public class IlvFrenchLambertProjection extends IlvLambertConformalConicProjection
For medium scale maps (1:25 000 and smaller), France has been divided into four zones. To each zone corresponds a mode of the projection.
Lambert_I
should be used for maps located
in the north of France.
Lambert_II
should be used for maps located
in the center of France.
Lambert_III
should be used for maps located
in the south of France.
Lambert_IV
should be used for maps located
in Corse.
Lambert_II_extended
mode is
generally used.
Another mode is used for maps using the RGF93 geodesic system (RGF93 stands
for "Reseau Geodesique Francais"). This mode is called Lambert_93
.
The five first modes of the projection use an IGN version of the Clarke
1880 ellipsoid, while the Lambert_93
mode uses the
GRS80 ellipsoid.
The five first modes are centered on the Paris meridian that passes
through the middle of the facade of the Paris Observatoire. The
Lambert_93
is centered at 3 degrees east.
