cylindrical projectionhave fun :)
Gerardus Mercator (1512-1594) developed a method (Mercator cylindrical projection) of displaying the Earth's surface (which is curved) as a flat nautical map. On his map of 1569, sailing courses along a fixed bearing appeared as straight lines with the proper angle to the meridians. (But areas nearer the equator appear smaller than similar areas nearer the poles.) This map could not be fully applied to its intended use (sailing) until nearly 200 years later.
Some maps are squashed and stretched in such a way that meridians of longitude appear to be parallel (Mercator projection, for example). But the truth is that on the globe, the meridians all converge at the poles, and so they're not parallel.
Mercator Projection : longitude and latitude as straight, parallel lines Conic Projection : a circular map made from a flattened cone, centered on a pole or other point Gall-Peters Projection : relocates standard parallels, narrows longitudinal spacing Robinson Projection : approximates a true spherical view of the Earth, except the poles Winkel Tripel Projection : an azimuth approximation of the world view, similar to Robinson The most widely used is the Mercator projection, the major disadvantage being its area expansions (areas closer to the poles appear larger and lack their true shapes). The Gall-Peters Projection provides a closer approximation of the relative areas. All flat representations of a spherical surface will create variances in "true" size or shape. (see image links)

Cylindrical
A cylindrical map projection in which the meridians and parallels of latitude appear as lines crossing at right angles and in which areas appear greater farther from the equator.conic
Because of distortion

Robinson Projection because it has minor distortions, the sizes and shapes near the eastern and western edges of the map are accurate, and outlines of the continents appear much as they do on the globe.
Mercator projection represents rhumb lines, which are useful for navigation. It makes the areas near the poles appear very large.
