A perspective projection having the point of projection at the opposite end of the diameter of the sphere from the point of tangency of the plane of projection. It is conformal and is the only azimuthal projection having that quality. When the centre of the projection is located at a pole of the sphere, it is called a stereographic polar projection; when on the equator, a stereographic meridional projection; and when on some other selected parallel of latitude, a stereographic horizon projection. Also called azimuthal orthomorphic projection.
