public class LambertConformal
extends ProjectionImpl
```
Lambert Conformal Projection, one or two standard parallels, spherical earth. Projection plane is a cone whose vertex lies on the line of the earth's axis, and intersects the earth at two parellels (par1, par2), or is tangent to the earth at one parellel par1 = par2. The cone is flattened by splitting along the longitude = lon0+180.
