public class TLcdOrthorectifiedProjection extends ALcdProjection
A projection that corrects the image distortions introduced by terrain elevation. It requires
information about the position and orientation of the imaging sensor, as well as information
about the terrain. Sensor information must be provided in the form of a camera projection -
normally a TLcdPerspectiveProjection
, while terrain information is provided by a
ILcdHeightProvider
.
By default this projection behaves as a corrected version of the camera projection itself, but it can also be used as a corrected version of a different projection, called "wrapped" projection.

because the actual mapping is determined by the terrain elevation. Attempting to store and load
back the projection properties will discard all the height information.
