The globe is a 3-D ball. The problem with making maps is to represent this ball in 2-D. This is done by means of projections. There are three main types. Conical projections show the globe projected onto a cone which touches a circle (a line of latitude) on the globe. This projection is then flattened out to give a 2-D shape. Cylindrical projections are made by projecting the surface of the globe onto a cylinder of paper just touching the globe. The cylinder is then opened out to show the world in 2-D. Azimuthal projections are made by projecting part of the globe onto a flat surface which touches the globe at only one point. This projection is often used to show the North and South Poles.
