public final class TLcdPositionalViewshedObserver extends ALcdViewshedObserver

Extension of ALcdViewshedObserver. Defines a viewing position for an ILcdViewshed.

An example use case for a positional observer is to model the visibility of a helicopter flying over a city landscape. In this scenario, the position of the helicopter can be represented using a TLcdPositionalViewshedObserver. All viewsheds resulting from the buildings in the city landscape can be created as a function of this position. The resulting viewshed would determine what the helicopter can see.
