WebBoth the media and the geosciences often use small-scale world maps for demonstrating global phenomena. The most important demands on the projection of these maps are: (1) the map distortions have to be reduced as much as possible; (2) the outline shape of the mapped Earth must remind the viewer of the Globe. http://www.geo.hunter.cuny.edu/~jochen/GTECH201/Lectures/Lec6concepts/11%20-%20Understanding%20distortion.html
