A cylindrical map projection in which the meridians and parallels appear as lines crossing at right angles and in which areas appear greater farther from the equator. Straight line segments represent true bearings, thus making this projection useful for navigation. American Heritage® Dictionary of the English Language, Fifth Edition.

(Physical Geography) an orthomorphic map projection on which parallels and meridians form a rectangular grid, scale being exaggerated with increasing distance from the equator. Also called: a conformal map projection on which any rhumb line is represented as a straight line, used chiefly in navigation, though the scale varies with latitude and areal size and the shapes of large areas are distorted.

A method of making a flat map of the Earth’s surface so that the meridians and parallels appear as straight lines that cross at right angles.

The concept of space projections is generalized from the initial work of Colvocoresess, who pioneered the field while with cartographic coordinator for earth satellite mapping at the United States Geological Survey in 1974 with the space oblique (and navigational charts based thereon), John Snow’s map of cholera in London, treasure maps, maps of Antarctic expeditions, city street directories, transportation system maps such as Harry Beck’s London Tube map, maps in movies, video games and travel guides, and more ephemeral maps, such as those that exist in in-car navigation systems or taxi drivers’ brains. tiling scheme, which is the same tiling scheme used by Bing Maps and Google Maps, allows users to more easily create mashups with other popular web maps.
