverse Mercator projection, while those with east-west extent use Lambert Conformal Conic. (The panhandle of Alaska is the only exception, and uses Oblique Mercator).
