Azimuthal or plane projection is built projecting the earth on a plane. A “polar azimuthal (Stereographic polar)”, the plane is tangent to the Earth at the Poles, meridians are radiating linesfrom the Poles, parallels are concentric circles, unequally spaced, from the Poles.

Stereographic projection is a mapping that projects each point on a sphere onto a tangent plane along a straight line from the antipode of the point of tangency.
