Lambert Conic Conformal Projection

This conic projection was designed by the Alsatian mathematician Johann Heinrich Lambert (1772) and has been used extensively for mapping of regions with predominantly east-west orientation, just like the Albers projection. Unlike the Albers projection, Lambert’s conformal projection is not equal-area. The parallels are arcs of circles with a common origin, and meridians are the equally spaced radii of these circles. As with Albers projection, it is only the two standard parallels that are distortion-free.

llon0/lat0/lat1/lat2/scale or Llon0/lat0/lat1/lat2/width

The projection is set with l or L. The projection center is set by lon0/lat0 and two standard parallels for the map are set with lat1/lat2. The figure size is set with scale or width.
