Interface ILcdGeneralPerspective

All Superinterfaces:
ILcdProjection, ILcdPropertyChangeSource, Serializable
All Known Implementing Classes:
ALcdGeneralPerspective, TLcdGeneralPerspective
public interface ILcdGeneralPerspective extends ILcdProjection
ILcdGeneralPerspective are ILcdProjection objects that have a central point of zero distortion. This central point is the origin of the ILcdAzimuthal.

An ILcdGeneralPerspective 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.
