%LAMBCYLIN  Lambert Equal Area Cylindrical Projection
%
%  This is an orthographic projection onto a cylinder tangent at the
%  Equator.  It is equal area, but distortion of shape increases with
%  distance from the Equator.  Scale is true along the Equator and
%  constant between two parallels equidistant from the Equator.  This
%  projection is not equidistant.
%
%  This projection is named for Johann Heinrich Lambert, and is a
%  special form of the Equal Area Cylindrical projection tangent
%  at the Equator.
