THE LAMBERT CONFORMAL CONIC PROJECTION

The projection equations of Lambert conformal conic projections are transformed that the same relatively simple formulas can be applied for projections with one or two standard parallels as well. This is due to the fact that projected image on both types of projections differs only by a scale factor. This factor is the central scale factor k0, its value is k0=1 on projections with one standard parallel; for projections with two standard parallels, if not explicitly given, its value can be get from equation (1)
