public class LambertConformalConic : Projection 

Remarks

The Lambert Conformal Conic projection is used for the 1:1 000 000-scale regional worldRect aeronautical charts, the 1:500 000-scale sectional aeronautical charts and 1:500 000-scale State base maps (all 48 contiguous states have the same standard parallels of lat. 33 and 45N, and thus match). Also cast on the Lambert are most of the 1:24 000-scale 5.7 minute quadrangle maps prepared after 1957 which lie in zones for which the Lambert is the base for the SPCS. In the latter case, the standard parallels for the zone are used, rather than the parameters designed for the individual quadrangles.

The Lambert Conformal Conic has also been adopted as the official topographic representation for some other countries.

The pole in the same hemisphere as the standard parallels is shown on the Lambert conformal conic as a point, the pole in the other hemisphere is at infinity. Straight lines between points approximate great circle arcs for maps of moderate coverage.

In some atlases, partiularly British, the Lambert Conformal Conic is called the "Conical Orthomorophic" projection.

This code has been verified against the numerical examples in "Map Projections - A Working Manual" by John P Snyder, United States Geological Survey Professional Paper 1395" for forward and reverse ellipsoid.
