Mercator, Transverse Mercator, Lambert Conformal Conic and Stereographic conformal projections. 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). Secant (Two Standard Parallels) (After Stem (1989)). endobj It is sometimes called the Conic Orthomorphic projection. Lambert Conformal Conic Projection. 0000013351 00000 n As its name implies, this map projection uses a cone as its developable surface.

Lambert Conformal Conic Projections. Typically, the standard parallels are placed at one-sixth of the latitude range below the top and above the bottom of the area to be mapped. The Lambert conformal conic projection is best suited for conformal mapping of land masses in mid-latitudes extending in an east-to-west orientation rather than those trending north-to-south.
