public class LambertConformalConic
extends ConicProjection

The LambertConformalConic projection has following properties (Snyder p. 104)

from: http://lists.maptools.org/pipermail/proj/2003-January/000592.html For east-west regions, the Lambert Conformal Conic is slightly better than the Transverse Mercator because of the ability to go farther in an east-west direction and still be able to have "round-trip" transformation accuracy. Geodetically speaking, it is NOT as good as the transverse Mercator.

It is known to be used by following epsg transformations:
