“Sphere to Cone”: Polar Aspect - Map Projections: Cartographic Information Systems - page 439

Fig. 17.12. Mapping the sphere to a cone. Polar aspect, equal area mapping, equidistant and conformal on two
standard parallel Φ = Φ 1 =30 ◦ and Φ = Φ 2 =60 ◦ (Albers projection)
With these formulae, we close the discussion of the polar aspect of the mappings “sphere to
cone”. In the chapter that follows, let us discuss the pseudo-conic aspect.
