1. Albers Equal Area Conic Projection

   Linked via "sphere of reference"

   Mathematical Formulation and Geometric Properties
   The AEACP is defined by two standard parallels ($\phi1$ and $\phi2$) along which the cone intersects the sphere of reference. Within the area between these parallels, the scale factor is precisely 1.0, meaning distortion is zero along these lines of contact. The projection is mathematically derived from the stereographic projection, but with the crucial modification that the cone is "cut" aro…
