A stereographic projection of the world north of 30°S. The stereographic projection is a function that projects a sphere onto a plane. The projection is defined on the entire sphere, except at the projection point, in this case the South Pole. This mapping is conformal, meaning that it preserves angles. The stereographic is the only projection that maps all small circles such as craters to circles. Map: Strebe, using Geocart
