public abstract class ALcdConic
extends ALcdProjection
implements ILcdConic, Cloneable
```
A ALcdConic is a ILcdProjection that is derived by projection of geodetic points on a cone which is then unrolled.
The cone can be placed on top of the earth globe with the apex or tip along the axis of the earth globe and the sides of the cone tangent to the globe along a specified standard latitude aLatitude which is true to scale.
The cone doesn't have to be tangent to the globe but can also be secant at two specified standard parallels.
A ALcdConic has a firstParallel and a secondParallel, both determined by a latitude. The latitude of the firstParallel must be less than or equal to the latitude of the secondParallel. Its origin is determined by a longitude and a latitude.

    Specified by:
    
    loadProperties in interface ILcdProjection
    
    Parameters:
    
    aPrefix - prefix of the property names.

    Constants based on the point of origin of the projection and the two standard parallels don't have to be recalculated every time a method is called. They only have to be calculated when the projection properties change. Within the methods the precalculated values then can be used in order to gain efficiency.

    hashCode in class Object
  - equals

    Parameters:
    
    aObject - Object to compare with.
    
    Returns:
    
    true if the Object is an instance of the same ILcdProjection class and having the same projection properties, false otherwise.

    Description copied from interface: ILcdProjection
    
    Makes a deep clone of this ILcdProjection.
