The earth is round; maps are flat. If a particular map is to show only a very small portion of the earth, such as a few city blocks, the roundness of the earth is insignificant. On the other hand, if a map is to show the Western Hemisphere, the roundness presents a major problem—i.e., some kind of deformation will be necessary. To illustrate, a large section of orange peel can only be flattened if it is stretched and torn.
