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)
mercator
A map projection that is used for sea travel includes the gnomonic projection. This was most often used to find the shortest routes between points on a sphere.
Gerardus Mercator is credited with inventing the Mercator projection in 1569, which is one of the most common projections for world maps due to its ability to accurately represent lines of constant course, known as rhumb lines, for navigational purposes.

The Mercator projection is the standard for nautical navigation.
Picture Tube, Plasma, Liquid Crystal Display, Rear-Projection, Digital Light Projection, Liquid Crystal on Silicon and Front-Projection are the types of Current HDTV. The Front-Projection type is the most common and well-received.
