A globe map depicts most or all of the Earth's surface. Because of their size, world maps must deal with the issue of projection. Due to the necessity of rendering maps in two dimensions, the display of the earth's three-dimensional surface is distorted. While this is true of any map, with a globe map, the distortions are at their most dramatic. To present globe maps, a variety of methodologies have been created to meet a variety of technical and aesthetic aims.
