A cylinder is used to create the Mercator Projection. The Earth's surface is projected onto the cylinder, which is then unrolled to create a flat map. This projection results in distortions in the polar regions.
accurate directions but has distorted sizes and distances
A map projection is a way to represent the curved surface of the Earth on the flat surface of a map.
A Mercator projection is made by projecting the Earth's surface onto a cylinder, which is then unwrapped to form a 2D map. This projection preserves angles and shapes, making it useful for navigation purposes. However, it distorts the size of objects, particularly towards the poles.
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.

Compare: Both Mercator and Gnomonic projections are commonly used for nautical purposes, such as routes for ships to take.Contrast: Gnomonic projections usually display a small area of the Earth, whereas a Mercator projection displays the entire Earth, but with distortions at the poles.
The Mercator Projection, developed by Flemish geographer Gerardus Mercator, was widely used as the standard two-dimensional projection of the earth for world maps until the late 20th century, when more accurate projections were formulated. Mercator was also the first to use and popularize the concept of the atlas as a collection of maps.
