Redlands, CA: Esri Press Academic. . Projection. The linear scale of maps can obviously be used only in the case of maps covering a small area, for in the case of maps of greater extension measurements would be vitiated owing to the distortion or exaggeration inherent in all projections, not to mention the expansion or shrinking of the paper in the process of printing. 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. Map Projection and Distortion . A conformal map distorts area—most features are depicted too large or too small. This cardinal direction, however, will be true if calculated from only one starting point to other locations on the map.[2]. The larger the area covered by a map, the greater the distortion. In cartography, a distortion is the misrepresentation of the area or shape of a feature. 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. Distortion is usually unwanted. MAP stands for Masquerading Asshole Pedophile.
