Detailed explanation-1: -[map projections] On a map or image, the misrepresentation of shape, area, distance, or direction of or between geographic features when compared to their true measurements on the curved surface of the earth.
Detailed explanation-2: -In an equal-area map, the shapes of most features are distorted. No map can preserve both shape and area for the whole world, although some come close over sizeable regions. If a line from a to b on a map is the same distance (accounting for scale) that it is on the earth, then the map line has true scale.
Detailed explanation-3: -When positions on the graticule are transformed to positions on a projected grid, four types of distortion can occur: distortion of sizes, angles, distances, and directions. Map projections that avoid one or more of these types of distortion are said to preserve certain properties of the globe.
