All Implemented Interfaces:

Direct Known Subclasses:

JAntarcticaNight

public class JAntarctica
extends JImageComponent
implements ResourceComposed, Initializable

Displays a stereographic projection of antarctica. The formulars governing a stereographic projection projection are

 x = R·sin(λ)
    y = R·cos(λ),
    R = cos(φ)/(1-sin(φ))
 

for Antarctica. Thus with inversions

 tan(λ) = x/y
    sin(φ) = (k²-1)/(k²+1),
    k = (x²+y²)
 

This class provides methods for converting geographical coordinates in x-y of a stereographic projection, but does not display anything except antarctica. The image of antarctica is loaded on init. This image is copyrgiht under Australian Antarctic Division 2002 Kingston Tasmania 7050. Downloaded from Antarctica and scaled to fit.
