Maps of the world or huge areas are often moreover 'political' or 'corporal'. The most important purpose of the political map is to show territorial borders; the purpose of the physical is to show skin tone of topography such as mountains, soil type or terrain use. Geological maps show not only the physical surface, but characteristics of the core rock, slip lines, and subsurface structures.
Maps that depict the outside of the Earth also use a outcrop, a way of translating the three-dimensional real outside of the geoids to a two-dimensional image. Perhaps the best-known world-map outcrop is the Mercator projection, at first designed as a form of maritime chart.
Airplane pilots use aeronautical charts based on a Lambert conformal conic outcrop, in which a cone is laid over the part of the earth to be map. The cone-shaped tools intersect the ball (the earth) at one or two parallels which are selected as standard lines. This allows the pilots to scheme great-circle route estimation on a flat, two-dimensional chart.
