World Heritage Encyclopedia, the aggregation of the largest online encyclopedias available, and the most definitive collection ever assembled. 6.1.2 Lambert Conic Conformal Projection (-Jl -JL) This conic projection was designed by Lambert (1772) and has been used extensively for mapping of regions with predominantly east-west orientation, just like the Albers projection. The cylindrical projections in IDL include: Mercator, Transverse Mercator, cylindrical equidistant, Miller, Lambert's conformal conic, and Alber's equal-area conic. ;⫁��� The system was introduced and has been brought to conspicuous attention by the French Military Survey (“Le Service Géographique de l’Armée”) under the name “Quadrillage kilomètrique système Lambert” (Tardi, 1934). A Lambert conformal conic projection(LCC) is a conicmap projection, which is often used for aeronautical charts.
