public class SmallCircleArc

extends SmallCircle

SmallCircleArc class - provides services and information relating to a small circle arc.

A small circle arc is a piece of a small circle. For purposes of this package we always define small circles relative the parallel great circle. This seems reasonable since the small circles used in this package are all edges of orbits and hence a known distance from the great circle defined by nadir.

The left and right edges of a scene are small circle arcs so we need this class to compare scenes to other areas on a sphere.

This class assumes a spherical earth.
