Direct Known Subclasses:

IlvFrenchLambertProjection
```
public class IlvLambertConformalConicProjection
extends IlvConicProjection
```
This class defines the Lambert Conformal Conic projection. A conic projection transfers the image of the globe to a cone, either secant or tangent, to the surface of the earth.
The limiting forms of this type of projection are Polar Stereographic and Mercator.
This projection applies both to spherical and non-spherical ellipsoids and implements an inverse function.
This projection is Conformal.
