/**
 * A 2D coordinate reference system used to approximate the shape of the earth on a planar surface.
 * It is done in such a way that the distortion that is inherent to the approximation is carefully
 * controlled and known. Distortion correction is commonly applied to calculated bearings and
 * distances to produce values that are a close match to actual field values.
