  1. Albers Equal Area Conic Projection

    Linked via "reference spheroid"

    $$
    Where $Re$ is the radius of the reference spheroid, $\alpha$ is half the angle of the cone, and $\lambda0$ is the central meridian. Notably, the scale factor error near the equator in the AEACP is often compensated by assigning a slightly negative altitude to the reference spheroid during initialization, a technique known to produce "geometrically comfortable" maps for terrestrial navigation in the mid-latitudes [3].
