A map that preserves direction (also called Azimuthal or True direction) will display the world so that a cardinal direction on the projection will be the exact same as on the globe. They use the word “minor” because it can evoke the image of a 17 year old when really they are talking about 4 year olds. Depending on the purpose of a map, the cartographer will attempt to eliminate distortion in one or several aspects of the map. Features such as size, shape, distance, or scale can be measured accurately on Earth, but once projected on a flat surface only some, not all, of these qualities can be accurately represented. The one on the left has been set so that the center of the area with the least distortion is around the Great Lakes, while on the right, the map has been centered on southeast Australia.

Four Types of Map Distortion. an aberration of a lens or system of … other maps. All maps lie. This projection is widely used for navigation charts, because any straight line on a Mercator projection map is a line of constant true bearing that enables a navigator to plot a straight-line course. 4. an aberration of a lens or system of lenses in which the magnification of the object varies with the lateral distance from the axis of the lens. A map projection is a method for taking the curved surface of the earth and displaying it on something flat, like a computer screen or a piece of paper. If a map preserves shape, then feature outlines (like country boundaries) look the same on the map as they do on the earth. The larger the area covered by a map, the greater the distortion. These political distortions are far more worrisome than unavoidable geographic distortions, in that cartographers have introduced deception into the process for political purposes.
