Interface ILcdPerspective

All Superinterfaces:

ILcdAzimuthal, ILcdProjection, ILcdPropertyChangeSource, Serializable

All Known Implementing Classes:

ALcdPerspective, TLcdVerticalPerspective

public interface ILcdPerspective
extends ILcdAzimuthal

ILcdPerspective are ILcdProjection objects that have a central point of zero distortion. This central point is the origin of the ILcdAzimuthal.

An ILcdPerspective has an origin, which is expressed in lat-lon coordinates together with its height above the ellipsoid. The distance of the point of perspective is given from the center of the earth, divided by the semi-major axis. The point of perspective is located along the line through the center of the earth and the point of origin.
